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 discs are extremely expensive at 1.1 mil yen per disc. TOP SECRET has developed steel brake discs to replace the genuine carbon discs
so that drivers can enjoy the new brake discs more easily. For customers who want to install "yellow calipers" on their GT-Rs other than those with yellow calipers
we recommend this set for those who want to do so on a budget.
