Review WHITELINE Rear Differential Mounts Positive Power Kit fits IMPREZA WRX STI 2008

The Whiteline WHLKDT906 08 Impreza WRX STI Rear Differential Mounts Power Kit is an essential upgrade for Subaru Impreza WRX and STI models from 2008, designed to enhance the performance and durability of the vehicle's rear differential mounting system. This power kit is manufactured by Whiteline, a reputable automotive engineering company known for its high-performance suspension and chassis components.

The stock differential mounts on the Impreza WRX and STI are made of rubber, which can degrade over time and allow differential movement during aggressive driving. This can lead to power loss, reduced handling, and potentially damage other components. The Whiteline Power Kit addresses this issue by replacing the rubber mounts with stronger, stiffer, and more durable polyurethane mounts.

The kit includes four mounts: two for the upper differential mounting points and two for the lower differential mounting points. The polyurethane mounts have been specifically engineered to provide the optimal balance between stiffness and compliance, ensuring that the differential is securely mounted while still allowing for some movement to prevent undue stress on the drivetrain.

Installing the Whiteline Power Kit is a straightforward process and can be done by an experienced DIY mechanic or a professional garage. The kit comes with detailed instructions to guide the installation process. The use of polyurethane mounts may require some adjustments to the drivetrain alignment, and Whiteline provides recommendations on how to address this issue.

By upgrading the rear differential mounts with the Whiteline Power Kit, Impreza WRX and STI owners can expect improved handling, increased power transfer, and better overall drivability. This kit is an excellent investment for those who demand the best performance from their Subaru and regularly push their vehicle to the limit.
