Win-Tron Racing

Win-Tron Racing (formerly known as Country Joe Racing) is an American professional stock car racing team that currently competes part-time in both the NASCAR Gander RV & Outdoors Truck Series and the ARCA Menards Series. Specifically, they currently field the No. 32 Chevrolet Silverado for Howie DiSavino III in truck and the No. 32 Chevrolet for Gus Dean and DiSavino III in ARCA. In a partnership with Hill Motorsports, they also fielded Dean at the Truck Series race at Daytona in Hill's No. 56 truck.

After the team previously reduced its Truck Series operation to part-time in 2015 and 2016 due to lack of sponsorship, Win-Tron partially took over operation of Self's family-owned team starting at Bristol in August 2015. This came several months after fielding an ARCA car for Self at Daytona as a teammate to regular driver Shane Lee. This partnership ended when Self closed his own team and drove for Niece Motorsports in 2018. However, after a two-year absence, the team restarted their truck operations in 2020 with DiSavino III running part-time.

History
The team, then known as Country Joe Racing, was founded in 2007 by Kevin Cywinski and Nate Thiesse. Originally, the team ran in the American Speed Association, owned by Lakeville, Minnesota businessman Joe Miller, with Cywinski as their driver. Along the way, they would also enter the ARCA RE/MAX Series in 2004. Through a partnership with Chip Ganassi Racing, the team ran development driver Ryan Hemphill. Hemphill would take six wins in his rookie season but finished second to Frank Kimmel. After Hemphill graduated to the Busch Series, the team fielded Miller's son Joey Miller. The team ran a limited schedule in 2004, but scored a win in their first start at Nashville Superspeedway. Making the full-time move in 2005, Miller would rack up an impressive five wins as well as that years ARCA Rookie of the Year title. However, he was runner-up to Frank Kimmel for the championship.

After Miller moved up to the Truck Series for 2006, CJR hired another ASA driver, Blake Bjorklund. Although Bjorklund missed the races at Daytona and Nashville, he rallied with two poles and his first win at Salem Speedway. Bjorklund would move to the Truck Series for the 2007 season. After the 2007 season, Miller would sell the team's assets to Cywinski and Nate Thiesse.

In 2014, the team signed ten-time ARCA champion Frank Kimmel to drive the team's No. 44 in the ARCA Racing Series, and added a full-time Camping World Truck Series team with rookie driver Mason Mingus in the No. 35.
