thanks for the replies.
she has prokits with koni SP3s. the fronts are one perch lower and the rears are on the top perch because of the weight of her system. i'm guessing the front is dropped around 1.75-2" and the rear is 1.5-1.75". she's looking at the one piece Racing Hart CRs which are 18x7.5 with +42 offset. is rubbing more likely because of her drop? or should we look for a wheel with +45 offset? i got the specs here:
