I have done my upgrade with E30 Calipers and 535 E12 master. This is a perfectly good setup, the best improvement is the 22mm master cylinder which keeps the pedal travel short with Volvo 4 piston calipers in front. If you want to write a "E21 Brake upgrade FAQ" some additional infos: - rear calipers can be used from E30 and E28 - rear caliper mounts must be used from E30 (and a little bit modified) - rear brake hoses fit from VW Golf II rear with ABS ATE part # 83.5104-0160.3 ... regards Horst from Austria '77 316 '80 323i with eta power '83 315 '89 320iC '95 A4 Tdi email: horst.apfelthaler@digital.com
