Getting a set of brembos would be well cheap, but where would i get the mounting kit from?
As for the mounting kit any good engineering firm would knock one up easily.
I'm lucky and have all the machining equipment, lathe, milling machine etc.What people must remember is if used very hard such as on track you need to go bigger.
The number of pots a caliper has isnt the be all of brakes, by fitting 4 pots to std size discs you will not gain much as the heat build up will still be similar, you will gain slightly due to most 4 pots being an aluminium alloy construction though.
I would suggest something like Porsche brembos (huge) and 315 x 28mm discs IMHO this is a bullet proof setup.
