The GrimmSpeed master cylinder brace fits 2008 and later Subaru WRX, STi and Impreza models, plus 2008–2009 Legacy GT, and stiffens the master cylinder mounting area to reduce flex under heavy braking. By stabilizing the firewall mounting, the brace helps improve brake pedal feel and consistency during aggressive driving or track use. It installs as a direct-fit upgrade for the specified Subaru platforms.
