We removed EVERYTHING from this car to make it faster. We carefully took out the seats, the carpet and even the rear wiper to try and shave seconds off of our lap time.
We’re trying to beat a supercar with just £15,000. We bought a Subaru Impreza for just under £4000 and since then we’ve fitted a new clutch, a set of coilovers and some semi-slick track tyres.
With Scott off being a racing driver, we put the Subaru on the scales to get the benchmark number. But before we could do that, we had to figure out how to actually use it.
Scott was overtaking SUPERCARS well over 50 times more expensive than the Subaru. With one Porsche left behind, Scott went after a Ferrari 488 Pista.
Not content with shaming supercars, Scott overtook a Radical before passing the Porsche AGAIN.

When the money isn't enough. You can sell the parts😉
Great irl advice if you're really doing this but would probably take a while for the video.
Add that to the budget!
Or the driver.
That's brilliant
For me is a really interesting test. Don't think stock sti is a lot better than stock wrx wagon. And wrx sedan is completely the same than scooby wagon
Firstly I'd like to say that I love that you've gone for the "it's now a practical van" approach. Secondly: removing the sunroof and welding the hole shut could save a few crucial kg at the highest point of the car. Also: I can't exactly remember how adjustable the suspension is but I'd also suggest to retune it since it's now set up for a car that's 135kg heavier.
I think they didn’t get the full suspension tune yet in that video because they had stuff like this in mind.
You can buy a fibreglass insert for it, im pretty sure. edit: i now see they covered that in the video.
Car is to bouncy, which indicate to harshly dampening.
Sway bars is about the only other costly upgrade.
@@Jonesy781 Yeah It'd be clever to make an episode like "how much faster is pro suspension tuning"
"We've borrowed dad's subaru" got me chuckling pretty hard
that car but in blue was my dads car for 15 years but it blew up in 2019 sadly.
@@Zaxaphone my dad's subi blew up in 10
@@sufferr2914 must have been riding it really hard to blow it up in ten minutes
it’s weird because my dad has an identical car just it’s a saloon. Same colour.
@@Zaxaphone Was it an IED?
Does selling the seats and interior parts add up to the 15k budget?
Fair play as far as I'm concerned!
@@grayaj23 i back it up as well
should be allowed really because realistically thats what someone would do
There's stuff there I'd buy lol
I bid £80 for that passenger seat.
I was a few garages down from you guys in my Gtr! I wondered what you were up to! Absolutely brilliant 😂
We heard whenever you flew past!!
@@OVERDRIVE.studios yes it’s rather loud haha! Look forward to seeing the result of this video! Bet it saves you a good few seconds
@@Lofi.z34 Thankyou 😁
Lol awesome
If you poke around behind the wheel arch liners (near where they meet the side skirts) you should find about 5kg of mud that will have built up over the years
😂 Great point
Lmao that’s funny and true same with the brz youll get some crud in the front fenders some how I had leaves in mines xD
in my Kia Rio it was about that much (in total in the front and rear wheel arch liners) )))))))))))))))))))
This mainly shows that track knowledge and skill+experience is vastly more important than equipment
Fast driver in a slow car is often quicker than a slow driver with a fast car. Personally I actually prefer to drive slower cars fast as it's way more fun, requires a bit of skill and running costs are way lower 😆
@@justincase9471 And it's easier to drive a 105 brake golf to the limit than it is a 400 brake GTR ;)

@@SpartanMJO12 id be willing.ling to bet its easier to drive a gtr on the limit than it would be a clapped out go,d
So true. The driver is 90% of the track time performance
You should really put that grey bar back in under where the rear seat was, you're probably losing more in body stiffness than you're gaining by saving 6lbs
Maybe you have a big point here
I thought the same thing, why remove a rear sway bar? They also potentially messed with aero by removing the side fairings
@@brandonfields5720 it was a body brace not a sway bar but yeah I thought the same about them removing the rocker covers
@@user-jk5rt4kd8q nomenclature certainly isn't my strong suit. Rip. But yeah, they definitely made some interesting choices
Didnt make any sense to me.. removing something structually solid like that, essentially in a big empty tin can
I think thicker ARBs and strut braces would be worth it after you fitted the coilovers. I did felt quite a difference after in my Subaru.
