Front Control Arm

The SPL BMW F2X/F3X Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for the rear wheel drive (RWD) F2X/F3X BMWs while eliminating bushing deflection resulting in sharpened steering response and driving precision.

Negative Camber Benefits

The ability to run more negative camber greatly improves the peak lateral grip available. Adding negative camber results in the tire having an optimal contact patch as the body rolls due to cornering forces. 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.

Wider Front Track Width Benefits

Further handling improvements can be had by increasing the front track width from the factory 60.5" (F3X) or 59.9" (F2X) to be closer to the M3's 62.2". If you applied the M3's width to the M340i it would reduce the outer front tire loading by roughly 20 lbs and apply it to the inner front tire. The result would be greater peak grip (~0.04G), improved stability, and faster lap times.

Roll Center Correction Benefits

Lowering the F2X/F3X results in a greater distance between the front roll center and the center of gravity. This acts like a longer lever, creating more body roll, bumpsteer, and requiring additional static camber angle to maintain the same handling. The SPL front lower control arms allow the roll center to be corrected for a wide range of ride heights to improve handling and stability.

The lower control arms come with a ride height sensor bracket to maintain the factory ride height sensor location, regardless of length of the arm to keep those finicky BMW chassis electronics happy.

SPL Parts is a performance suspension manufacturer that designs and tests their products all in-house here in the USA. Additionally, all materials used are sourced from American suppliers to ensure consistently high quality products. SPL Parts products are all constructed using chromoly seamless straight tubing, DOM mandrel bent tubing, and 6061 and 2024 aluminum for high strength and quality. All TIG welding and CNC machining is also done locally by professional welders and machine shops to meet exact quality standards and tolerance specifications. For anything from racing to street driven needs, SPL Parts offer an amazing line of premium quality products that are perfect to get your car back in spec.

These SPL front lower control arms open up a wide range of adjustment for roll center, camber, and track width adjustment and allow for full articulation with the correct ball joint angle. Instead of using traditional jam nuts, the main arm is slotted to allow the use of pinch bolts and SPL rotating clamps on their exclusive adjuster, making it easier to lock in track width and camber specifications.
