A total of 28 entries are set for next weekend’s Pirelli GT4 America season opener at Sonoma Raceway, which will kick off SRO America action across multiple sports car and touring car racing championships.

The entry list, released on Friday, is comprised of six Silver class entries, 11 Pro-Am contenders and ten cars for the Am class, with one entry — the No. 53 AutoTechnic Racing BMW M4 GT4, yet to receive an category classification.

Reigning Silver class champion Zac Anderson returns to the No. 51 AutoTechnic BMW, but with new co-driver Colin Garrett, who steps up to GT4 competition after winning the 2023 TC America title.

GT4 America runner-up Michai Stephens will also have a new co-driver in Jonathan Neudorf as Stephens switches to TechSport Racing in the No. 23 Nissan Z NISMO GT4.

The race-winning pairing of Kenton Koch and Kevin Bohem return in the No. 97 Random Vandals Racing BMW, while Tyler Gonzalez joins John Geesbreght in the No. 68 Smooge Racing Toyota GR Supra GT4 EVO, alongside Daniel Hanley and Parker Thompson, who also back in Toyota machinery.

The all-Canadian lineup of Demi Chalkias and Jake Cowden will be making their series debut in the No. 34 JMF Motorsports Mercedes-AMG GT4, which no longer holds an operational partnership with Conquest Racing.

While 2023 Pro-Am champions Matt Travis and Jason Hart have not returned to defend their title with Nolasport, BimmerWorld’s James Walker Jr. and Tyler McQuarrie, who finished runner-up last year, are back in their BMW.

Other familiar pairings include Gray Newell and Roman De Angelis at the Heart of Racing Team (Aston Martin Vantage GT4), ACI Motorsports’ Curt Swearingin and Kay van Berlo (Porsche 718 Cayman GT4 RS Clubsport) as well as the TechSport duo of Eric Powell and Colin Harrison (Nissan).

As previously announced, Blackdog Racing will step into GT4 America competition, also with a Nissan, for Tony Gaples and multi-time former series champion Michael Cooper.

Flying Lizard Motorsports, meanwhile, fields a Nissan for the Canadian pairing of Damir Hot and Stefan Rzadzinski, with the Arizona-based team also entering an Aston Martin for Tom Dyer and Todd Parriott.

Former Honda Racing Corporation USA factory driver Ryan Eversley will make the switch to Toyota machinery, having been confirmed for the season in Precision Racing LA’s Toyota GR Supra GT4 EVO alongside Harry Cheung for the pair of 60-minute races at Sonoma.

Other notable entries in Pro-Am include former NTT IndyCar Series driver Matheus Leist teaming up with Michael Auriemma in the No. 89 RENNtech Motorsports Mercedes-AMG GT4, alongside the team’s sister No. 43 P1 Groupe-backed Mercedes-AMG.

The Am category will see BimmerWorld’s James Clay and Charlie Postins pursue a third consecutive class title in their No. 36 BMW, while Nick Shanny and Terry Borcheller are back with Carrus Callas Raceteam, but swapping its previous Toyota for a BMW.

Heart of Racing will continue with its all-female-driven Aston Martin, with Hannah Greenmeier joining Hannah Grisham in the No. 26 Aston, while Rotek Racing and Random Vandals will each field a Porsche and BMW, respectively in the category, along with a continued series presence from Nolasport, KRUGSPEED and OGH Motorsports.

Track activity kicks off with a two-day test at Sonoma on Wednesday and Thursday, followed by official practice sessions on Friday, prior to qualifying and the pair of races on Saturday and Sunday, which will be streamed live on SRO’s GT World YouTube channel.
