SPL Parts BMW F8X M2/M3/M4 Front Lower Control Arms

Rubber should be saved for the tires. The factory front lower control arms on BMW F8X M cars including F80 M3, F82/F83 M4 and F87 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 F8X M cars including F80 M3, F82/F83 M4 and F87 M2 for serious driving, these pieces are a key part of getting the alignment and feedback you want.
