Race Technologies Brembo GTR BBK - Rear for 2022+ Subaru WRX

Race Technologies Brembo GT-R Rear Big Brake Kit (Type 3)

2022+ Subaru WRX (VB) 

The Race Technologies Brembo GT-R Rear Big Brake Kit is the highest-tier rear braking system in Brembo’s GT-R lineup, engineered for drivers who want true motorsport-grade performance, maximum thermal capacity, and consistent braking under extreme conditions. Built around 4-piston billet aluminum monobloc calipers and large 345mm two-piece floating rotors, this system delivers sharp pedal response, improved stability under repeated hard braking, and balanced braking performance when paired with a front GT or GT-R kit.

Designed specifically for aggressive street use, canyon driving, autocross, and full track environments, the GT-R rear kit prioritizes stiffness, heat management, and reduced unsprung mass. The complete kit is pre-assembled and includes all mounting hardware, stainless steel brake lines, and high-performance pads for a direct bolt-on upgrade (vehicle compatibility dependent on parking brake configuration).

Why Choose the GT-R Rear Kit?

The GT-R rear system is designed to eliminate brake fade and inconsistency during sustained high-load braking. Compared to lower GT systems, it offers increased stiffness, better heat control, and a more direct pedal feel that stays consistent even after repeated hard stops. When paired with a GT-R front kit, it creates a fully balanced, motorsport-capable braking system for the VB WRX.

This is not just an upgrade for looks or light performance driving—it’s a serious braking system built for drivers who regularly push their cars hard.
