Replacement Brake Rotors

[ninjabones]

Bob and Darren, how would you interpret this rule?

B. Brake calipers and rotors must be as supplied by the factory for the year and type of vehicle.

C. Grooving/slotting/cross drilling of rotors is allowed.

 

Would you take this to mean that the dimensions of the rotor must remain the same, but that perhaps aftermarket rotors would be allowed?  Would fabrication of custom hats to accomodate aftermarket options (such as solid or slotted rotors) violate this rule?  Maybe this is a question best answered by Donna Amico.  And maybe it's not even worth asking as the cost of custom hats and custom rotors would likely not be offset by the added longevity.  I do remember a guy at VIR last year with a 993 that had some form of solid rotor setup on NB calipers.  Don't recall where he sourced them though.
