ok i've got 15*8.5 centerline warriors with 4.5" backspacing on my 87 gt. i got around the tire rub i believe but i'm getting a ticking sound thats bout to drive me nuts. seems like i read someplace that its caused by the caliper bolts. thinking bout grinding them down a little and see if that helps. it only makes the sound when i cut the wheels either direction. any ideas?
