Says he is running a Wilwood SL6 Caliper and a C5 rotor under that 17 inch wheel. I want to know how he did it.

I contacted the last owner, he bought the car the way it is.

C5 rotors used to crack all the time on track talking to the guys that ran them. I run C6 rotors with a FSL4i caliper, which takes the same pad as the SL6 if I remember right. I use C5 Z06 fronts though, not sure how they compare to the TA 5-spokes.

C5(all)-C6 (base) rotor=dimensionally the same.


FSL Caliper is lug mount

SL6 Radial mount

I don't think a 14 inch rotor will fit under a 17 inch wheel. I have the 13.06 rotor under a ZR1 wheel with the SL6 caliper, can't go much bigger.

Dimensionally the same, yes. Constructed the same, no. C5 rotors would crack within 1-2 days, C6 rotors will last 5-7 weekends.

As far as 14" brakes under a 17" wheel, it can be done, but not likely with a SL6 (or any Wilwood with a bridge bolt) or an OEM wheel.

Also, on the original picture, the car may have SL6s, but they aren't legal on a CMC car. Rules say has to be a 4-piston caliper on the front.
