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.

BMW G8X M3 M4 Rear Upper Arms are essential for maintaining optimal rear camber and minimizing tire wear for both street and track driving. The stock BMW setup can lead to excessive negative camber, especially noticeable in lowered vehicles, resulting in premature tire wear and reduced traction. These adjustable Rear Upper Arms provide a broad range of adjustment for precise rear camber alignment, crucial for both performance and longevity.
Upgrade your BMW G8X M3 or M4 with these Rear Upper Arms for superior performance, durability, and ease of adjustment.

After much anticipation, we are pleased to release our lowering spring kit for the BMW M3 G80 platform! Taking our experience from our highly popular F80 springs, the goal with this offering was to lower the M3 by a tasteful amount while keeping ride quality the same or better than stock. After multiple prototypes and valuable user feedback, we believe that we met our goal.
Our lowering springs are specifically designed to utilize the factory dampers. They are fully compatible with both standard as well as adaptive suspension. Each spring is made in the USA to our unique specifications for rates and geometries. The springs are made of high tensile chrome silicon and each unit is shot peened, pre-set, and 100% tested to ensure all the critical dimensions and rate/loads are within tolerance. The springs are then powder-coated with a stealth black finish for an OEM appearance.
Front Lowering: 1.4"
Rear Lowering: 0.7"
Stock Front Rate: 186 lb./in.
EMD Auto Front Rate: 194 lb./in.
Stock Rear Rate: 608 lb./in.
