Thread: New suspension setup

  1. #1

    Default New suspension setup

    I'm building a Subaru WRX STI rally car and need help with proper suspension set up! I am planning to run hot bits adjustable rally coil over setup. I need help with Valve rates. What is a good base line setup? What about alignment? What should I run in the way of caster and camber? Any help would be appreciated!

    alignment ... I would try about -1.5 front -1 rear , with zero toe out as your base. you can go with a little bit more neg camber if the event roads are very smooth.

    that's the little i know...

    My ideal alignment specs (but every event things get a bit rack around...)

    F = -1.5 to -2.0 camber, zero toe, 3.5 degrees of caster
    R = -.05 to -1.0 camber, .05 toe out

    What hot bits kit are you using? DT1? DT2? RSI?

    Toe out in the rear is going to make things tail-happy (so I wouldn't start there). A little toe in for the rear will increase straight line high-speed stability.

    Start at 0 toe all around and see what you want after that.

    I go with toe in, stability = speed in rally. Toe out will be too jumpy. I had toe out in the rear for sno*drift (didn't align the car) and I had a big spin at 80mph.

    My question about the HotBits, if you don't have the inverted shocks, you'll most likely bend them. Not saying they won't work, I co-drove for a guy at BRS who used non-inverted HotBits. Get some inverted if you can down the road.

    Yes, and that set was just fixed from having bent both rears...

    Haven't decided for sure but I'm looking at either the dt2's or RSI

    Thanks for the alignment suggestions as well! All very informative and should give a good baseline to start with!
