SPL Parts 06-13 BMW 3 Series/1 Series (E9X/E8X) Front Lower Control Arms

The main arm on these SPL Parts front lower control arms is slotted to accept pinch bolts, a detail that matters for making precise adjustments to your BMW E9X or E8X chassis. These arms are built to give you a wide range of adjustability for roll center, camber, and track width, allowing you to dial in your suspension for better handling. They are designed to work with the proper ball joint angle for full articulation, and they replace the stock arms that can flex and bind under hard use.

SPL Parts uses their exclusive Double Adjuster system, which is machined from 4130 Chromoly and drilled to save weight, then given an electroless nickel plating for corrosion resistance. This system uses rotating clamps to lock down your camber and track width settings, eliminating the need for jam nuts and making adjustments much simpler. The hardware is blue anodized titanium, which further reduces unsprung weight without sacrificing strength. For vehicles that have been lowered, stainless steel spacers are included to help correct the roll center. The use of FK Rod Ends and high-misalignment spherical bearings in place of the OEM rubber bushings means you get a more direct connection to the road and smoother suspension movement.

This pair of control arms is proudly made in the USA and includes the headlight adjusting rod for the street version. They fit a wide range of BMW 1 Series and 3 Series models from 2006 through 2013, including popular cars like the 128i, 328i, and 335i. If you're looking to fine-tune your BMW's suspension geometry, these adjustable control arms are a solid option.
