BMW 428i Coilover Suspension Kit - Dinan - Supplemental Ride Quality & Handling Kit - '14-'16 is Dinan’s add-on designed to pair with Dinan performance springs on the 2014–2016 428i.

It replaces factory bump stops with tuned, progressive-rate pieces that extend compression travel and curb harsh bottoming. By managing travel and effective spring rate, it adds mechanical grip and consistent cornering without sacrificing daily comfort. OE-quality and engineered for the F32 428i with Dinan springs, the kit includes four bump stops. Standalone install is about 7.8 hrs (RWD) or 8.2 hrs (xDrive); labor impact is typically negligible when installed with the spring set.
