Steve Millen Racing

STILLEN® founder Steve Millen has been racing across the globe as a professional driver for over 30 years. From Formula Fords in Singapore, Rally Cars in Africa, Trucks in football stadiums, to Nissan Prototypes at Le Mans and the 24 Hours of Daytona; these are just some of Steve's victory credits. Steve captured the prestigious IMSA GT Driver's Championship in both 1992 and 1994 driving his Cunningham Racing prepared Nissan 300ZX Twin Turbo racecar. His lengthy list of wins has made him "The All Time Winningest Driver in IMSA GT History" a title that may remain intact for decades to come.

STILLEN - Who We Are

Steve Millen’s racing experience has influenced every aspect of STILLEN’s business.

STILLEN builds and sell parts that are tested and proven to work following a regiment of testing and refinement;  Professional product evaluation in real-world driving situations gives STILLEN a distinct advantage. Car & Driver, Road & Track, Motor Trend, Automobile, AutoWeek, /Drive, DSport, The Smoking Tire, and Super Street have all reviewed and tested STILLEN products and project vehicles, and provided rave reviews
