Thirty six cars are set to take part in this weekend’s IMSA Continental Tire SportsCar Challenge Continental 120 At The Glen, with 15 GS and 21 ST machines on the pre-event entry list.

The series resumes after nearly a two-month break since the last round at Circuit of The Americas in early May.

ENTRY LIST: CTSC Watkins Glen

The GS class is headlined by the Bodymotion Racing duo of Trent Hindman and Cameron Cassels who jumped into the points lead after the last round at Circuit of The Americas.

Hindman and Cassels’ Porsche Cayman GT4 Clubsport is one of the five of the 2016 GS-spec Caymans in the field. Two additional Caymans from Team TGM and RS1 are of the fully-GT4 spec Porsche Cayman GT4 Clubsport MR variety.

Once again, Team TGM has both varieties of Porsche entered with Guy Cosmo and Ted Giovanis listed as the drivers for both cars.

Back for their second race of the season are Robin Liddell and Matt Bell in the Stevenson Motorsports Chevrolet Camaro GT4.R, which made its series debut at COTA last month.

Absent from the entry list after contesting the first three rounds is the No. 3 TRG-AMR Aston Martin Vantage of Craig Lyons and Kris Wilson, who were 13th in points.

Another change from the GS ranks is the return of Al Carter to the driving lineup for Automatic Racing.

Carter, who had contested Daytona and Sebring with the team, will be back alongside of Rob Ecklin Jr. in the No. 99 Aston Martin this weekend, replacing Steven Phillips who was in the car at COTA.

The 15-car GS field is comprised of machines from five different manufacturers: Porsche (7), McLaren (5), Aston Martin (1), Ford (1) and Chevrolet (1).

The ST class sees the addition of five cars from the 16 that were entered last month at COTA.

Devin Jones and Drake Kemper return to the class in the No. 31 Bodymotion Racing Porsche Cayman after missing the COTA race.

Matt Dicken and Corey Lewis are making their first start of the season in a Cayman entered by Strategic Wealth Racing, while David Askew and Aaron Povoledo will team up in a RS1-supported Porsche Cayman for the next two rounds, as part of a joint effort also involving Kensai Racing.

Another new addition is the No. 47 Team Octane MINI JCW with Canadian drivers Alain Lauziere and Adam Isman set to take the wheel this weekend, and the Riley Racing Mazda MX-5 of AJ and Jameson Riley.

Six different manufacturers are represented on the ST grid with entries from Porsche (7), Mazda (5), MINI (4), BMW (3), Nissan (1), and Audi (1).

The Continental 120 At The Glen is scheduled for 2:25 – 4:25 p.m. ET on Saturday with live streaming coverage at www.IMSA.tv.
