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.

Works Great!

Installing as a novice it was a bit of a pain it took me about an hour total but works as it should and helped with the pedal feel on my 2012 WRX.

bitter sweet

Reduces Flex and give tighter feels on breaks and improved more. However, I did not feel much of drastic change compared to when I installed SS break line. Install... Steps are very simple and easy level.... BUT for 2011 WRX, it was very painful for the installation. Fuel line was covering the screw area and very tight room to work on. Had to yank (Stress out) bit of fuel line to get an access which I had concern with, but they are ok. Overall I love it, and I love the looks in the bay as well.
