    Bumpsteer in 04 WRX

    Hi to all,

    I changed my suspension to TEIN coilovers, and the car was lowered 1.5 inches. Now, when I drive over a bump or pothole, the steering wheel turns on the direction of the bump (left or right). I mentioned this to a buddy and he told me that the problem was probably bumpsteer. Does anybody know what do I have to do to correct this problem in my beloved subie??

    There isn't anything that can be done to correct bumpsteer, it is a function of the suspension geometry. You could raise the car back up, but that's about it.

    you could look into Whitelines RCA kit, its about 175 bucks, and it raises the roll center and CG of the car. its basically designed to raise both of these because of how the camber curves and such of the mcphearson strut on the WRX is. when you lower it it basically puts the steering arms at such an angle that they move the steering wheel under bumps, hence bumpsteer. so the whiteline RCA should at least help if not fix your problem, its designed to do just that! raising it a little wouldnt hurt either
