Noffsinger was born into a motorsport-minded family in California. His father, Ace Noffsinger, was a business owner and engineer, and his mother was Patty. Both of his younger brothers, Bart and Todd, competed in CRA Sprint Cars and USAC Midgets, reflecting a household environment in which racing was a shared pursuit. Noffsinger graduated from Cypress High School in Cypress, California.
Noffsinger first attempted to qualify for a Cup Series race in 1987, seeking entry to the Winston Western 500, but failed to make the field. His Cup career extended across several seasons in the late 1980s and early 1990s, during which he completed a total of 3,555 laps — equivalent to 5,515.9 miles — while recording only a single lap led across his entire Cup tenure.
The 1988 season proved particularly difficult: Noffsinger failed to qualify on eight separate occasions during that year's Winston Cup Series calendar. His time in the series was marked by seven DNFs (did-not-finish results), which curtailed his ability to build a consistent record despite his commitment to the programme.
Road courses represented Noffsinger's strongest discipline, where he typically averaged finishes around fifteenth place. On intermediate ovals, however, results were considerably harder to come by, with thirtieth-place finishes representing a common outcome.
During the 1994 Cup Series season, Noffsinger attempted to qualify for three events — the Mello Yello 500, the AC-Delco 500, and the Slick 50 500 — without success.
He also competed in the NASCAR Busch Series during this period as part of a broader effort to maintain competitive activity across the stock car ladder.
Following the conclusion of his driving career, Noffsinger transitioned to the technical side of racing, working as a crew chief at the Winston Cup Series level. He spent time with Team Sabco during the mid-to-late 1990s, one of the more prominent organisations in the series at that time.
After leaving NASCAR competition entirely, Noffsinger joined the Richard Petty Driving Experience, based at the Walt Disney World Speedway. In that role he taught members of the public and NASCAR fans how to operate the manual-transmission stock cars used in the experience programme, providing instruction on the four-speed gearbox and the fundamentals of high-speed oval driving.
From 1999 to 2004, Noffsinger operated as an owner and occasional driver in USAC Silver Crown competition, using the programme as a vehicle for mentoring younger drivers. The team eventually disbanded due to financial difficulties.
In 2013, Noffsinger took on a non-racing automotive role when he served as the stunt driver in the viral Pepsi MAX and Jeff Gordon advertising video titled Test Drive, in which Gordon drove an unsuspecting test-driver in a high-performance car as a hidden-camera prank.
Noffsinger's career traces an arc common to many journeyman competitors of his era — capable road course performances constrained by limited resources, followed by a pivot toward the technical and instructional side of the sport. His work with Team Sabco placed him at the operational heart of a competitive Cup outfit, while his later role at the Richard Petty Driving Experience kept him embedded in NASCAR's broader culture as an ambassador to fans encountering stock car racing first-hand.
