PERRIN 08-14 Subaru WRX/STI / 08-11 Impreza / 09-13 Forester XT Differential Subframe Lockdown Syst

Perrin Performance is well-known for making well-built suspension and drivetrain parts for Subaru vehicles. This Differential Subframe Lockdown System is designed to address a common issue in performance Subarus: drivetrain slop. When you accelerate or decelerate hard, the factory subframe can shift slightly, leading to a vague feeling and less precise power delivery. This kit aims to lock down that movement.

The system uses CNC-machined aluminum spacers and stainless steel hardware to fill the gaps in the factory subframe mounting points. By precisely fitting into these spaces, the Perrin lockdown system significantly reduces the unwanted movement of the differential and subframe assembly. This results in a more solid connection between the engine, transmission, and wheels, which you'll notice as improved throttle response and a more direct feel when shifting gears or applying power.

Installation involves placing the aluminum spacers between the subframe and the chassis. It's a straightforward bolt-on process that doesn't require welding or permanent modifications. Many owners find this a worthwhile addition when upgrading their drivetrain or suspension for a more connected and responsive driving experience.
