so does anyone know the actual difference between the brakes on the 997 base and the 997S - besides being red? thanks

 

caliper size huge difference perforamnce wise

 

Do both sets have the same number of pistons as well?

 

Besides the red:

- Both S and non-S are 4 pistons calipers. They do not use the same pads so you have more pad surface on the S model - the S calipers are beefier and can presumable apply more force / dissipate more heat.

- The discs are the same diameter but they are thicker on the S model. Better heat dissipation, may last longer.

- I believe you cannot change the pads without removing the calipers on the non-S brakes. That could be a pain if you track and want to swap pads yourself.
