Radium Brake Master Cylinder Brace 2015+ Subaru WRX and STI

Radium Master Cylinder Brace | 2015+ Subaru WRX and WRX STI (20-0255)

Regular price $89.95 USD $84.45 USD

Manufacturer: Radium

SKU: rad20-0255


The Radium Master Cylinder Brace for the 2015+ WRX and STI mounts to pre-existing holes in the engine bay and supports the master cylinder for improved pedal feel and less firewall flex. This is a simple install (30 minutes or less) and can be easily installed/uninstalled without a trace.

Because the master cylinder flexes in a curved path, a specially designed CNC machined foot contacts the master cylinder to counteract the arc movement. Preload is adjusted with the anodized aluminum green bolt then locked in place with the stainless steel jam nut.

Vehicle Applications:
  • Subaru WRX [VAG] (2015, 2016, 2017, 2018, 2019)
  • Subaru WRX STI [VAB] (2015, 2016, 2017, 2018, 2019)
