Ohhh rear conversions Now dont get me going, but whilst we are here and sharing a little knowledge then...

Compbrake do a rear caliper the "R2"

I can tell you that this is EXACTLY the same caliper that is fitted to most of the Audi range (The TT and TT Convertables for deffo)

If you walked into an Audi dealer they would cost you on average £186 each (maybe plus vat).

Exactly the same caliper with Compbrake milled on to the side will set you back around £65

How can the dealer justify selling the EXACT same thing for that price ??
Its because they do and people are willing to pay it.

Same as for AP's IMHO.

Anyway so as not to upset people can you email/phone them direct please details are on www.compbrake.co.uk and ask the technical questions yourself

If once your sorted and you need further help give me a shout
