Dinan Cars

Dinan Cars designs and manufactures aftermarket performance parts for BMW automobiles. The company was founded in 1979 by Steve Dinan and is headquartered in Morgan Hill, California.

Its parts are marketed through a network of authorized BMW dealers, independent auto repair shops as well as through their website. The company has a long-standing relationship with the BMW dealers, allowing Dinan-modified vehicles to retain factory warranty coverage and even qualify for BMW's Certified Pre-Owned program; something often lost when vehicles receive aftermarket modifications. There are 180 locations in the United States that sell Dinan parts or cars; 150 of them are BMW dealerships.

Dinan also designed and manufactured performance parts for the Mini Cooper line but the last model year designed for was in 2006. In addition Dinan has a history of building BMW racing engines for teams competing in the Grand-Am Rolex Sports Car Series Daytona Prototype class up until 2013.

As of 2013, Dinan is part of the Driven Performance Brand Group which includes B&M Racing and Performance, Flowmaster, and Hurst Driveline Conversions.

Founder Steve Dinan left the company in 2015 to join Chip Ganassi Racing. He was succeeded as president by Brian Applegate.
