Dinan Supplemental Ride Quality & Handling Kit for BMW 328i / 330i xDrive 2013-2018

The Dinan Supplemental Ride Quality & Handling Kit D193-3021 replaces the bump stops on the F30 BMW 328i xDrive and 330i xDrive when they are lowered on Dinan performance springs. Dinan tunes these progressive-rate bump stops to work with its springs.

On a lowered car the factory bump stops engage too early. The Dinan stops let the spring use its full compression travel, so the car is less likely to bottom out harshly, rides better and holds more grip in corners than with springs alone. They are made from OE-quality material for a progressive feel, as the product photos show.

Fitment per Dinan's chart is the 2013-2016 328i xDrive and 2017-2018 330i xDrive. It fits xDrive cars only; the rear-wheel-drive 320i, 328i and 330i use Dinan kit D193-3001. Dinan says its spring sets should be installed with the matching handling kit to reach the advertised ride height and ride quality.

The kit contains four bump stops. Installed on its own, Dinan quotes 8.2 hours of labor; installed together with the Dinan springs, the extra labor is negligible. Coverage is Dinan's limited warranty: the remainder of the vehicle's factory limited warranty (up to 4 years / 50,000 miles) or 2 years with unlimited miles, whichever is greater. Dinan will not warranty ride or handling complaints on spring-only installs that skip this kit. It ships in one small carton of about 8 x 6 x 4 inches at roughly 1 pound.
