Dinan Supplemental Ride Quality & Handling Kit for BMW E60 535i / 545i / 550i

The Dinan Supplemental Ride Quality & Handling Kit D193-6001 replaces the bump stops on the E60 BMW 535i, 545i and 550i 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, as the product photos show.

Fitment is the 2008-2010 535i, 2004-2005 545i and 2006-2010 550i sedan, matching Dinan's listing and other retailers. The E60 535xi is not supported. 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. Labor is minimal when it goes in at the same time as the Dinan springs. 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.
