Description

Part #: 20-0773

Bolt-in master cylinder brace for the 2023+ Toyota GR Corolla

MIA's Description

It works by eliminating firewall flexing that occurs when the brake pedal is depressed, ensuring all energy is directed into hydraulic brake line pressure.

This brace installs on the strut tower, providing direct support and immediate response for harder braking. Its solid 1-piece billet aluminum construction ensures rigidity and prevents secondary flexing, while utilizing three mounting points for reinforcement.
