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.

Add negative camber to the front wheels of your BMW to increase the stock handling limitations and reduce the issues with outer tire wear during hard cornering. The increased camber adjustment allows for more responsive turn-ins and can slightly reduce the tire wear on the outer edge of the tire.

Benefits:

• Replaces front upper control arms with ones that increase negative camber up to -0.5 degrees
• Improves grip of front tires
• Evens out tire wear during aggressive cornering

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)

For someone looking for superior performance and longevity these sealed monoball bushings are the best upper thrust bearing you can buy for an F22 2-series or F3X 3/4-series. The advantage of a monoball bearing is that it will not deflect under load. All of the rubber bushings move in all sorts of directions and that changes your alignment, especially when used with big brake kits or when driven hard. The condition worsens as the bushing wears out. The Dinan monoball sits in a CNC machined aluminum housing which has zero deflection. The monoball allows complete freedom of movement but only at the desired angles. What you get is superior steering precision, better handling from more consistent alignment, and almost infinite bushing life. And thanks to the inner liner and sealed rubber boots there's none of the extra noise or reduced service life of fully solid race bushings. 

We strongly advise using these with new control arms. BMW recommends that the bushings be replaced only once per set of control arms. So if your thrust arm bushings have been replaced already then we do not recommend re-using the arms. The other reason is that the aluminum arms stretch over time which will make the bushings loose inside the arm. Other manufacturers recommend filling the stretched arms with paste but replacing the control arm is the better solution.
