Brake Master Cylinder Brace

• 2023–2026 Toyota | GR Corolla

The Toyota GR Corolla platforms suffer from a common issue in streetcars, brake master cylinder flex.  This is due to the thin sheet metal in the firewall flexing while pressing on the brake pedal.  While on track and on the street, this leads to a vague feeling in the brake pedal.   We developed this kit to fix the issue by dramatically reducing this movement.

This is a great addition to your Toyota GR Corolla if you track the car or want an improved brake pedal feel.  We saw a reduction in deflection of ~63% with the use of our brace compared to OEM.
