Dinan D280-0015 is a high-performance rear suspension link kit for 2015-2026 BMW M2, M3, and M4 models using the F80/F82/F83/F87/G80/G82/G83/G87 chassis. The kit replaces the factory rear toe-link rubber bushings and curved forged alloy rod with Teflon-coated machined steel rod ends and a straight billet aluminum rod. Left- and right-hand threads allow precise toe adjustment while reducing flex under acceleration and braking, improving rear-end stability and predictability.
