2003–2005 . After signing a
driver development contract with
Chip Ganassi Racing, Stremme started fifteenth in his Busch Series debut at
Nashville Superspeedway in April 2003, driving the No. 1 Dodge for
Phoenix Racing, and finished seventh in the race. He finished fourteenth in both of his next two starts, before coming to sixth at
Nazareth Speedway. He led 32 laps in that race, which were the first in his career. Stremme finished fourth after starting third at Nashville in June, and duplicated the result at the
Milwaukee Mile. He had a tenth at Kentucky and a ninth at Memphis. Stremme's worst finish that year was a 31st at Dover. Due to a contract obligation, Finch had
Jamie McMurray back in the car for the final two races, and Stremme moved to
Braun Racing for the remaining two races. Stremme led 48 laps at Rockingham, finishing fifth, and additionally drove the No. 30 Sport Clips Dodge home in 14th. His strong finishes in his part-time schedule was enough to secure him the 2003 Busch Series Rookie of the Year award, despite competing in only 18 of the 34 races. Stremme raced in the No. 32
TrimSpa Dodge Intrepid in
2004. Stremme started fourth and finished sixth in the season opener at
Daytona International Speedway. Despite winning his first career pole at Milwaukee, and finishing that up with a second, Stremme's team began to run mid-pack with a handful of top-tens mixed in. Braun Racing then made the announcement that they were going to replace Stremme with
Shane Hmiel, who was just coming off a suspension. Ganassi then made a deal with
FitzBradshaw Racing to secure Stremme a ride. For the remainder of the 2004 season, Stremme was to replace
Casey Atwood in FitzBradshaw's
U.S. Navy-sponsored No. 14 Chevrolet. For the next season, FitzBradshaw's team would begin running Dodges and Stremme would be retained to drive the No. 14 full-time. In
2005, Stremme posted five top-five finishes and finishing thirteenth in points, when it was announced he would run full-time in the Nextel Cup Series.
2004–2007 In June 2005, Stremme made his Cup debut in
2005 driving Ganassi's R&D No. 39 Navy
Dodge at
Chicagoland Speedway. He started 31st and would finish sixteenth in his debut. He also had finishes of 42nd at Richmond and Miami, and a 36th at Charlotte. Ganassi announced Stremme would go to the Cup series, driving the No. 40
Coors Light Dodge in
2006. In 2006, Stremme had a best finish of eleventh at
New Hampshire International Speedway and
Homestead-Miami Speedway. He finished 33rd in points after missing both road course races that season. In addition, he made his
Craftsman Truck Series debut at
Martinsville Speedway, finishing 32nd in the No. 04 Dodge for
Bobby Hamilton Racing. In addition, he won his first career
ARCA RE/MAX Series race at
Michigan International Speedway, driving the No. 61
Hantz Group Dodge for
Rusty Wallace. Despite solid equipment with Ganassi, Stremme failed to notch a single top-ten in 34 races. Stremme followed up his disastrous rookie season with another poor season in 2007. He started 2007 starting sixth in the 49th annual
Daytona 500 and went on to finish eleventh. Three weeks later he would get his best career start, second in the
UAW-DaimlerChrysler 400 at
Las Vegas Motor Speedway. In the
Samsung 500 at
Texas Motor Speedway he would get his first career top-ten finish. Two weeks later, he would follow that up with a career best finish, eighth in the
Aaron's 499 at
Talladega Superspeedway. During that season, Stremme shared driving duties of the No. 41
Wrigley Dodge Charger in the Busch Series with Ganassi teammate
Reed Sorenson. It ran numerous paint schemes including
Wrigley's Spearmint,
Doublemint,
Juicy Fruit, and
Winterfresh. He was able to get his second career Busch pole at Nashville but ended up eleventh in the race. In addition, he drove a part-time schedule in the No. 22
Supercuts Dodge for
Fitz Motorsports.
2008–2012 race in 2008 He was replaced in the No. 40 Dodge by
Dario Franchitti in 2008 after the 2007
Indy 500 Champion was signed to drive in Sprint Cup. Stremme returned to the Nationwide Series driving for
Rusty Wallace Racing, in the No. 64 Atreus Homes & Communities Chevrolet. He was originally scheduled to run a handful of races, with
Chase Austin and
Max Papis driving the rest of the year, but after starting the season in the top-fifteen in points, the schedule was modified to allow him to run every race except the road course events. He had five top-fives and sixteen top-tens, on his way to an eleventh-place points finish. In the latter portion of the year, Atreus left the team, and
AVIS, Loan Star Title Loans, and the
Penske Corporation became the team's new primary sponsors. He drove the No. 15 Hyprene Ergon
Toyota Tundra in two Truck races that season as well, in addition to returning to the No. 40 Sprint Cup team, filling for the injured Franchitti at Talladega. In 2009, Stremme signed to drive the No. 12 car for Penske Racing full-time in the Sprint Cup Series, replacing Ryan Newman who moved to the No. 39 car for
Stewart Haas Racing. The team lost its sponsor when
Verizon Wireless bought Alltel, thus negating the grandfather clause. The car was blanked similar to the Penske used in the IRL, censoring their
Phillip Morris USA sponsorship with "Team Penske". Stremme nearly won the
2009 AMP Energy 500 running near the front for the lead, but a green-white checkered ruined his day, causing him to run out of gas. Throughout Stremme's season for Penske, he did not score a single top 10. Stremme was released from the contract with Penske on November 3, because their new driver for 2010,
Brad Keselowski, was finished with his prior contract agreements with
Hendrick Motorsports. He missed the Texas and Phoenix races and failed to qualify for the Homestead race driving for James Finch in the No. 09 car. Stremme attempted sixteen races with
Latitude 43 Motorsports in 2010, failing to make five. Stremme attempted a select number of races with newly formed Inception Motorsports in the No. 30 Chevrolet in 2011, along with a limited Nationwide Series schedule with
ML Motorsports. He ran in the Sprint Cup Series for 2012 with Inception Motorsports, switching to Toyotas.
2013 For 2013, Stremme returned to the No. 30, now
Swan Racing Company, with the exception of the
Daytona 500 where
Michael Waltrip drove the car, renumbered for the event with No. 26. Unlike Inception Motorsports, where Stremme was a start and park driver, Swan Racing has full sponsorship. In the
Camping World Truck Series inaugural
running of the
Mudsummer Classic at
Eldora Speedway, Stremme served as the spotter for
Ken Schrader. After only recording four top-twenty finishes in the first 26 races in 2013, Stremme was released by Swan Racing following the September race at Richmond International Raceway, being replaced by
Cole Whitt.
2014 Stremme was signed by
Circle Sport to run the No. 33 beginning at the
STP 500 at Martinsville. He attempted twelve races before being released, and has not raced in NASCAR since then. ==Post-NASCAR career==