10:25 It's a WRX wagon, that's completly normal phenomenom. I'm actually amazed that in the UK in a WRX Wagon there are still rear strut towers left!
I still think the Wagon still looks close enough to a rally-car if you squint enough
Crouch and look at it from the front, totally a Subaru rally car
Don’t forget to spray a bit of mud around the bumpers.
A lot of actual rally cars are hatches
or drink enough...
Can rally just fine in a wagon!
@6:04 I wonder if this is not the underseat brace potentially providing some extra rigidity like a rear tower brace. Maybe it would be faster with it 😂
Yep, should definitely stay
That brace is for side crash protection for the rear seats. It does little to nothing for chassis rigidity.
Yes, I'm not sure why they removed it lol
@@DeadRedRider it does a fair bit in our experience
Thats exactly what its for , it'll handle worse now and probably wouldn't pass as road legal or insurable
Love watching this Suba get quicker each episode, and how much fun the guys are having doing it.
I hope that they will stay away from tuning the engine 😉
@@justincase9471 team supercar?
i've grown attached to dad's subi now... it's like our little baby growing more ripped with each gym session.
No A/C delete? I think that'd be another 10-15kg. And free as well.
Did it in mine 13 kg
You need to purchase a blanking plate, and we decided to save the cash.
@@OVERDRIVE.studios but you could remove a Part of it couldnt you? Remove everything Exept the compressor so the belt is on tension. Or am i missing something?
@@jimmyschwarz9075 the compressor and tensioner are about 4kg probs.. As well you gotta properly degass the ac system, which a technician with right vacuum gear can do, and you pay for that. Back yard degassing is bad for ozone and big fines. But bad for ozone.
@@OVERDRIVE.studios Ahh, I didn't consider that. Cheaper than replacing a seat with a racing seat though, and about the same weight saving.
We raced an old alfasud, had the body acid dipped to remove all underseal etc, totally stripped the car, but added a full rollcage , got it down to 750kg from 900kg standard which I thought was fairly impressive and it made a huge difference to the performance from the 175bhp race motor....
I have almost that exact same car (cloth interior instead of leather). The front passenger seat has been out for almost 1.5 years because I've been building a new house and from passenger wheel well to hatch I can get about 9.5 feet (2.9m) of lumber. On the rare occasion that my wife needs to ride, she actually loves the back seat with tons of leg room. WAY more practical without all of those interior bits!😃
Technically the things you took off could be sold and added to the budget
You could also remove the sound deadening material on the floor of the car with dry ice and a hammer.
it actually removes like 15kg in some old cars ! u need liquid azote
@@TheTrooperMB15 kg?!?!
@@PimSchouten apparently theres that much in a car , at the back you have plenty on the rear struts , back seats ..
@@TheTrooperMB yeah apparently. I’ve build racecars, but never came close to 15 kg, that’s why I’m so amazed haha
@@PimSchouten someone removed as much on a sentra B13 .. was he lying .. i don't know :D
I'd definitely put that Chassis brace back in the boot. It's definitely worth the 3kg until you get a roll cage
I agree a rigid car allow the suspension to work as designed.
This is why the brilliant engineer's at Mitsubishi Australia designed the 380 with only a ski port and no folding rear seats.
You took a Subaru and turned it into every 90s JDM fan's Honda Civic 🤣
I love this channel! This helps me have a better understanding on cars.
Not bad for a clapped-out car eh?
I've finally subscribed! You drew me in with this build series. I love Scott's race analysis and commentary, but this addition is fantastic!
Definitely do a dry lap time next time guys!! I really want to see the time difference!!
Gotta love a place where you can go back and forth between two circuits that have been used in F1 in a normal day.
This is one of the best auto series I've seen on or offline. Really enjoying it chaps! 👌🤘
Don't forget to remove the motors for the sunroof, rear wiper, and rear windows. Getting the A/C system properly drained shouldn't be too expensive. Either that or maybe the A/C already had a leak when you got the car. You could probably replace the sunroof with an acrylic panel and some silicone to seal it.
across the water over here… I absolutely love this series. Top 3 on KZhead for sure. Hope to see more of these in the future🔥👊🏼
These videos are too short for how long we have to wait for each
Just a little tip to keep in mind. I noticed this even when i just put down the rear seats, the torsion resistance of the whole rear went down drasticaly, so i would strongly recomend some rear strut tower bar to regain it.
