New GMG Racing Headquarters at The Thermal Club Takes the Spotlight in Gala Grand Opening

A dream of a lifetime that became a top priority in this decade is now a spectacular reality in the heart of the greatest high-performance automotive and road racing facility in the country.

GMG Racing Principal and Founder James Sofronas and his family and team unveiled their all-new and long-awaited headquarters facility located within the Thermal Club in a Grand Opening celebration last weekend that attracted a who’s who of VIPs and a guest list of both longtime and new customers of the top street performance shop and championship-winning racing team.

“It truly has been a lifetime goal of mine with GMG Racing to introduce a new and state-of-the-art multi-purpose headquarters facility to service our customers and top street car and competition clients,” Sofronas said. “The question of ‘where’ was answered when the amazing Thermal Club facility was introduced 10 years ago, and the right time for ‘when’ was at the beginning of this decade five years ago. Now, to finally cut the ribbon and unveil this true labor of love and unbridled high-performance automotive passion is an honor and privilege. GMG Racing’s future is at the Thermal Club!”

Sofronas, his family, key members of the GMG Racing team and the company’s entire staff and managers welcomed at the Grand Opening more than 250 guests who were the first to see the new Thermal Club GMG Racing headquarters. Notable attendees included Porsche Motorsport North America (PMNA) President Volker Holzmeyer, Mobil 1 Global Motorsports and Sponsorships Manager Jei Gort, Thermal Club Owner Tim Rogers, SRO America President Greg Gill, Senior Manager of Motorsports for Lamborghini North America Erik Skirmants, President of Troy Lee Designs Troy Lee and an enthusiastic group of GMG friends, clients and Thermal Club members.

Longtime GMG Racing team driver Kyle Washington, a close friend of all on the team, joined Sofronas for the actual facility ribbon cutting. Sofronas and Washington later reunited for the evening’s promised special car unveil, which was the first North American delivery of the new Porsche GT3 R Rennsport edition. The ultimate 992 Porsche track car, the GT3 R Rennsport unveiled at GMG – finished in Bare Carbon livery – is one of just 77 units that will be built in the production run, all featuring incomparable performance and a heritage-inspired retro spoiler best known in the U.S. as a “whale tail.”

The Thermal Club is a premier an unparalleled motorsports facility in the Greater Palm Springs region of California and known around the world. From there, GMG will continue the fine service it has provided to valued clients and customers for decades, but now with improved operations and customer support with a state-of-the-art facility with nothing but new installations and the latest technology and equipment. GMG will continue to accept all cars at the new location and provide its renowned products to clients, dealers and shops worldwide. And if a customer cannot get their car to the new facility personally, GMG’s safe and secure transport service is always available for a true door-to-door experience.

The relocation from GMG’s shop for more than the last two decades in Orange County marks a major milestone as the company approaches its 25th year of business as a leading high-performance shop for both street and competition cars in Southern California and beyond. The company’s current lineup of products and services will continue to be made available along with the introduction of innovative and new products for both existing and future vehicle platforms. With the new shop just 20 seconds away from Thermal pit lane, GMG Racing will be able to conduct rigorous testing and prototype development with unprecedented efficiency, ensuring that every product meets the high standards customers have come to expect.

With the Grand Opening complete, the current timeline for GMG Racing is to be fully 100% operational at the Thermal Club in the next 30 days after the final transition out of its Santa Ana facility in Orange County. An immediate program is the support of GMG Racing’s non-stop schedule of Thermal Club Winter Series races as well as exclusive track days and continuous off-season testing for the 2025 racing year ahead.

Noteworthy: While the next order of business for GMG Racing is the move to the new Thermal Club headquarters facility, this weekend GMG Racing closes out it’s national racing schedule with the season-ending Porsche Carrera Cup North America doubleheader at Circuit of The Americas (COTA) in support of the Formula 1 United States Grand Prix. Rounds 15 and 16 of the all-Porsche championship will run on Saturday and Sunday on the 3.4-mile, 20-turn Austin, Texas circuit.

Longtime GMG Racing team driver Kyle Washington looks for his first Masters Class race win of the season after third-place finishes this year at Sebring International Raceway and in the support races for the Formula 1 Canadian Grand Prix in Montreal in the No. 32 GMG Racing Porsche 911 GT3 Cup.

Washington competes alongside GMG Racing owner and team driver James Sofronas who swept the victories in both Pro-Am class races last year at COTA in the No. 14 GMG Racing Porsche 911 GT3 Cup. Sofronas has demonstrated similar winning performance in 2024 with Pro-Am victories at Sebring, Montreal and, in the most recent weekend he and Washington contested, at Road America in August.

