    R/S Alignment

    I have an R frame that is being set up for street (and mostly) track days. Not racing
    After reading a few posts on it, here is what I'm planning on. Let me know if you have suggestions.
    Basic info:
    STI drive train, S suspension holes, TW 200 tires; spring set up is 400# front, 300# rear
    Bump steer kit with ~30mm drop (might need more)

    Front
    Caster: appears to be 4.7*, hoping to get close to 5*
    Camber: -1.5*
    Toe: 1/16

    Rear
    Camber: -1.5-2.0*
    Toe: 1/4 - 5/16"

    Are running any significant aero, rear wing, front splitter, front canards, etc...? If so those spring rates are too low. On the front, I assume you mean +1/16 toe out. If so that will make the car quite darty on the street, better to run -1/16 toe in. Same with the rear, maybe try zero at first and see if you need any toe in. The streets are full of pot holes, ruts, crowning, speed bumps etc..

    Yeah, a pretty big omission- no aero at all at this point
    and yeah, I'm using toe as toe-in

    My set up with 350# front and 275# rear springs, S suspension on an S chassis, front splitter and canards, rear diffuser and bump steer close to zero is:
    Front toe 1/16 each side, caster 4.6*, camber -0.75*
    Rear toe 1/8 each side, camber -0.8*

    Car is street driven and drives very well.
