TOP SECRET’s slotted 400mm rear 2-piece steel rotors provide a serviceable, lower-cost replacement for carbon-ceramic rear discs on 4BA R35 GT-R NISMO and T-spec models with yellow calipers. They retain the large-rotor sizing and use a two-piece slotted design aimed at stability under heat and repeated hard stops.
Sold as a pair
On 4BA GT-R NISMO and T-spec models, the yellow calipers are matched to large carbon-ceramic rotors, and the replacement cost is high enough that it can change how often you drive the car hard. TOP SECRET’s slotted 400mm rear 2-piece steel rotors are aimed at owners who want a practical steel alternative that works with the factory carbon-brake rear caliper package, whether you are moving away from carbon for budget reasons or building a yellow-caliper setup and want a more serviceable rotor option. The 400mm diameter maintains the correct large-rotor sizing for these cars, and the two-piece, slotted design is focused on staying stable under heat and repeated high-speed stops. It is a straightforward way to keep the GT-R’s braking system usable for real street miles and spirited driving without the ongoing expense of carbon rotors.
TOP SECRET is a Japan-based GT-R specialist known for developing parts around real repeated-load driving, where heat and service cost become the limiting factors. They tend to focus on solutions that preserve factory geometry and function while making the car easier to run hard, which is exactly the point of a steel rotor option for a carbon-brake-equipped R35. On brake parts specifically, their designs usually prioritize diameter, cooling, and compatibility with OEM calipers so pedal feel and balance stay familiar. For NISMO and T-spec owners, that approach provides a way to keep the yellow-caliper, large-rotor setup intact while choosing a rotor you can replace without the carbon-ceramic price tag.