The COTA Carrera Cup schedule began with a single practice session on Friday. Following qualifying Saturday morning, the first of the weekend’s two 35-minute races goes green at 3:40 p.m. CDT. Sunday’s race is scheduled at Noon CDT, setting the stage for the United States Grand Prix that follows. Tune into https://www.imsa.com/tvlive/ for livestreaming race coverage.

GMG Racing’s schedule of Winter Series track days and race events at The Thermal Club will be released in the coming weeks.

GMG Racing Fields Four 992 Cup Contenders at Laguna Seca Doubleheader

Beginning the second half of the Porsche Sprint Challenge USA West by Yokohama season the same way the championship-winning team started it, GMG Racing brings a four-strong entry of 992 Porsche 911 GT3 Cup teams and drivers to WeatherTech Raceway Laguna Seca this weekend for a Saturday and Sunday doubleheader on the 2.238-mile Monterey road course.

Kyle Washington continues his winning Sprint Challenge Masters Class campaign in the No. 232 GMG Racing Porsche 911 GT3 Cup and competes alongside a trio of teammates in the Pro-Am division.

Patrick Mulcahy in the No. 254 GMG Racing Porsche 911 GT3 Cup and Jay Barron in the No. 223 GMG Racing Porsche 911 GT3 Cup contest their second Sprint Challenge race weekends after encouraging debuts in the season-opening doubleheader at Spring Mountain Motorsports Ranch in Pahrump, Nevada in late March.

Mulcahy and Barron will be joined in the Pro-Am division by GMG Racing President and Founder James Sofronas, who makes his first start of the Porsche Sprint Challenge Season in his No. 214 GMG Racing Porsche 911 GT3 Cup.

“We ran four 992 Cup Porsches in the Sprint Challenge opener at Spring Mountain in March, and it is great to be back with the same amount of entries this weekend at WeatherTech Raceway Laguna Seca on IndyCar race weekend,” Sofronas said. “I have plenty of experience at Laguna, Kyle has a lot of laps there as well, and we look forward to helping Patrick and Jay, who are both in their first season in a top-level series as competitive as Porsche Sprint Challenge.”

Washington has been GMG’s Sprint Challenge “leader in the club house this season,” winning his first Porsche Sprint Challenge Masters Class race just last month at Utah Motorsports Campus. He charged from 10th on the starting grid to first in Masters in Turn 1 at the start of the weekend’s final sprint and held P1 to the finish. The victory was the third podium finish for Washington in the year’s first four Sprint Challenge West races. At the Spring Mountain opener, Washington secured an overall and Masters runner-up finish in the first race and a third-place Masters-class showing in the final sprint.

In his series debut in Nevada, Mulcahy was GMG Racing’s highest finisher in Sunday’s finale. He improved three class positions to finish fourth in the Pro-Am class and in the top-five overall and seeks his first Sprint Challenge podium finish this season.

Barron runs a select scheduled of Sprint Challenge races this year and suits up for just his second weekend in the series in Monterey after an encouraging debut at Spring Mountain. Finishing a solid 12th overall in both races, Barron’s top Pro-Am-class finish was sixth on Saturday in the Pahrump opener, and he gained a good amount of racing knowledge and an initial understanding of the 992 Porsche 911 GT3 Cup platform.

Sofronas makes his first Sprint Challenge start of the season after contesting the Utah and Sonoma Raceway rounds in the championship last year. An accomplished race winner and four-time World Challenge Champion, Sofronas already has two Pro-Am wins to his credit this season in Porsche Carrera Cup North America competition.

“The goal is to always finish first at GMG Racing, but my car in any series always comes last as far as preparation and planning back at our California races shops in Santa Ana, and later this summer, our all-new headquarters operation at The Thermal Club,” Sofronas said. “The GMG Racing team’s priority is always our clients first, but the stellar job they did in getting the three primary cars ready for Laguna Seca allowed me to compete as well.”

More podiums are the goal this weekend, but Sofronas competes with two different perspectives every time he takes the wheel alongside his teammates.

“We will all be racing to win and hit the podium, but first and foremost I am still a coach and mentor for all of our clients when we are on track together in any race,” Sofronas said. “It gives you an entirely different perspective that you can’t experience from pitlane or a data review, and I am really looking forward to getting an up-close view of Kyle, Patrick and Jay all weekend while also looking at our competition in the mirror!”

After qualifying Friday afternoon at 4:25 p.m. PDT, the weekend’s first race is scheduled to start Saturday afternoon at 4 p.m. PDT with the second and final 35-minute sprint going green Sunday at 9:40 a.m. PDT.

Both races and more from Porsche Sprint Challenge will be livestreamed on YouTube on the official Porsche Motorsport North America YouTube channel: @PorscheMotorsportNorthAmerica.
