Big Brake Kit 355x32 Front / 355x28 Rear – Toyota GR Yaris & GR Corolla
 
Stop faster. Drive harder.

The Ichiban Engineering GR Yaris Big Brake Kit delivers uncompromising braking performance for both the Toyota GR Yaris and GR Corolla platforms. Designed entirely in-house, this system offers race-proven stopping power with precision fitment and OEM-like reliability.
 
Each kit includes 6-piston front calipers paired with 4-piston rear calipers, gripping massive 355mm two-piece rotors. The rotors feature a 7075-T6 aluminum hat for reduced unsprung weight, improved heat dissipation, and optimal strength under repeated high-load braking.
 
The front discs measure 355x32mm, while the rear setup uses 355x28mm rotors for ideal brake bias and fade resistance. The system is engineered for balanced pedal feel, shorter stopping distances, and consistent braking even during extended track sessions.
 
Every component has been precision-modeled, tested, and machined to fit perfectly on both the GR Yaris and GR Corolla without unnecessary modifications. However, aftermarket wheels with larger spoke clearance may be required.

Custom finishes are available for both calipers and brackets — choose your color from the drop-down menu above to match your build perfectly.
