The MY22 GT-R NISMO and GT-R T-spec use so-called stock "yellow calipers" to accommodate large diameter carbon brake discs. Stock carbon rotors are extremely expensive at 1,100,000 yen/piece. TOP SECRET has developed steel brake discs to replace the stock carbon discs so that drivers can enjoy the car more easily. This brake disc set is recommended for use on the MY22 GT-R NISMO and T-spec, as well as for customers who want to install "yellow calipers" on earlier GT-Rs, while keeping the budget low. Special brake pads (sold separately) compatible with these steel discs are also available.
