Perrin Master Cylinder Brace - 15-21 WRX/STI

Solid as a rock, the PERRIN Performance Master Cylinder Support quickly solves a long-time Subaru braking issue: flexing of the firewall under hard braking.

The PERRIN Master Cylinder Stiffi is a quick and affordable upgrade that adds positive brake feel and increased style under the hood. The PERRIN Master Cylinder Support bolts from the brake master cylinder to the driver-side shock tower as a brace to give you a firm pedal feel.

The PERRIN Performance Master Cylinder STIFFI is machined from 6061 billet aluminum for extreme stiffness.

Anodized black with a bold PERRIN logo to dress up the engine bay & show off to your friends.
