GT1R Small Rear Brake Kit for Nissan GT-R R35 – 15" Wheel Fitment

The GT1R Small Rear Brake Kit lets the Nissan GT-R R35 run 15" rear wheels. The factory rear Brembo setup is too large to fit inside a 15" wheel. On a drag build that means the car can’t run the smaller-diameter wheels and taller-sidewall drag radials that help launch traction and consistency.

This is a complete rear brake conversion, not just a caliper swap. The kit comes with its own rear knuckles, built to mount the smaller caliper and rotor package. It also includes the backing plates, parking brake shoes, braided stainless steel brake lines, extended wheel studs and mounting hardware, so everything is engineered to work together. The compact rotors and calipers also cut rotating and unsprung mass at the rear axle, which helps on a car built for the quarter mile.

Why Run 15" Rear Wheels on an R35?
A 15" wheel takes a drag radial with a taller sidewall. The sidewall flexes and wrinkles on launch, which puts more of the tire on the track and helps the car hook harder and more repeatably. This kit is what makes that tire and wheel combination possible on a GT-R.

Fitment Note:
Check that your wheel’s offset and inner barrel profile clear the caliper before you order. The Subzero Motorsport team can confirm fitment for your wheel and tire package and install the kit as part of a full drag setup.
