Ok guys, i've had my cts-v brakes for a year and a half now, and they are still not on the car! I WILL be doing them over the winter! but my concern is how do i know what size spacer to run? i have 18x10" ccw 505a wheels up front... (i dont know the offset as i bought the wheels used) i measured the spokes to the stock caliper and it measures .75" i have read up on the swap, that you need 1.25" of clearance from the stock caliper to the spokes in order for the calipers to clear...
SO, does this mean i need a 1/2" spacer to clear the calipers??
if thats correct, do you guys have a spacer that suits my needs with a part number so i can finally get this done!
Thanks!
