The Perrin Performance Transmission Mount Kit (PSP-DRV-151) is an essential drivetrain upgrade for Subaru enthusiasts seeking tighter, more precise shifting response and reduced powertrain movement. This mount kit replaces the soft, flex-prone OEM rubber mounts with a performance-tuned solution designed to handle the demands of spirited street driving, track use, and modified builds.

Key Features & Benefits

• Reduced Drivetrain Slop — Stiffer mount material minimizes transmission movement under load, delivering crisper, more mechanical gear changes with less vagueness through the shifter.
• Performance-Tuned Durometer — Engineered to strike the ideal balance between aggressive performance feel and daily drivability, without the harshness of solid metal mounts.
• Bolt-On Fitment — Designed as a direct OEM replacement with no cutting, fabricating, or permanent modification required, making installation straightforward for the home mechanic.
• Heavy-Duty Construction — Built with durable materials resistant to oil, heat, and the harsh underhood environment common to performance Subaru platforms.
• Improved Power Transfer — By limiting unwanted transmission flex, more of your engine's power is efficiently directed to the wheels rather than being absorbed by soft factory mounts.
• Perrin Quality & Engineering — Designed, developed, and tested by Perrin Performance — one of the most trusted names in the Subaru aftermarket industry for over two decades.
• Manual Transmission Specific — Purpose-built for manual gearbox applications, optimizing the driving experience for the enthusiast who demands full control of their Subaru.
