GrimmSpeed's 75A street transmission mount is a direct-fit replacement for Subaru manual transmissions: compatible with 2004–2021 STI (6MT) and 2002–2024 WRX (5MT/6MT). The 75A durometer compound offers a firmer mount than stock rubber while remaining intended for street use, giving a balance of drivetrain control and daily drivability for these Subaru models.
