The GS class is poised to nearly double in size for this weekend’s Continental Tire SportsCar Challenge round at Lime Rock, following the return of a number of teams to the top class for Saturday’s two-hour and 30-minute race.

The entry list for the sixth round of the season sees a provisional 35-car field, including eight cars in GS, which saw a record-low four car starting grid at Canadian Tire Motorsport Park earlier this month.

ENTRY LIST: Lime Rock

The No. 35 CJ Wilson Racing Porsche Cayman GT4 Clubsport returns with Tyler McQuarrie and Till Bechtolscheimer, while the No. 99 Automatic Racing Aston Martin Vantage GT4 of Rob Ecklin is listed, after also missing the CTMP round.

Both of the Team TGM Porsches, meanwhile, are also entered, after the Ted Giovanis-owned team withdrew prior to the start of official track action at CTMP, over an alleged Balance of Performance advantage given to the Ford Shelby GT350R-Cs.

Multimatic Motorsports’ Scott Maxwell and Billy Johnson picked up their second victory of the season in Canada, ending Bodymotion Racing’s Trent Hindman and Cameron Cassels’ three-race win streak in their No. 12 Porsche.

While remaining at 27 entries, there are a number of changes to the ST field heading into Connecticut.

The No. 34 Alara Racing Mazda MX-5 is not listed, although another Mazda, from Riley Racing, is set to take its place, with local drivers AJ and Jameson Riley set to pilot the entry.

Elliott Skeer and Sam Adams have been replaced by Lee Carpenter and Kieron O’Rouruke in the No. 7 Rebel Rock Racing Porsche Cayman, with Phil Bloom in the No. 18 RS1 Porsche, instead of Remo Ruscitti.

There’s also been changes to the Mini JCW Team’s lineup, while Ryan Eversley is set to continue in the No. 93 HART Racing Honda Civic Si.

Steve Eich, who missed the CTMP round, meanwhile, is back in the No. 92 HART entry alongside Cameron Lawrence.

Track action for the Continental Tire Challenge gets underway on Friday, with the race set for Saturday at 10 a.m. ET.
