SPL Parts BMW G8X Front Lower Control Arms M3/M4 X-Drive

Rubber should be saved for the tires. The factory front lower control arms on BMW G8X M cars including G80/G81 M3 and G82/G83/G87 M4 and M2 use soft rubber bushings that flex under load, which lets alignment and toe change right when you are asking the car to work the hardest. SPL Parts replaces those links with fully adjustable, spherical bearing components that keep the suspension honest and repeatable on both street and track.

Motorsport grade construction

Gun drilled 2024 aluminum links, SPL’s 6061-T6 rotating clamps and Teflon lined FK spherical bearings keep weight down while delivering precise, low friction movement. Stainless or titanium hardware is used throughout for strength and corrosion resistance, and every kit is designed, machined and assembled in the USA.

Front geometry where you want it

SPL front lower control arms give you independent control of camber, roll center and track width, which is critical when you lower the car or move to larger tire packages. That flexibility makes it much easier to get the steering feel and front grip you want without compromise.

We use SPL hardware across many of our own builds because it is easy to work with, holds settings and stands up to real track mileage. If you are dialing in BMW G8X M cars including G80/G81 M3 and G82/G83/G87 M4 and M2 for serious driving, these pieces are a key part of getting the alignment and feedback you want.
