993 C2 calipers on 964 C2?

[HAB]

How much work involved to get them to fit? (hopefully not much)

993 calipers are from a '96. 964 is a '90, hence small calipers on the rear.

Cheers!

Pretty straightforward - lots on Rennlist 964 forum about this. The rear calipers are a straight bolt-on replacement (using standard 964 discs). For the fronts you will need a caliper mounting adapter (same as the one for Big Red calipers), and different discs (928S4 I think). Do a search on Rennlist for '993 brake upgrade'.

Thanks for that, I might leave the front for now, and replace the back. I'm thinking the 944S2/68 used the same calipers as the 4 pots on the 964C4,wonder if they are a straight swap also?

Yep, pretty sure they are the same as the 964C4. If you go both front and rear 993 set up it is worth changing to the the proportioning valve from the RS or the Turbo (964) to take advantage of the extra rear braking capacity. I did this on my old '90 C2 and it was a very worthwhile upgrade. Go for stainless hoses, decent fluid (Super Blue or SRF) and good pads and you will never suffer from brake fade. You're pretty much going for the full RS set up, only the 928S4 front disc is marginally smaller than the RS / Turbo disc. The RS / 964 Turbo caliper (non-big red) has slightly longer mounting lugs to allow the use of the bigger turbo disc although the main body of the caliper is identical and the pads the same as the 993 item. It took me ages to figure that out !
