- Best Price (800-636-0854) sells Brembo rotors that they will cross-drill or add slots to for an extra fee
- Wolf Sport (800-342-8669) also has drilled rotors

The 90Q20V has weird front brakes. The rotors are 256mm like the regular 90, but it is NOT the same rotor! The offset is different. Because the demand for these special rotors is low, it's tough to find replacements, and the dealer will charge $120 -- $140 EACH! The Audi P/N is 893 615 301A.
The overall diameter of the "small" rotors is 256mm as opposed to 276mm (found on the Coupes) and the center hole is 68mm with a 30mm "tophat" (offset from the rotor face). The portion between the rotor face and top hat is NOT vented in the joint. I'm including this info because most of the books on the car are WRONG or confusing at best. Best Price in Ottawa Canada (800-636-0854) carries high quality rotors (blank, drilled or slotted for an extra fee) that will fit this car for around $120 per pair. Ask for P/N EUR #AU258. IMPEX (800-736-3550) also carries suitable rotors. They use the Audi P/N.
See below for details about upgrading the 90Q20V to the 276mm rotors and G60 calipers that came stock on the CQ.
