Days of Thunder Hamilton broke into the Winston Cup ranks in a very unusual way. He was asked to drive one of the "movie cars" for the
1990 film
Days of Thunder, qualifying fifth in the movie car at the
1989 Autoworks 500 in Phoenix, in a car that was not intended to be competitive. The car was a No. 51
Exxon-sponsored
Chevrolet, portrayed in the movie as being driven by Rowdy Burns.
1988–1994 Hamilton made his NASCAR debut in the
Busch Series in 1988 at
Charlotte Motor Speedway driving the No. 16
Filmar Racing Chevrolet, finishing fourteenth. He competed in the next race at
Rockingham and finished twentieth. He drove full-time in the
Busch Series in 1989 driving the No. 8 Lighting & Fans
Buick for
FILMAR Racing, finishing eleventh in points, and winning his only career Busch race at
Richmond International Raceway. He made his Winston Cup debut in a "Days of Thunder" car owned by
Hendrick Motorsports. He led five laps but finished 32nd after an engine failure. He matched his 11th-place points finish in 1990 with
Filmar Racing, when he was picked up by
Tri-Star Motorsports to run Winston Cup full-time beginning in 1991, driving the No. 68
Country Time Lemonade Oldsmobile, posting four top-ten finishes and narrowly defeating
Ted Musgrave for Rookie of the Year. In 1992, Hamilton had two top-tens and finished 25th in points. He began 1993 with Tri-Star but was released early in the season. He spent the rest of the season in the Cup and Busch Series, posting two top-tens for
Akins-Sutton Motorsports. Hamilton also made five Busch Series starts in the No. 05 Key Motorsports Chevrolet. In 1994, he joined
SABCO Racing to driving the No. 40 Kendall Motor Oil
Pontiac Grand Prix. He had just one top-ten finish and left at the end of the season.
1995–2002 For the 1995 season, Hamilton moved to
Petty Enterprises to drive the No. 43
STP Pontiac. He posted ten top-tens and moved up to fourteenth in the final standings. The next season, he finished a career-best ninth in the points standings and won his first race at Phoenix, the first for Petty Enterprises since 1983. He also formed his own Craftsman Truck Series team and began competing in the series part-time. He won at Rockingham in 1997, but departed the team after falling to sixteenth in points. Hamilton then signed with
Morgan-McClure Motorsports in 1998 and in their eighth race together, he won from the pole, leading 378 of 500 laps at
Martinsville Speedway. He ended the season, finishing tenth in the points. He had another ten top-ten finishes in 2000 and finished that season off thirtieth in points. He left for
Andy Petree Racing to drive the No. 55
Square D Chevy. He won his final Cup career race at Talladega and finished eighteenth in points. He posted three top-tens in 2002 but suffered a broken shoulder late in the season, causing him to miss several races. Although his Cup Series run in 2000 was not successful, Hamilton made history regardless as he joined
Ken Schrader,
Terry Labonte, and
Mark Martin as one of the drivers to, at that point, win a race in each of NASCAR's top-three series when he won a
Craftsman Truck Series race at Martinsville.
Craftsman Truck Series Due to the injury, as well as an unstable financial situation at Petree Racing, Hamilton left the Winston Cup Series for the Truck Series driving for his own team, taking the Square D sponsorship with him. Driving the No. 4
Dana Dodge Ram Hamilton picked up two wins in his first year on the circuit and finished sixth in points. The following season, he picked up four wins and clinched the championship, marking the first time since
Alan Kulwicki's championship in 1992 that an owner-driver won a NASCAR championship. He switched to the No. 04 in 2005. In 2005, Hamilton started his Truck series season with a bizarre finish. He led the final laps of the 2005 Dodge Dealers 250 at Daytona International Speedway when
Jimmy Spencer got by with a few laps left and the white flag flew just before a crash occurred in turn 1. During the accident, Hamilton passed Spencer for the lead. Due to the scoring-loop rules, before the accident it was initially believed that Spencer won. Spencer drove to victory circle, but not long afterward it was determined that Hamilton won; Hamilton was at the final scoring loop as he was in the lead. Hamilton later won at Mansfield and went on his way to another sixth place points finish. Hamilton drove the No. 18 Fastenal Dodge for the first three races in 2006, but was diagnosed with cancer and never raced again, with
his son finishing out the season. ==Illness and death==
