LADA PROTO
Front suspension is double wishbone on Protlum coilovers.
CAD designed to minimize bump steer and optimize caster, chamber,
rool center and ackermann angle.
Suspension parts are made from 4130 chromoly and aluminum.

Our budget is limited so we need to design, test and produce rally car parts on our own. Unfortunately, we cannot manufacture everything so your help would be greatly appreciated.

👍
Are you going to fit a dust cap on the back of that stub axle?
Yes we did
What percentage ‘Ackerman’ did you use on the steering geometry ? You are doing very good, solid work here 😃
We use 26 % and it feels good
@@RallyJunkies ok I was thinking for a rally car maybe 50% but if it feels good 👍 that’s enough 😀
@@DMJ52 Yes, I believe that it is enough because slip angle of outside tyre.
@@RallyJunkies Yes I agree. I wish you success in the future.
What bearings you use for the front wheels ?
We use VW golf 2 hub and Vento bearings.
Hola de q país son hacen esas piezas por encargo ?
Croatia, EU
You need to secure the split pin again.
Да уж..... Кулак на чпу..... Это сильно
Thanks !!
Hi. Tell me please what springs (kg/sm) you used on front and rear?
Hello, it is not a simple answer. We use some 150 kg/cm but our motion ratio is about 0.6 so this gives equivalent of 51 kg/cm on mcphearson suspension. If I need I can give you math and geometry explanation.
@@RallyJunkies I`ve got stock geometry and was thinking what suspension i need.. Now I have 60kg sm on front and 22kg sm rear, but i don`t know hardness springs on the rear from Vaz parts((( there are also for front 75kg(niva) and 93kg (chevrolet niva).Do You know any springs for stock geometry?
I am sorry I did not calculate spring rates for stock geometry. I think that some 60 - 70 kg should be enough. On rear end I would have some 40 kg maybe 45...
@@RallyJunkies thanks for unswer ))

Shock absorbers are custom made Protlum Top-race. You can se more info on website: www.protlum.eu

Гайка на рулевой тяги кулака неправильно законтрена, контровка не должна болтаться соплей. Контровка должно пройти гайку, болт и усами разойтись усами вдоль граней гайки.
Adjustable coilovers?
Yes they have 3 way of adjustment: 1. Highspeed compression damping 2. Lowspeed compression damping 3. Rebound damping adjustment You can find more details on page: www.protlum.eu/web/en/2-Products.html#top_race
@@RallyJunkies and height?
@@abdallahturk6113 yes, and height can be adjusted
Can I buy them?
Yes, we produce custom parts also.
Lada is so s*"t car you should not even spray paint in coz waste of money.
Lada is perfect, you only need few modifications :-))
@@RallyJunkies "few"..
