SPL Parts 2021+ BMW G80 M3/ G82/G83 M4 / G87 M2 Adj Rear Upper Camber/Lateral & Upper Traction Links

If you're looking to get the most out of your 2021-2024 BMW M4, especially if you've lowered it or plan on hitting the track, getting the rear alignment dialed in is crucial. The factory suspension geometry can lead to excessive inside tire wear and inconsistent grip, particularly when you're pushing the car hard. These adjustable rear upper links from SPL Parts are designed to give you the control you need to fix that. They replace the stock wishbone and guide links, allowing for precise adjustments to your rear camber.

SPL Parts uses a combination of strong, lightweight materials to build these links. The traction links are made from gun-drilled 6061-T6 aluminum to keep rotating weight down, while the main camber arm is a curved 6061-T6 billet aluminum piece. This curved design helps clear other suspension components. Instead of soft rubber bushings that can flex and wear out, these links use smooth, Teflon-lined rod ends for direct feedback and consistent alignment. The adjustment mechanism is also well thought out, with a rotating clamp design for quick changes and a unique double adjuster on the camber arm that lets you make tweaks without removing the arm from the car. Even the adjustment screws are titanium, further reducing weight and adding a nice touch.

These links are proudly made in the USA. By allowing you to precisely set your rear camber, you can significantly reduce premature tire wear on the street and maximize the grip your M4 has in corners on the track. Getting the alignment right is key to both performance and longevity of your tires.
