SPL Parts 2014+ BMW M2/M3/M4 (F8X) Rear Upper Control Arms

If you're looking to dial in your BMW M2's rear alignment, especially after lowering it, these adjustable Rear Upper Control Arms from SPL Parts are a solid choice. The factory suspension geometry can lead to excessive negative camber when the suspension compresses, which eats away at the inside edge of your tires and can hurt acceleration traction. These arms allow you to precisely adjust your rear camber, giving you the flexibility to optimize it for street driving or track days. They replace the stock links commonly known as the rear wishbone and rear guide links.

SPL Parts builds these arms from gun-drilled 2024 Aluminum, keeping unsprung weight down while maintaining strength. They're then Black Anodized to resist corrosion and give a durable finish. The adjustment mechanism is a neat 360-degree rotating clamp design made from 6061-T6 Aluminum, allowing for quick and accurate camber changes without the hassle of traditional jam nuts. These clamps are secured with Blue Anodized Titanium socket head cap screws, further reducing weight. Inside, you'll find FK Spherical Bearings with Teflon liners. These are made in Connecticut and are chosen for their smooth operation, low friction, and ability to eliminate the deflection you'd get from the soft factory rubber bushings, ensuring your alignment stays put under load.

This kit comes with everything you need for one car, including four total arms, and is proudly made in the USA. Having the ability to fine-tune your camber is key to getting the most out of your tires, whether you're commuting or hitting the track.
