Easy question: Does a 1997 C2S 100% have the same brakes as a 993TT?

 

Nope. C4S and TT do but not the C2S

 

I thought it was an option on the C2S to upgrade? (could be wrong here).

 

No, no Porsche option anyhow, C2S same as C2 and C4 although different colour calipers (C2 black, C4 silver)

 

A C2S, wonderful though it may be, was nothing more than a marketing exercise to get rid of leftover WB hips from the end of the Turbo production run.

A C2S is not much more than a C2 with wider hips and some other minor adjustments like the split grill, different gauges etc., whereas the C4S came with everything the Turbo did, i.e., chassis, brakes, WB, except for the Turbo.

 

C2S has wheel spacers as well to accommodate the larger body. Again only the TT and C4s have Red turbo brakes

 

The market seems to favor the lower production C2S pricewise. I always thought if you wanted a NA wide body in RWD you'd be better off getting a C4S and decoupling the front drive shaft, and get all the extras it came with, for less money.

 

That's certainly not the case in the UK - C4S tends to be more sought after and more expensive.

Incidentally, the brakes of the C4S are not lifted directly from the turbo model but rather follow the form of the four wheel-drive models with their hydraulic brake servo system as opposed to the 2 wheel drive models Vacuum servo. The discs and calipers/pads are taken from the turbo model, the rest is C4 with a further reduction in rear switch-over pressure from the C4's 45 bar to 40 bar for the C4S. The turbo is 55 bar. So there are subtle differences between turbo and 4S - not quite "a turbo, except for the turbo"

 

C2S also had an option available for 18" hollow twists (mine) so no spacers....
