I was wondering if you can install Stoptech 328mm X 28mm 2 piece rotors and continue to use the stock calipers?

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi, I was wondering if you can install Stoptech 328mm X 28mm 2 piece rotors and continue to use the stock calipers? Does anyone know the stock rotor size for a C2? I believe they are 317mm x ?mm Does going to a wider/maybe thicker rotor affect pad size? My main goal is to reduce weight and go slotted rotors. I have the Stoptech rotors from a parts collection and would rather use them if possible. My other option is to buy the performance friction 2 piece direct replacement for 996 C2. Thanks! PS - i have searched for hours on rotor sizes, did not find much useful info. thanks again.

POST 2Original post

Proper rotor size is 318 x 28 mm pfc rotor with hat is p/n 318.067.87and 318.067.88

POST 3Original post

You can not use oversize rotors on any car. Rotor size is specific to the caliper.

POST 4Original post

We carry OEM replacement slotted rotors that fit the C2 much cheaper the the PFC 2 piece units. If you have the Stoptech units and really want to fit them on your car.... Confirm this first... Is the offset the same as OEM? If so, we can make you a spacer (that would fit under your calipers)and supply longer bolts that permit your Stoptech units to work.
