Bridgestone Americas Inc. will be the official tire of the Sports Car Club of America (SCCA) and the sole tire supplier of the SCCA Club Spec program.

In a three-year partnership, the company aims to reinforce its "commitment to grassroots motorsports, enhancing its involvement in autocross, track days and time trials," say Bridgestone officials. 

Bridgestone’s Potenza RE-71RZ tire will support established classes, including Solo Spec Coupe, Club Spec MX-5 and Club Spec Mustang. The Potenza RE-71RZ will also serve as the official spec tire for the Club Spec Cayman class launching in 2027. 

“Bridgestone and the SCCA share a core commitment to making motorsports accessible, educational and fun,” says David Colletti, president of consumer original equipment tires, North America, Bridgestone Americas Tire Operations. “Partnering as the official tire of the SCCA and SCCA Club Spec furthers our investment in the heart of the racing community while enabling us to deliver peak Potenza performance every single weekend.” 

The Bridgestone Potenza RE-71RZ, an extreme 200TW summer performance tire, is specifically engineered for grassroots racing. The tire, along with its predecessor, the Potenza RE-71RS tire, is designed with features that improve fast lap times and enhance control.

Bridgestone’s notable results with its Potenza tires throughout the 2026 season include: 

• Captured 75% of class wins (350+), 70% of class podiums and top index honors at 21 of 24 national events across the 2026 SCCA Solo season 

• Accounted for 70% of eligible entries (3,300+ competitors) throughout the full season 

• Earned 55% of total event entries (732 entries) and 80% of the field in eligible street tire classes (729 of 908 drivers) at the SCCA Solo National Championships, which is the largest grassroots motorsports event in the world  

• Won 36 of 41 classes (88%), earned 103 trophies (85%) and set the event’s top overall index time by 0.7 seconds at Solo Nationals  

• Extended dominance into SCCA time trials, capturing 97% of podium finishes (38 class wins) and setting 19 class lap records during the 2026 National Tour season

“SCCA is honored to partner with Bridgestone and welcome the brand back into our community,” says Heyward Wagner, vice president of rally, solo and experiential programs. “Bridgestone was a tremendous supporter of SCCA Solo competitors 20 years ago, and many of our members still remember the impact the brand made. That history has paved the way for genuine excitement across SCCA to reunite with Bridgestone, celebrate that shared history and build on it through programs that support accessible, competitive and fun motorsports experiences for drivers at every level.”  

Bridgestone and the SCCA will continue collaborating on joint educational programs, trackside support and exclusive member experiences.

"The partnership will actively support key SCCA initiatives, including Track Night in America, which makes track time accessible to drivers of all skill levels, and SCCA Women on Track, which empowers broader female participation across all facets of grassroots motorsports," according to Bridgestone officials.
