So i have the c6 zo6 brake on my 79z and with those you need to spend alote of money on wheels so they fit O.K so thats what i did talked to alote of ppl and went with the Forgelines after putting the front end together I found out that the top to ribs on the caliper hit the bolts on the wheels all this money and need to trim the top of the calipers to make them fit. Just wanted to let you all know about this so you dont get smacked in the face like i did
