Pressing Subaru brakes leaves a lot to be desired, especially when every inch counts in a race or when you are depending on them to save your life! The dramatic firewall flex is the source of this performance flaw in Subarus that we came to solve. Skipping the "standard bracket" that others have been making we engineered the most simple to install and best performing master cylinder brace on the market. The GrimmSpeed™ Master Cylinder Brace takes a beating and comes back for more! Crafted from hardcore CNC laser cut 12L14 with multi-point welded fabrication. It is the Abrams Tank of master cylinder braces touting 5 factory mounting points, the most available from any brace. Powdercoated black this brace will outlive your car and win you some style points to boot. Most importantly this brace kit will kill your wimpy pedal feel and give you the immediate and tight response that your performance car deserves and needs when you hit the track or rally. This brace will give you the confidence similar to that of SS braided brake lines with precision stopping. Not to mention street driving just got a whole lot more fun!

The reinvention of heavy duty, it's what you can expect from GrimmSpeed™

This is an example of the actual effect the GrimmSpeed brace has on a flexing master cylinder.

Huge difference in brake feel.

Even with just day to day driving, the pedal had a squishy feeling. It was the biggest issue I had with the car. I installed this brace and it's a night and day improvement in pedal feel. Wrestling around fuel lines was more difficult than expected but not impossible. Installation instructions are very descriptive and straight forward.

Worth it.

Put this on my 2011 Forester and felt the difference right away. The brace gives the pedal a much firmer feel as you apply the brakes. No more stepping on a sponge. Install was a bit tricky and definitely get the M6 tap that’s recommended. Take your time putting it in and you’ll really enjoy it - 100% worth it.
