So I have a 100% complete Z32 brake set up that I had been planning on putting on my car. Everything is new and by complete I mean also BMC, brake lines and ebrake adapter plate, etc. That was my plan for years and I was about to get into it then I came up on a sick used Rotora front BBK
http://www.hopupracing.com/rofr4332crdr1.html The Rotora kit is made to be used with stock BMC as is a direct bolt on like the Z32. It's in great condition with new pads. So I'm hoping to get lucky enough to find someone here who's actually felt both set ups. The Rotora set up would actually be alot cheaper cuz I would sell the Z32 set up, but the only downfall I see is massive front brakes and weenie rear brakes, but I suppose I could always do Z32 rear brakes. Wish there was a better s13 rear brake option that was bolt on but AFAIK Z32 is the only rear upgrade option for our cars.
