Dinan Suspension Link Kit – BMW M2 / M3 / M4 (2015-2020)

OVERVIEW

Dinan's high-performance Rear Suspension Link Kit adds precision and predictability at the limit. The stock rear toe link uses rubber bushings and a curved forged alloy rod that flexes under hard acceleration and braking, letting the rear wheels take on excessive toe change and making the car feel unstable. Dinan stops the flex by replacing the rubber bushings with Teflon-coated machined steel rod ends and the OEM curved bar with a straight billet aluminum rod — left- and right-hand thread lets rear toe be set quickly by turning the tube instead of fighting the factory eccentric adjusters.

The stock forward lower trailing links carry rubber bushings of their own that let the rear axle behave sloppily under load; Dinan replaces them with fixed-length billet aluminum rods on Teflon-coated rod ends. Rubber boots seal each rod end against dirt and road grime so the joints last.

SPECS

• Replaces the stock rear toe link and rubber bushings with a precision-machined black-anodized aluminum tube on racing-quality rod ends
• Replaces the stock forward lower trailing link and rubber bushings with a precision-machined black-anodized aluminum tube on racing-quality rod ends
• Rod ends are Teflon-lined for quiet operation
• Rod ends use left- and right-hand thread so rear toe is adjusted by turning the aluminum tube
• Rear toe links are adjustable; trailing links are fixed length and are preset by Dinan — never to be adjusted
• Rubber boots protect the rod ends from environmental damage
• Improves stability during hard cornering and response by eliminating rubber bushing deflection
• Shipping weight: 10 lbs
• Dinan published labor time: 4 hours
• Fastener torque: 74 ft-lbs
• Emissions: "This part is legal for sale or use on Emissions Controlled Vehicles, Uncontrolled (Non-Emissions Controlled) Vehicles, and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations."
• Dinan warranty: on a vehicle still covered by the BMW new-car warranty, the remainder of that warranty (typically 4 years/50,000 miles); otherwise 2 years, unlimited mileage. Wear items, maintenance services and fluids are excluded.

TECH RESOURCES

Additional Parts Required

• Four-wheel alignment. Dinan requires the rear alignment to be reset after installation — rear toe is then set with the Dinan toe links rather than the factory eccentrics. Budget for this before ordering.
• Torque wrench capable of 74 ft-lbs, and secure jack stands. Installer-supplied.
