I want, as an interim measure, to upgrade to BIG RED spec brakes at the front with 322mm discs.
The calipers from 993TT should bolt straight on. The problem is front discs.
If I use the discs from a 993TT, I will need 5mm adaptors.
However, I believe that the 911c2 Turbo uses the same size discs as the 928GTS (difference is that GTS are solid face, 911c2 are drill / cast hole ventilated), and would not require spacers, but rather be a direct fitment.
I appreciate that
a) I could gain up to 4 lbs unsprung weight using these bigger cast discs rather than the separate aluminium spacer route.
b) I will have to swap the unions and crossover pipe to correct orientation because of leading vs trailing orientation.
c) I also have larger than 16" rims, so clearance won' t be a problem.
Has anyone else done this yet ?
