GrimmSpeed Mitsubishi Evo 8/9 Master Cylinder Brace

The master cylinder brace is made from 3/16 inch thick steel, which is a solid choice for this application. This brace is designed to reduce the flex that can happen in the firewall and master cylinder assembly under hard braking. When you're pushing the limits, especially on a track or during spirited driving, a flexible firewall can lead to a mushy or inconsistent brake pedal feel. By adding this brace, you're essentially creating a more solid connection between the master cylinder and the chassis, which helps to keep the pedal firm and predictable.

Installation involves bolting the brace to the strut tower and then connecting it to the master cylinder. It's a straightforward modification that makes a noticeable difference in how your brakes respond. You'll find that the pedal feels more solid and direct, giving you better control when you need it most. This is a popular upgrade for Evo owners looking to improve their braking performance without changing out the entire brake system.
