Steve Millen was one of the key forces behind Nissan's IMSA success' during the late 1980's and early 1990s. Millen is a New Zealander and, prior to joining the nascent Nissan GTO program in 1989, Steve had established himself as an all-around driver in the mold of Jimmy Clark and A.J. Foyt, capable of winning in anything with four wheels, whether it was stadium trucks, rally cars, formula racers, midget cars or sports cars. However, Steve's best and lasting achievements came behind the wheel of the Clayton Cunningham-prepared GTO/GTS 300ZX. During his seven seasons with this factory-backed Nissan team, Steve captured a GTO/GTS record 23 pole positions and 20 wins on his way to two driver championships in 1992 and '94. Among those wins were overall victories at the Daytona 24 hour ('94) and Sebring 12 hour ('93-'95) endurance events. Steve also competed successfully at Le Mans, taking both Rookie of the Year honors and the race lap record in 1990 driving the Nissan R90CK prototype, and racing his famous number 75 300ZX to a class victory and 5th overall in the 1994 race. After retiring from motor sports in 1995 following a serious racing accident at Road Atlanta, Steve directed his competitive energies to building his successful after-market and tuning company, "Stillen Motorsports".
