Solid as a rock, the Perrin Performance master cylinder brace quickly solves a long-time Subaru braking issue: flexing of the firewall under hard braking.  Created from 6061 aluminum, the brace adds significant support as well as some additional under the hood eye candy as it's anodized black. 


*Easy Upgrade* The Perrin master cylinder brace is a quick and affordable upgrade that adds positive brake feel and increased style under the hood.  The Perrin master cylinder brace bolts from the brake master cylinder to the driver-side shock tower to give you a firm pedal feel.
