Pressing the Subaru/Scion 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 firewall flex is the source of this performance flaw in Subaru's and Scions that we came to solve. 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. 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!


Solving annoying OEM issues, it's what you can expect from GrimmSpeed™

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

Good buy

Unit bolts up easy and tight. Surface area of force distribution cap is far larger than other similar products, this is good design. I don’t do hard braking often, as I mostly DD, but the few times I’ve done it car’s performed exactly as it should have, noticeably better than before.

Easy to install, immediately noticeable when braking especially harder braking. One thing to note: in the install guide it mentions removing a sticker over the hole closest to master cylinder. On my '16, there was a bracket there instead with a plastic clip that was holding a bundle of wires together. The brace does not support the continued use of said bracket. Not a big deal, just something to note.