Putting a cage in would make a dramatic difference to the stiff factor
You guys are ABSOLUTELY BRILLIANT TOGETHER!!! How has no one given you lot a series yet? Loved every second ❤ Cheers from St. Louis, Missouri USA 🇺🇸
The video should be called Bell ends go wild. Love your work. But, the bar under the rear seats that weighs 3kg is a structural stiffness bar. You might want to keep that one. And in a Subaru weight in the rear is better. Removing weight from the front is more important. So, 86 the air-con system, relocate battery to rear, and plug and remove the moisture collector under the air box. Also, due to the loss of heat protection. I suggest cutting a section out near the a and b pullers on the inside of he front panels and putting another hole near the mirrors will vent the heat out. As a bonus your mirrors will not need to be defrosting. So you could get a practicality point from that. Oh, and rear Sway Bars in Subaru are more important especially in wagons.
Owning two wagons in almost this exact spec makes me love your choice of vehicle even more :)
As an owner of an 05 Saab 92x aero (wrx wagon) that I currently daily, but plan to make a track car.. I found this series awesome. I also have a blown-out front driveshaft boot that sprayed grease everywhere.. and a small crack in my windscreen, a nearly dead clutch, and i plan on getting those exact bc coilovers lol. And ive thought about doing 'some' weight reduction as-well. And always thought fully-stripping it would be epic if it wasnt my daily. Id keep the front door cards & both front seats though
10:37 the ultimate weight reduction rust (some might say it's lighter than carbon fiber)
found this channel recently, really enjoying it. great video!
I'm afraid they went in backwards. You start by getting it to "fighting weight". Cage it and skin the doors. Then you get the suspension and tire compound working. Once you change the weight the spring rates will be all wrong and the tires might not heat properly. Also if you are light enough you might even downsize the brakes and wheel width because you are fighting less mass. Use a lawnmower/Honda size battery located centrally in the car. Cut 10 Kilos/20 lbs of copper wiring to accessories you aren't using out of the wiring loom. Lose the roof rack and the fog lamps. Remove the alternator from engine and run it off the rear diff. Moves weight lower and weight bias to rear.
Holy words... also maybe remove AC system and vents
spot on
Impressive! I would do the sunroof delete too though because it could help lower your centre of mass.
Loving this series! All that weight was not helping the lap times. Shame the English weather robbed us of a time comparison but it looked fun on track.
Great job guys! Now all you have to do is: Do it again in the dry! I think it will be REALLY COOL to see how things are in the dry, because the supercar owners are braver there and with Scott behind the wheeel, everyone will get the shock of their life when they see an old family car overtanking their expensive track toy.
Being a kid born in 86, I was a junior in high school when the WRX and STi’s came to America along with the EVO and Dodge releasing the SRT-4. My best friend at that point in time had an 01 2.5RS that he kept N/A but added the obligatory intake and catback exhaust along with a cam and injectors. What he did that surprised everyone was spent $8k on the top tier suspension, brake and wheel/tire mods. That car, while in the straights would get its doors blown off by even a stock STi, more than made up for it with its ability to blow through corners with what felt like limitless grip and just the right about of over/under steer. Even at the limit that 2.5RS gave me confidence that even a 911 Turbo S couldn’t match in terms of subjective feeling. 36 years old now and I recently finished building my own 01 2.5RS but I went with the EJ25 route that’s relatively tame, however I took the same route as far as suspension, brakes wheels and tires and anyone who has driven it fails to stop smiling their entire drive
Take off the sunroof and tape it off! Also to add to the others sell the components and add it to the budget Also the ac off please take even the vents off cabin air filter and i didnt see them take the stereo unit? Small stuff but adds up
There's another 100lb you could take out of that interior... sunroof, gut the doors and dash for starters. I gutted my Lexus LS400 and even with a full cage, full size battery and fire system its 2900lbs!
