When an E9X is lowered beyond the limits of just lowering springs, the rear wheels toe-in excessively. This excessive rear toe leads to premature wear, that many people attribute to an increase in negative camber. It has become a common belief that an extremely low vehicle will wear the tires wrong as a matter of consequence. It has become standard practice to go as low as you can and proceed to replace your tires every five to ten thousand miles. Whats more is that when the vehicle reaches a certain ride height, the factory arms become maxed out and there is no way to compensate and dial in the proper toe. You're left with an improperly aligned vehicle that is in effect worse off than it was with the stock suspension installed.

This is not only uneconomical but improper and unsafe. ECS Tuning is proud to offer a solution for this problem in the form of Rogue Engineering E9X adjustable rear toe arms. These arms allow for greater toe adjustment on vehicles that have been lowered with a coilover suspension. With the toe set properly the tires can contact the road properly this maximizes grip and minimizes wear. 

Features:

• 100% machined and anodized, 6061-T6 lightweight aluminum arms
• High-strength, 3-piece, rod end (with carbon fiber reinforced, PTFE race) offers longer life for street compared to standard rod ends
• SEALS-IT Rod end seals keep dirt, water, and other contaminants out
• Rod ends feature grease fittings, to allow for rod end serviceability.
• Lighter than stock!  (Stock is 875g, RE arms are 640g)
• Extremely easy installation and adjustment (your alignment shop will LOVE you!)

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.

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
