Thread: So the new ICM helped but not much could it be my CPS

yes, like a 2000. you need the caliper, the caliper brackets and bolts, the brake lines and new rotors.

and then you need some sleeves to put in the knuckle so the f body caliper bracket bolts center up, or drill and tap the f body brackets to use the stock caliper bracket bolts, the stock bolts are fatter then the f bodys.

dont the impalas have the better brakes? then the gp and regals? id look into that, if they are already a larger disk running what you have they may be almost as good. with out all the swapping.