Loosing doors will most probably increase the lap time. Too much air faffing about without the doors. Removing sunroof and taping it off, taking away dash plastics would have been great though
Tracking an LS400... I tip my hat to you!
Ditch the air con and the stereo as well
lexus uses thicker steel
@@thecompanioncube4211 gut the doors means take them all the way down to the skin. Window regulators and power locks out.
This is fantastic, I have an '07 Subaru Impreza wagon of the same colour here in BC, Canada and it is totally amazing, especially in bad road conditions. This is so COOL!!
I remember when you started this channel as a spin off of Driver 61. I wondered if it was worth it when you only had 20k subs, awesome to see you with over 260k subs now!
Speaking about weight reduction, a set of very light wheels could be an idea? If not for this series, for a future video it'd be very interesting to see a comparison between very light and heavier wheels and how much it can actually affect the lap times
I agree, especially because it's 'unsprung' rotating mass. It would effectively put more power to the ground & help it turn in/change direction better on top of just reducing overall weight. I believe for every (lb.) saved with wheels/tires, its equivalent to either 4x or 10x (dont remember which one lol) as much sprung weight
Sell the parts and get a sunroof delete kit to improve the centre of gravity a bit and maybe also a single bucket seat for the driver if you get enough money from the parts, as this will not only save a little weight but also keep the driver in a better, more stable position, which can also make a small difference :)
do a pre set up and post set up by aligning and correctly adjusting suspension to the like of the driver, that's incredibly game changing
I love this video soo very much Top gear vibes Keep up guys
I will give you guys a bucket seat with rails for a new age inpreza already on.
Drop us an email! It's in the About section on the channel.
Can't find an email address on the about
If it's lighter now, you can lower the suspension and make the car even faster
Lowering the suspension without correcting the roll centres almost never makes the car faster because you actually generate more body roll and strange handling characteristics if you lower the car significantly.
“….but it’s now a better van🤷🏼♂️” made me literally LOL. this has been an awesome series guys great job. Great to see the progression and what the effect on the time is.
Wow love these kind of videos! U have a new subscriber.
Less weight is free so doesn’t affect the modding budget. Get as much ambient air as possible blasting into the air box and intercooler
Actually its profit
Less weight, more pocket change!
its not air in (there's plenty) its getting it out; need more exit area.
The air that we want to bring in will get out through the cylinder, manifold, turbine and exhaust. I’m talking about getting ambient air to the compressor instead of hot. The duct will be sealed. You’re talking about air pressure in the engine bay generating negative downforce. Different argument with a different solution for a different reason.
Maybe consider hardened titanium lug nuts , they actually make quite a difference. If you can get a solid used set , definitely do so! They are a bit pricey...
Love this ready for the next one.
This series is so brilliant
I think these guys should be the new top gear
Seriously. They have great chemistry together, very entertaining car content, and plenty of humor
You guys should also remove the muffler and just leave the cat on, mufflers are super heavy. Also remove the sunroof and replace it with a thin piece of aluminum. You can also buy some used sway bars from an STI for super cheap that would help too. You could also put on a used, larger diesel turbo and get more power with a tune.
LOVE this series!
I've always wanted to see this tested irl!!! Nice!! I wonder how this affects MPG as well
You guys could sell the parts to a scrap yard and get a bit moe budget
Really surprised at the amount of weight that came out of it, was expecting less than half that! Stock Subarus are FAT
At 6:23, "I'm sorry Ms. Jackson, oooooo! I am for real!"
I had exactly that car as our family car a few years ago. Was a superb car with the produce kit on it with 280bhp. Fuel bill was a bit pricey though.
After removing weight, you need to set the suspension ride heights and corner weights again.
That's actually a really good point
Does it have sound dampening and will you be removing that ? ChrisFix said his weighted quite a bit and was worth removing.
I think it's glued to all the plastic trim they took out. I have the same car (USDM) and I had to take the trim off the rear hatch to replace the handle once.
@@salacommander2674 it would be Chrisfix froze his and broke it up with a hammer. Seems to need the same
25lbs in my 93. A little bit more in that wagon.
