I have been looking everywhere without any luck. Does anyone know if the 997 Turbo 6 piston front calipers can be fitted to a base model C2?
There seems to be a brembo set, but would like to stick with OEM

 

I have larger turbo front and rear calipers on my C2S. The front 6-piston versions fit using the longer turbo caliper bolts. The dust shields also need to be modified (easily done with tin snips) or replaced with the turbo version too. The only other issue is the hard brake line connecting the caliper to the front upright. The stock C2S version was too short and the turbo version did not mate up to the upright mounting location. You can buy a short straight brake line at any auto parts store and custom bend it to fit. Overall the install was a 7 out of 10 on the difficulty scale. Other than the brake line everything else was no more difficult than swapping out calipers & rotors.

Obviously you need turbo rotors and brake pads too...

 

Thanks for the info! I have done a full brake job myself so I am confident I can tackle the task. My biggest concern is the caliper itself not bolting to the wheel carrier. There is a similar thread about PCCP brakes, which I know it is a different topic, but they do mention the something along the lines that the mounting bolts are not at the same distance. They also mention the C2S calipers don't fit the C2. Unfortunately, a lot of people talk a lot without know for sure. Just wonder if anyone has done the conversion. I don't want to but the calipers to find out they don't fit.

 

Suncoast sells the conversion kit. I would only use the front calipers as the rears have bigger piston area and will affect the brake bias. The piston area of the 6 pot is the same of the 4 pots you have.
