Front Control Arm

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!

BMW's are notorious for their failure-prone control arm bushings. The pliable rubber bushings, present even in M performance models, allow substantial movement of the front wheels to enhance everyday driving comfort. However, they also permit significant alignment changes, leading to a disconnected and numb road feel that detracts from a confidence-inspiring driving encounter. Over time, the fluid-filled rubber bushings succumb to fatigue and cracking due to continual deflection and ozone degradation, ultimately resulting in the leakage of damping fluid and complete failure.

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available! Our experience with spherical control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).

The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise. We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting. The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment. What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.

Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set, and are available (T599476) if you would prefer that option.

These bushings have the hole off-center to give your car a little more track, caster, and camber. This style came as standard equipment on E30 M3s (8/89-later) and 1995 E36 M3 but will work with any E30, E36, Z3.

Rubber control arm bushings are designed to flex and absorb energy. That's fine on a streetcar but on an all-out racing machine you want your alignment to stay constant. We have picked Delrin for this application due to its high rigidity and low coefficient of friction allowing for minimal suspension bushing deflection (geometry change) but decreasing bushing windup or drag (friction). They are not recommended for street-use but highly-recommended for track cars.

To save time, pick up a pair of new bushing carrier brackets and hardware. This will save you the time and hassle of pressing out the old bushings. This will especially save you time if you're buying new control arms at the same time (no time wasted removing the old brackets from the arms). Stainless steel set screws included.

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)

Looking for upgraded lower control arms that don't limit adjustment capabilities like the OE control arms? These Turner Performance Lower Control Arms may be exactly what you need! These CNC'd billet aluminum control arms allow you to adjust roll center, camber, and track width easily and lock in your adjustments securely.

The construction of these control arms allows for significant weight savings, reducing unsprung weight, while maintaining high levels of strength that is up to track use and abuse. Instead of using traditional jam nuts, these Turner Control Arms utilize a pinch bolt and rotating clamp design that allows high clamping forces to lock in track width and camper specifications without making it difficult to keep bearings properly aligned. Stainless steel spacers are included to enable roll center correction for lowered vehicles. To further improve control arm operation over the OE design, these control arms use FK rod ends and high misalignment solid spherical bushings to get rid of binding and flex.

Features:

Lightweight Aluminum, Titanium, Chromoly and Stainless Steel construction
Correct ball joint angle for full articulation
Clamp design allows for easy access to lock down your alignment settings
Low friction 3-piece Teflon lined FK spherical bushings and Heim joints/rod ends
Multiple size stainless steel roll center spacers for precise adjustment