I love this Series I have an 03 WRX wagon that I’m going to be stripping down and making it into a street go kart type vehicle so basically cutting off the whole body and building a real cage I’m doing extreme weight reduction so it’s interesting to see the build on this and how much weight you lose with just interior stripping!!!
With the suspension and tires an alignment and balance would make a huge improvement. Best bang for the buck in my opinion. Of course you need to add the lightness first.
you should've pulled that stuff out carefully and sold it all. Also, I'm fairly certain that bar for the rear bench is for added structural rigidity
watching you destroy good interior pieces hurts...
Damn impressive that he was able to pass those supercars. Racing driver or not.
Its really not impressive. It was probably a public track day and alot of expensive motors like that are driven very carefully and nowhere near their max performance.
"I'm having too much fun, and I don't give a toss". Spot on mate :)
Keep these coming!!!
You gonna put some big aero wing on it to generate some downforce and faster corner speeds?
adds weight and drag on the straights.....
@@spinnetti it's all about balance. A car can also be too light.
the track that they took the base lap times was a power track so less drag makes more sense but trying to beat a car that has at least 300hp more than you around a power track doesn't, if they can add some downforce and take the base laps in a downforce focused track, they will have more chance
Did I miss EP4?
damn, I love this series!!!!
Love how you guys are just Top Gear on KZhead 😂 it's quite amazing!
You guys should of done at least 5 laps each, cut the first two off then average the last three, Anytime my club has a meet or a timed event both the car and us warm up to the track in some cases going from 1:42 time to a 1:14 time lowest during the day with car running nominal the whole day.
This is like a professional copy of what CarThrottle did with their mitsubishi Spacestar, and I'm all for it
Love these car before and after mod videos
Cobb downpipe/20g turbo/turbo inlet pipe, Tomei equal length headers and up-pipe, Cobb Ti catback, fuel injectors and rails, fuel pump, front mount intercooler, radiator, intake, bypass valve, boost controller, custom tune. done
In regards to todays sponsor, if someone wants to chuck me £10 I'll send you a pointless piece of paper that'll say you're a supreme leader which carries just as much weight as one of these buy online Lord titles.
Yeah the ritle things are shit
Everyone needs more than their salary to be financiaIIy stable. The best thing to do with your money is to lnvest it rightly because money left for savings always end up used with no returns.
Nicely said indeed, I think Mr Ryan Morrison is the best step to take following the current situation of the world economy, I have never believed in Bitcoin or crypto currency in all, but this has been a life changing encounter today!!
This series is so so good
Great videos but would love to watch in 60 fps, consider uploading it's much nicer watching cars drive! Also funny seeing you struggle with some bits that I could never figure out how to get off without watching a KZhead video lol
That bar you guys took out from under the rear seat is a chassis brace and is considered relatively crucial for frame rigidity….great vid tho !!!
I'll be doing the same thing in my $400 Plymouth Laser RS I cannot wait for this summer
I really love this series
Tilt the sunroof up for a stepped roofline profile closer to the ideal teardrop shape silhouette. Also turn up the HVAC blower so it pumps vented air outward reducing boundary air in front of the vehicle. Like an air bridge out the roof.
I love this series!
1.29 is pretty good for that full weight, impressive . Was that with semi slicks? I got 1.32 in my stock 2001Subaru Legacy. Stock brakes ,tyre, suspension etc. So you’ve given me a new target!
I did this to a car for ice racing once. The primary difference was that the heater could no longer keep up with the warm air fleeing through the sheet metal.
Need to take power steering belt off as well as ac and that will give you a surprising amount of free hp
Nice work lads!
I have been commenting for YEARS on car channels to do a strip down and show the actual weight loss.... AWESOME VIDEO!
That wet run was amazing!
just so you know, flat bottomed underbody can reduce drag by at least 15kg :)
These video's are fun experiments!
My skyline r34gt-Four was 10secs to 100kph. After stripping and lightweight flywheel with full suspension overhaul it’s 7.8secs Weight makes a huge difference.
i think they should now go ham on with the leftover budget to beat the supercar now, and then i would love to see a series on making the car practical for daily use. like that would be amazing to see . this car being turned into a daily drive monster.
9:52 LMFAO
