Ive been looking for a few hours now and i cant find what im looking for anywhere. Something i need to get out of the way, im not going to use toyota brakes... thats not what im looking for. What i would like to do is put z32 (or z31 5 lug) wheel hub, rotars, and calipers on my 1981 280zx turbo. My thought and question is, can i take off my 4 lug wheel hub and bolt on a z32 5 lug hub, then bolt directly on z32 4 piston stock brakes. I plan on doing 5 lug 15 inch wheels so I should have clearance but i dont know if everything will line up. I dont want to spend more than $500 on the brake conversion but I can go higher if i need to.
