james how you doing?
only just saw this thread, still not got the 360 fully tuned yet, have junked the old 16v fuel inj and ign setup and now got the omex on and barely running, just waiting for some money so i can get the car tuned on the rolling road.
Anyway yup the brakes etc, the vw corrado setup was fairly easy, and its the four pot wilwood dynalites that help stop more than anything.
the clutch i know you can get a ap racing clutch for ours, saw one on a b230 at auto sport 2 years ago here a linky to a pic i took
