Thank you to all the mod creators that make incredible mods for us.
it really is just like real life. trophy truck teams and others will take footage from a road in a pickup truck, with the tt blasting down the side of the highway, and they will rewatch and tune. obviously that's not the only thing they do, but it just goes to show the game is so realistic that you even mimic a real life suspension tuning technique to get the best outcome. I worked for almost 3 years for Fox Factory, in the bike division. All the suspension principles in the game are exactly like they are in real life. I mean they even simulate the nitrogen charge behind the IFP in the bypass shocks. Beam has unintentionally become the best offroad simulator ever made, and probably will ever be made. Just look at how many real desert racers play this game, including people from big TT teams.
I’d love to hear more about your time at FOX. Feel free to jump in discord! Thanks for the words. I couldn’t agree more!
I know a few trophy truck drivers play this I can remember Brock Dickerson and Christopher polvoorde If I'm not wrong, I'm into deset races as a photographer Also participated in simulated races and I'm impressed it's the closest to the real deal
Sick video! Digging into BeamNG suspension tuning is awesome. Try comparing the Dunekicker variants/tunes on different terrain types, desert/short course scenarios will really highlight the differences. Here's some more info if you wanna really dive into it: Dual spring rates are tricky to get right for sure. The goal for desert is as soft as possible on the springs, and let the shocks do the work. That's one reason why desert cars don't need much rebound is because the springs are very soft. Just stiff enough to hold the car up at ride height is a good starting point. A common misconception is that if the upper and lower springs are the same stiffness, than they will behave like one spring. What actually happens is both springs compress, so they move twice as much as one spring would. For example if you have two 100lb/in springs in tandem and you apply 100lbs of force, each spring will compress 1" making the combined rate 100lb/2in or 50lb/in. The formula for calculating the combined rate is: (primary * secondary) / (primary + secondary). This is where the slider stop ring comes in. When the spring divider hits the stop ring, the rate jumps from the soft combined rate to the stiffer rate of the lower spring. This keeps the suspension soft at droop with some added stiffness to help lift the chassis at bump. The goal is a smooth transition from soft to stiff and 2/3 on the upper rate vs the lower is a good starting point. Ride height is also good starting point for the crossover to happen. If the crossover is too low, the springs are too stiff, or there is too much preload the suspension will jack in turns and flip the car. The way coilovers and bypasses work together is also complicated, but you highlighted some important details in the video. Bypasses work by "bleeding" shock fluid around the piston and increasing the velocity that the piston has to move before the valving starts working. This does decrease the damping of the shock in the bypass zones, but not by making the valving softer. Each bypass tube has a metering valve that controls how much fluid it can flow from 0% to 100%. So when a tube is 80% open it means its flowing 80% of its capacity before the valving starts working, and the zones stack. For example, if the compression tubes are all open 25%, then there is 75% bypass in the short zone, 50% bypass in the mid zone, and 25% in the long zone. In terms of velocity, that means the piston has to travel 3 times as fast in the short zone as it does in the long zone to start building rate. That's why the car gets bouncy without coilover damping. The bypasses don't start working until they hit the velocity that you tune them for with the tube sliders. The coilovers control the wheels on chatter bumps and low speed movements like body roll and brake dive, then the bypasses take over on big bumps and get progressively stiffer as they compress. Bypasses are also important for controlling rebound because of the rate change in the springs. The suspension needs more rebound at bump to control all that energy. For desert, tune the suspension to use all of its travel on the roughest terrain without bottoming. Softer is better with just enough rebound to keep the car planted. Hope this helps and happy tuning!
Good info here!
@@JtmwTv thanks for this man you should do a video on this too! It’s still hard to wrap my head around but slowly sinking in. Every time I try to do this myself in the game I get frustrated with how many settings there are and the pluses and minuses to watch out for after each adjustment.
Thanks for the stiffnes tip it made my tune better
@worldwide_wes that's what's amazing about the game, all of those suspension tuning parameters are what you will find on a real truck.
@@collinkaufman2316 glad to help!
i didnt think i would watch the while video..but i got till the end.. really good explaination thanks for making this!
Man i wish we could have proper full length Baja trails without running into issues with map limitations in this game
I’m working on an Ivan Stewart TT mod for BeamNG. This information will greatly help understanding how coilovers and shocks work, especially since that will be needed to figure out how multiple shocks per axle will work, don’t know how that will help with torsion bars but that might be a different sort of thing. One truck Ivan Stewart drove used a single hybrid coilover shock per wheel with stiff eibach springs. Both trucks were full IFS/IRS setups
Happy to help! Join the discord and post your updates to your work. Lots of folks would be interested
that's what i was looking for.
