Perrin PSP-DRV-151 Manual Transmission Mount for Subaru WRX STI Forester

Vehicle Fitment

• 2002-2026 Subaru WRX, manual transmission
• 2004-2021 Subaru STI, manual transmission
• 2013-2019 Subaru Crosstrek, manual transmission
• 2004-2008 Subaru Forester XT, manual transmission
• 2004-2011 Subaru Forester (naturally aspirated), manual transmission
• 2005-2009 Subaru Legacy GT / Outback XT, manual transmission

Fitment Notes

• Manual transmission only - automatic transmission applications are not supported
• Because this mount is stiffer than the factory transmission mount, expect increased NVH (noise, vibration, harshness) compared to stock

Features

• Reduces drivetrain movement under hard acceleration, deceleration, and cornering for a more connected feel
• Delivers more efficient power transfer to the ground for more accurate launches in drag racing and autocross
• Virtually eliminates shifter wobble and mis-shifts caused by transmission movement over road imperfections
• Custom large-diameter 62A/70A durometer polyurethane bushings resist breakdown and outlast OEM rubber mounts
• CNC-machined 6061-T6 aluminum mount housings paired with a formed, powder-coated steel base plate
• Proper mechanical interlock design, unlike the OEM mount's bonded rubber and small retention tabs
• Reduces risk of the transmission mount failing and disconnecting the transmission from the chassis under extreme conditions

Specifications

• Bushing material: Polyurethane (62A/70A durometer)
• Mount housing material: CNC-machined 6061-T6 aluminum
• Base plate: Formed, powder-coated steel
• Transmission compatibility: Manual only

Included Components

• 1x PERRIN Manual Transmission Mount Kit (PSP-DRV-151)

Product Description

The PERRIN PSP-DRV-151 Transmission Mount Kit is a performance drivetrain upgrade for manual-transmission Subaru owners who want a tighter, more mechanical shifting feel and reduced drivetrain movement under load. By replacing the soft, flex-prone OEM rubber mount with a stiffer, purpose-built design, this kit minimizes transmission movement during hard acceleration, deceleration, and cornering - translating to more efficient power transfer and more consistent, repeatable launches in drag racing and autocross.

At the core of the mount are custom, large-diameter polyurethane bushings pressed into CNC-machined 6061-T6 aluminum housings, held in place with large bolts and a thick, powder-coated steel base plate. This construction virtually eliminates the shifter wobble and mis-shifts that stock owners often notice over rough roads, while a proper mechanical interlock design addresses a real weakness in the factory mount - where bonded rubber and small retention tabs can eventually fail and let the transmission disconnect from the chassis.

This mount kit suits manual-transmission Subaru owners across the WRX, STI, Crosstrek, Forester XT, Forester, and Legacy GT/Outback XT lineup who want more precise shifting feel for spirited street driving, track days, or drag/autocross competition. Because the mount is significantly stiffer than stock, owners should expect increased NVH compared to the factory setup - a tradeoff most performance-focused drivers find well worth the improved drivetrain connection.
