Perrin Performance


PERRIN Master Cylinder Support for Subaru 2015+ WRX/STI

Neon Yellow

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.

*Easy Upgrade* 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 to give you a firm pedal feel.

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