BMW Suspension Parts

Enhance your BMW's performance with our premium control arm upgrade kit from Turner Motorsport! This kit provides a significant handling upgrade without sacrificing ride quality. Perfect for enthusiasts looking to replace their factory control arms with sturdier, high-performance alternatives, this kit features stiffer bushings and ball joints for improved precision.

Key Benefits:

Improved Handling: Experience more precise and responsive steering, giving your BMW a sportier feel. Increased Durability: Our control arms are much sturdier than factory units, ensuring long-lasting performance. Negative Camber Adjustment: Adds approximately 0.75 degrees of negative camber to the front, enhancing cornering grip and stability. Complete Kit: Includes all four M3-specific lower control arms with mounting hardware. M3 Headlight Leveling Rod: Necessary for proper installation, ensuring your headlights are correctly aligned. Important Note for Z4 Models: For Z4 owners, please be aware that the M3 headlight level sensor rod is positioned differently. A custom solution will be required to attach the sensor rod to the control arm. Currently, we do not offer a direct solution for this issue.

Upgrade your BMW's suspension with confidence! Enjoy a smoother, more controlled ride with our premium control arm upgrade kit!

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.

• Enhanced Camber Adjustment: Offers a wide range of adjustment for precise rear camber alignment, optimizing performance on the street or track.
• Durable Construction: Features gun-drilled 2024 Aluminum traction links and a 6061-T6 Billet Aluminum rear upper camber arm, black anodized to prevent corrosion.
• Improved Articulation: Replaces soft factory rubber bushings with smooth, Teflon-lined rod ends, eliminating bushing deflection.
• Lightweight Design: Reduces unsprung weight with aluminum components and Blue Anodized Titanium Socket Head Cap Screws.
• Easy Adjustment: Innovative 360-degree rotating clamp design and double adjuster feature allow for quick and precise camber adjustments without removing the arm.

Upgrade your BMW G8X M3 or M4 with these Rear Upper Arms for superior performance, durability, and ease of adjustment.
