GrimmSpeed has provided a quality product that will eliminate the brake pedal flex in your vehicle. Some vehicles may have inherent master cylinder flex at the firewall which can take away from the feel and response of your brakes. The GrimmSpeed Master Cylinder Brace bolts up onto the chassis or firewall, and will fit in between the firewall and master cylinder providing.

The end result will be a solid brake feel, and better braking response, and all that excess pressure that otherwise, would be wasted in the firewall flex, will be used thoroughly in the braking system.

The GrimmSpeed Master Cylinder Brace has been crafted from CNC laser cut 12L14 with multi-point welded fabrication. This is a nuclear bomb surviving component with 5 factory mounting points, which is the most available from any brace. These are finished in a black powder-coated finish, and will restore that precision braking feeling

Not for the STI
NYstiGuy 28 days ago
Pain in the butt to get this installed, and after watching the Grimspeed video of installation you realize it was put on a WRX not a STI. The problem is the fuel lines are different in the STI then in the WRX so once installed you cannot connect back to the stock bracket. I called Grimspeed and was told that they only had a WRX when this brace was made... So why advertise for STI? Shame cause it is a great quality brace so unless you remove the stock brace and let your fuel lines dangle there, I suggest finding another brace.

Install was a little easier because I've put one of these on an older GR that I used to have. Brake feel is even better than it was when I install stainless steel lines. Would buy again if I got a third WRX.

Great Upgrade

So as everyone has stated, this is a total pain to install. Expect to have your hand and wrist chewed up at the end of the install. This really did firm up my brake pedal and made it much more consistent. I would recommend this to anyone that wants a firmer, more predictable brake feeling. The build quality is awesome! Very, very sturdy bracket. INSTALL TIP: Put tape on the bolt end before you place it in your socket. I used electrical tape. The makes the bolt a little tighter in the socket so it doesn't fall out when you're using your ratchet at weird angles. The hardest bolt for me was the very first bolt that you put in the bracket, but once I used the tape it made it so much easier. Hope this can help everyone out!

Pain in the a$$!
DSC4WRX 6 months ago
Installed on my '12 WRX with no other modifications to the oem brake system. The quality and construction of the GS product was remarkable. However, installing this piece was, for lack of a better phrase, a pain in the a$$. The top bolt hole, using one of the three small bolts, lined up perfectly with a brake line. That proved extremely difficult to remedy and caused many injuries and frustrations. The two bolt holes on the bottom of the obstructive brake line caused a lot of cuts and bruises as well; although, I figured out at the end that installing these two bolts from the bottom of the engine bay would have been easier. The two long bolts and fuel line bracket, hate those too. Specifically, the area of the two long bolts had little to no room to work with; threading these in, even with tools, was very difficult. Upon completion of the install, I had to rearrange the lower fuel line that was removed for this install. Testing out the brace, I was less than satisfied with the results. Considering how difficult it was to put in, I wanted to justify the purchase by telling myself the performance would be worth it; it was not. If there is a next time, I would not get a brake master cylinder brace and I would not recommended it. Too much work for little to no real effect. P.S. I spent about five hours on this project. Dropped the bolts many times too due to the lack of work space.

  • AnswerQ: Please Confirm Material  Ferny 9 months ago

    Can you please confirm the steel alloy that this brace is made from? Ledloy (12L14) is generally not suitable for applications requiring welding (high sulfur content causes the welds to have a habit of failing). Thanks.


    • A: Grimmspeed was able to respond to this inquiry and we will be removing the 12L14 label. They mentioned the labeling was outdated and had not been altered for a few years. They are constructed out of mild steel and then powdercoated and they have not had any issues with weld failure.

  • AnswerQ: light braking  Gamil 3 years ago

    Obviously this will have the greatest impact on heavy braking, how about on light braking? e.g. rush hour/around town?


    • A: The master cylinder brace helps prevent the firewall flex when the brake is pressed. Keeping it from flexing will help improve brake feel across the board. The further down the pedal is pressed the more affect this brace will have. :) Yes, it will help light braking as well.
