Since I was having trouble finding a set of 16" mesh wheels, I am converting to 5 lug and using some 16x7 BBS mesh wheels. They came factory on 90-92 Lincoln Mark VII LSC. They are cheap, and only weigh 17.5 pounds. They have a about a 20mm offset, but the Z31 turbo hubs are about the same. I have 5 Lug Z31 rotors, with 4x4 toyota 4 piston calipers in the front. Im going to use a 1" spacer for the back and redrill my stock brakes. I will post some pictures after they are done and mounted. (Should be a couple weeks )
