Rear Control Arm

Stock rear lower control arms offer very little adjustment for alignment, especially in lowered vehicles, due to their use of an eccentric bolt. These aftermarket performance control arms from ECS Tuning are designed for maximum adjustability, allowing you to maximize handling and minimize tire wear.

To ensure maximum reliability, ECS Tuning's control arms are constructed from strong, lightweight 6061-T6 aluminum and feature a 303 stainless steel center turnbuckle that offers over 8 degrees of fast and precise camber adjustment. The inner bushing is a stock style serviceable OEM bushing for long life and inexpensive maintenance.

Features:

Durable construction suitable for the daily driver and track car alike
8+ degrees adjustment range for dialing in any suspension and wheel/tire setup
Center located adjuster for maximum clearance during adjustment
OEM-style bushing for long life and inexpensive service
Black anodized 6061-T6 aluminum with 303 stainless steel turnbuckle
Includes new hardware
*With the exception of the stance community, most enthusiasts will need no more than a few degrees of adjustment range. Total adjustment often is dependent on wheel/tire clearances.

The rear lower control arms on E82/E9X models are the weakest link in the rear suspension. The arm is made from folded sheetmetal and it bends and deforms easily. Not only will it deform from potholes and curbs, tow truck drivers love to hook onto them without realizing how weak they are. We have seen other race teams complete the box section to make them stronger. A bent arm will throw off the geometry in the suspension, potentially affecting handling and tire wear. These aluminum arms are both lighter and stronger than the factory sheetmetal arms and is the best solution for chronic bending of the stock arm. These are a direct replacement to your stock arms with no changes needed to your alignment. New high-grade hardware is included.

Note: the stock arm is designed from the factory to be intentionally weak. These arms will bend so that something else in the suspension does not break. Our race cars used the stock sheetmetal arm but we replaced them often. We found that it was better to finish a race with a bent arm than not finish due to a catastrophic failure. The ECS arms are still designed to be the weakest link but are far stronger than the factory arm and will not bend as easily.

These rear camber arms allow for significantly greater camber adjustment over stock, a major benefit to lowered cars that need their camber readjusted to prevent tire wear and poor handling. These camber arms also provide increased stability and predictability versus the stock camber arms with rubber bushings.

Technical Specifications:

• Lightweight Aluminum, Titanium, and Chromoly construction
• Anodized Black for corrosion protection and durable finish
• Gundrilled center hex links for maximum weight savings
• Teflon lined FK Rod Ends
• Made in the USA

ALTA Rear Control Arms are the ultimate upgrade for your MINI, replacing your rear lateral links with a solid and performance-focused design. These control arms enhance traction and handling while giving you precise control over camber and toe settings. The flexibility of ALTA control arms allows for fine-tuning without the hassle of removing and reinstalling the linkage. Simply adjust the lock nuts and twist the center section to achieve your desired settings.

These control arms are the perfect complement to other suspension products like springs, coilovers, or sway bars.

Key Features of ALTA Rear Control Arms:

• CNC machined from 6061 aluminum rod for durability.
• Heavy texture powder coating for corrosion resistance and added style.
• Teflon-lined spherical rod ends for a solid connection and improved articulation.
• Aircraft-quality spherical bearings for smooth and precise movement.
• Injected Nylon around the ball center for quiet operation as the part ages.

For a comprehensive rear end upgrade, consider purchasing two sets of control arms to replace both upper and lower control arms. This minimizes deflection from the OEM rubber bushings and reduces weight. Please note that on models with Xenon-style headlamps, some modifications to the leveling sensor mounting may be necessary. For additional details, consult your ALTA dealer or our Tech Department.

ALTA Rear Control Arms come with high-quality hardware, including corrosion-resistant spacers and Grade 8 adjustment nuts.

Dinan's high-performance Rear Suspension Link Kit adds precision and predictability at the limit.

The stock rear toe link setup is built with rubber bushings and a curved forged alloy rod which can easily flex. During hard acceleration and braking, this flex allows the rear wheels to have excessive toe change which ultimately causes the car to be unstable. Dinan stops the flex by replacing the rubber bushings with Teflon-lined machined steel rod ends that significantly reduce pliability while also swapping out the OEM curved bar with a stouter billet aluminum arm, thus adding stability. Like the rear toe links, the stock front trailing links also incorporate rubber bushings. Flex in these bushings allows the rear wheels to behave sloppily under heavy loads. Dinan adds precision by replacing these links with billet aluminum arms and precision ball joints just like the ones found in the Dinan front monoball kit.

Have confidence in your F90 M5 when pushing the envelope without worry of erratic suspension play or sacrificing ride quality and comfort. Whether it be at the drag strip doing quarter mile runs or simply getting the jump off the line at a stop light the end result with Dinan's Rear Suspension Link Kit is a more stable and planted driving experience when pushing the car to its limits.

Benefits of the Dinan Rear Suspension Link Kit for the BMW F90 M5:

Replaces the stock rear toe link & rubber bushings with a precision machined black-anodized aluminum arm and racing-quality rod ends.
Rod-ends are Teflon-lined for quiet operation.
Rubber boots protect rod ends from environmental damage for long-lasting performance and removes the need for constant cleaning.
Replaces the stock forward lower trailing link & rubber bushings with a precision machined black-anodized aluminum arm and precision ball joints.
Bearings are nylon-lined for quiet operation.
Dramatically improves vehicle stability during hard cornering.
Improves response by eliminating the deflection of the rubber bushings.
