How do these inserts improve the car's handling?

These inserts replace the bushings in your rear subframe to reduce movement and misalignment. This results in a more direct and connected feel from the rear of the car, especially noticeable during cornering.

What is the material of the inserts made from?

The inserts are made from Whiteline's advanced synthetic elastomer formulation. This material is known for its resistance to common automotive fluids like oil and grease, as well as ozone and general weathering, ensuring durability.

Do I need to replace my original bushings with these inserts?

No, these inserts are designed to work in conjunction with your vehicle's original factory bushings. They enhance the performance of the existing bushings rather than replacing them entirely.

Product Details

Whiteline is known for making well-built suspension components that improve handling. This rear crossmember mount insert kit is designed for your 2008-2017 Subaru Impreza WRX or STi, and it works by replacing the bushings in your rear subframe. The goal here is to significantly cut down on how much the rear crossmember can misalign or move around, which can make the rear of your car feel much more connected and responsive when you're going around corners.

The inserts themselves are made from a tough synthetic elastomer that Whiteline has developed. This material is built to stand up to oil, grease, ozone, and general weathering, so it should last a long time. They're designed to work with your car's original factory bushings, not replace them entirely. Whiteline also includes internal grease reservoirs that help keep things self-lubricated for better friction management, and they supply a special grease with molybdenum disulfide for extended life. This kit is a solid option if you're looking for a more direct feel from your rear suspension, especially if you participate in motorsports.
