BMW Control Arm Replacements & Upgrades

BMW F8X M3 M4 Rear Suspension Link Kit is designed to enhance the handling and stability of your high-performance BMW. This kit eliminates the vagueness and flex commonly associated with stock rear suspension links, which rely on rubber bushings that can flex under load. By replacing these with Teflon-coated, machined steel rod ends and billet aluminum rods, this kit ensures a more planted and secure feel, especially during hard acceleration, braking, and cornering. The rods feature a hex design for easy adjustments, making it an ideal upgrade for those running larger wheels and tires.

• Improved Stability: Eliminates flex under acceleration, braking, and cornering for a more secure feel.
• High-Quality Materials: Teflon-coated, machined steel rod ends and billet aluminum rods.
• Adjustable Design: Hex machined center rods for easy adjustment.
• Enhanced Handling: Reduces vagueness and provides a more planted driving experience.
• Ideal for Upgrades: Recommended for use with larger wheels and tires.
• Turner Motorsport Quality: Trusted performance parts backed by over 35 years of BMW tuning expertise.

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.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers.

Dinan's Rear Toe Links add precision and predictability at the limit.

The stock rear toe links are built with rubber bushings and a curved forged alloy rod. This design allows the rear wheels to have excessive toe change under hard acceleration and braking. All of this flex in the stock toe links causes the car to be unstable. Dinan stops the flex by replacing the rubber bushings with Teflon coated machined steel rod ends and the OEM curved bar with straight billet aluminum rods, thus adding stability. The Dinan rear toe link also incorporates a hex nut shaped center to aid in the necessary fine adjustment of the toe link that is tough to achieve using the stock link.

Features:

Replaces the stock rear toe link & rubber bushings with precision machine black-anodized aluminum rods and racing-quality rod ends

Dramatically improves vehicle stability during hard cornering

Improves response by eliminating the deflection of the rubber bushings

Rod-ends are Teflon-lined for quiet operation

Rod-ends incorporate left and right hand thread, which allows quick and accurate toe adjustment by simply turning center turnbuckle eliminating the need to struggle with the factory eccentric adjustment

Rubber boots protect rod ends from environmental damage for long lasting performance and removes the need for constant cleaning
