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.

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.

The front control arm bushings is the Achilles heel on the E39 models. The original factory bushings are fluid filled and rely on the fluid to absorb vibration and resist deflection. When the fluid is gone the rubber left over cannot match the original bushing's strength. The left over rubber is not stiff enough to resist the movements from the suspension. The result is a lot of vibration and reduced feedback and response from the steering. 

Meyle has addressed this issue with bushings that are not fluid-filled. The bushing is made of solid rubber that will last longer than the original bushing and is a bit stiffer than new originals for better response and feel. The lack of play from the solid rubber design will mean sharper steering, restoring much of the car's precision and 'connected' feel. 

This control arm comes with the Meyle HD bushings already pressed in. This makes for an easy swap out-swap in install. These arms replace the existing stock upper control arms - otherwise known as a tension strut or strut support arm. It's the arm with the twist. 

Meyle is a German brand in business since 1958 and all of their products are TUV approved and meet or exceed ISO standards. All Meyle HD parts come with a 4-year, unlimited mileage warranty.

Control arms, and their integrated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.

This control arm is an aftermarket OEM alternative part that comes with a 1-year warranty. They use the same designs as the original BMW parts on your car so they meet OEM standards for fitment and operation. We have compared these parts to the Genuine BMW and OEM brands and found few differences. This package is an unbeatable money-saving bundle to restore your E34's precise handling and steering. We also offer all of the OE or OEM brands if you are more comfortable with those levels of quality and performance or are planning to track or autocross your car (the cast components of the aftermarket kit will not be as good as the OEM parts on the track).

The aftermarket arm has the bushing pre-installed. The OEM and BMW arms include the bushing but it must be pressed into the arm by a qualified technician.

This item fits the following BMWs:
1989-1995 E34 BMW 525i 530i 535i 540i (Sedan and Touring)
