Hi,

I got my hands on 4-piston calipers from Hirsch/Brembo and am looking for aftermarket discs.

I know what brake pads will fit and will go for EBC Red Stuff DP31110C, which are basically the same as was fitted to Ferrari F40, but am lost as far as disc are concerned. Not sure which ones will fit. Searching the forums there seems to be conflicting information about the diameter of the discs that fit these calipers. Anyone know which one out of below is correct?

332 x 30
332 x 28
330 x 32

Any ideas which brand makes these discs and what model they are?
