The SPL BMW G2X Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for the G2X BMWs (M340i, M440i, etc) while eliminating bushing deflection resulting in sharpened steering response and driving precision. The ability to run more negative camber and a slightly wider track width greatly improves the peak lateral grip available. This is especially important with better tires and a must-have for anyone looking to prevent excessive outer shoulder wear (and heating) on their tires due to a lack of camber. 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. Suitable for all uses, from daily driver to race car.
