PERRIN 15-21 Subaru WRX & STI / 12-25 Impreza / 24-25 Crosstrek Differential Lockdown System

With this Perrin Differential Lockdown System, you get the necessary components to brace your rear differential. This setup is designed to increase the rigidity of your Subaru's drivetrain, which can lead to sharper and more responsive throttle control. It's a well-built addition for drivers looking to feel a more connected feel from their car's power delivery.

The main idea behind this lockdown system is to reduce the amount of flex and movement in the rear differential under load. By minimizing this unwanted motion, power is transferred more directly to the wheels, making your acceleration feel more immediate. It's a popular modification for those who want to improve the overall feel and performance of their Subaru's drivetrain, especially during spirited driving or track use.
