BMW G8X Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for the G8X BMW M3/M4, and allow for full articulation with the proper ball joint angle. The main arm is slotted to allow the use of pinch bolts, and our rotating clamps on SPL Parts' exclusive Double Adjuster lock down camber and track width settings. No more jam nuts!! Long gone are the days of fumbling with multiple wrenches to tighten jam nuts in place while trying to keep your bearings oriented correctly. The lower control arms come with a ride height sensor bracket to maintain factory ride height sensor location, regardless of length of the arm to keep those finicky BMW chassis electronics happy. Our Double Adjuster is machined from 4130 Chromoly
