SPC Performance GM Rear Shim Set (18)

With two toe shims each of +/- 0.10, 0.20, 0.30, 0.40, and 0.50 degrees, plus two camber shims each of +0.25, +0.50, -0.25, and -0.50 degrees, this 18-piece set from SPC Performance gives you the fine-tuning capability you need for your rear alignment. These full-contact shims are designed to work on a range of GM vehicles, including popular models like the Chevrolet Sonic and Buick Encore, allowing you to precisely adjust toe and camber angles to correct alignment issues or dial in your suspension setup.

You can stack up to two shims at a time to achieve the maximum adjustment range for both toe and camber. This flexibility is key when dealing with factory tolerances or after modifications that can affect your alignment. The well-built nature of these shims ensures they sit securely and make full contact, providing consistent and reliable alignment corrections for your vehicle.