Happy to do it dude! Good luck and let me know if you find your sweet spot!
@@JtmwTv MEN this baja suspension system was Black magic for me but your video show me the way to understand it!

Do we have a way of figuring out what the real life trophy trucks and ultra 4's are running for sag(aka ride height)? If we know a few parameters, we can get the sag dialed in more precisely. On a bike, you shoot for 20% - 30% sag(how far into the shock stroke does the suspension sit when the rider is on the bike). If we know how much actual stroke the bypasses and coilovers have, and then can figure out a ballpark of what the real life cars are running, we could set the cars in Beam up, for experimentation with tuning if nothing else. I say that because on bikes, sag is the foundation for which everything else is built on, the most important piece. At Fox, admittedly all suspension snobs, we set that very precisely with a machinists ruler, down to the millimeter/half millimeter. We would need a way to accurately measure this in beam, you can measure the shock shaft itself but the question is how
I write code for a living I’m sure you could write an extension to measure some some variables to obtain a sag measurement.
Desert cars are usually setup for around 60% up 40% down, and short course cars are 50/50 or less. Desert cars need to soak up big hits in the open desert without upsetting the chassis, while short course cars need cornering stability and traction. The Dunekicker TT1 and TT2 are desert tunes, the ST2 is a short course tune.
tysm for sharing your knowledge, sadly couldnt catch it live due to life, haha with your help, ive been able to begin understanding how suspension tuning works and make a fun build for mixed asphalt and mud use on jungle rock island its a stable steed over mud and dirt, and a controllable drift-mobile over low and high speed corners with the usage of a little bit of throttle theres just one thing ive been struggling a little and could use some pointers on. over mid speed corners (40-60ish kph) whilst gripping (esp on asphalt) it has a horrible tendency to roll and roll over completely. im guessing this is due to the high centre of gravity and softish suspension which lets the opposing front corner start lifting and the rear one sag a little too much, but its already at the edge of being easy to control over offroad. any tips on how to combat that? anyways, thanks for the guide
Yes I can help! Stiffen your rear sway bar!
Also thanks for watching!
@@JtmwTv tyy, that worked a charm before i was a bit hesitant of missmatching front and rear swaybars or putting the stiffness up too much as i thought it would heavily impact the rotation over more rocky/ditchy(?) terrain, but stiffening up the rear from 8k nms to about 30ish did the trick. now i can nyaoommmmm in piece(s) ❤❤
@@Zughiv happy to help!!
Do you play on controller and if so how did you set yours up? Would love to see a video about it bradah🤙🏾🇵🇼
Great vid but it would be nice if your face cam was on the right side of the screen somewhere and not over the tuning settings lol
Yep, thought about this after filming. Next time for sure!
What about a sheet showing final stats? I'm trying to follow but that cam makes it hard
Hey I downloaded the map and it's in my mods folder but it didn't apply to the game, I'm sure I'm missing something, any advice would be really appreciated, I'm a rookie on a computer
Ask in our general discord chat for help and someone should be able to get you setup.
@Jtmw TV I ended up figuring it out, awesome work on the map I love it, thanks for the reply
lol, no way, wanted to build a fun hopper for a beammp server
This should give you a good idea on how to tune for go-fast applications! I'll do a rock crawling tune video maybe this weekend, its almost the exact opposite as a fast desert tune!
you think you could do the same with building a rallye car in beamng on stream?
Same concepts apply but I'm not much of a rally guy. Might try it soon!
really cool video minus the fact that the cam is blocking all the info lmao
Not designed to give you exact measurements but teach how to.
I would have been nice to be able to see the settings, but your head is in the way. I have to be honest, this helped a bit but you dont give me a whole lot of confidence with how you jump around all over the place. Many things you said and the begining you contradicted in the midde. It ouwld be nice if you had your presentation more polished instead of giving me the feeling you were "learning on the go". Oh and the coller hight for dual rate springs do meatter and are most efective in the middle. All the way to the right you negate the helper, and all the way to the left you negate the main.
There are principals to follow in tuning but each setup is unique, this was more of a live walk through of how I do my tuning. Its been a while since I've walked through this video and I'm sure that in the middle I changed what was happening just for the sake of the demonstration. This was from a twitch live stream, not recorded to be a "presentation" style. You're welcome to take the reigns on that one.
