Cusco Rear trailing arm WRX GC/GD

When you're looking to dial in the rear suspension on your 1993-2007 Subaru Impreza, especially if you're pushing it hard on the track or autocross course, the rear trailing arms play a crucial role. These Cusco trailing arms are built to give you more precise control over your rear wheel alignment, helping to keep your tires planted and predictable during aggressive driving. They replace the factory arms, offering a more solid connection between the chassis and the hub assembly.

Cusco is well-known for making solid suspension components, and these trailing arms are no exception. They're constructed from strong steel tubing, which is a step up from the stock stamped arms, providing increased rigidity. This means less flex under load, so when you make adjustments to your alignment, you get the benefit of those changes more directly. The arms are designed to fit right into the factory mounting points, which simplifies installation compared to custom fabrication. You'll notice improved responsiveness from the rear end, especially when cornering or under braking, as the suspension can do its job more effectively.

For installation, you'll typically want to have a good set of wrenches and sockets, and it's always a good idea to have a torque wrench handy to tighten everything to spec. Since these arms affect alignment, it's highly recommended to get a professional alignment done after installation to ensure everything is set up correctly for your driving style. This is a significant upgrade for anyone serious about improving their Impreza's handling characteristics.
