The Brembo kits come with caliper adapters, discs and bells, calipers, pads and braided stainless brake lines. The 4 piston 1B2.8022A runs $3300-3400 and the 6 piston 1M2.8001A runs $3600-3700.

Since the 4 piston caliper is basically the same as the stock 993 caliper, it is hard to swallow that amount of money for basically just some discs, pads and lines as the only improvement, particularly if you don't want Brembo pads and have braided stainless lines already.

Note though that the part number for the drilled disc and bell assembly given by my post above is 91.1542 L/R (left/right) and it would be nice to know what they cost alone.

I answered my cost question, a 355 X 32 disc set assembled with bobbins and springs, Brembo part 91.1542 is list price Euro 749 = $1034 each. Pricey but nice stuff.

A replacement disc without the bell is Euro 369 = $509
