***While the TUDOR United SportsCar Championship had a pre-Circuit of the Americas Balance of Performance adjustment, no changes have occurred in the Continental Tire SportsCar Challenge prior to the penultimate round of the season.
***Matt Plumb, in the No. 13 Rum Bum Racing Porsche 911, and Adam Isman, in the No. 18 Rennsport One Porsche Cayman, led Wednesdays’ GS and ST class practice at Circuit of the Americas. A second session runs from 9:20 to 10:05 a.m. on Thursday before qualifying Thursday afternoon. Times from the first session are linked here.
***Multimatic Motorsports has repaired the same No. 15 Ford Shelby GT350R-C chassis damaged in an accident at Virginia International Raceway for Scott Maxwell and Billy Johnson. The pair had raced the previous generation Ford Mustang Boss 302R at VIR.
***Unfortunately for the team’s second car, an ST car hit Jade Buford during Wednesday’s first practice. It will force the Multimatic crew to make small repairs to the left side door panel of the No. 158 Ford before Thursday’s running.
***Both Multimatic cars are running tribute stickers to the late David Stone. The decals premiered at VIR, and continue into this weekend.
***Ahead of the team’s home race in Austin, CJ Wilson will be on site to support his team for the first time since Mazda Raceway Laguna Seca in May. The CJ Wilson Racing team, which fields two ST class Mazda MX-5s for the first time since Daytona, also won its first Continental Tire race at the track in 2013 with Marc Miller and Stevan McAleer.
***Rebel Rock Racing will run in GS for the first time since Sebring, with Ruben Pardo and Carlos Contreras moving up from ST to drive the No. 08 Porsche 911. Andy Lally, Cameron Lawrence and Dylan Murcott had been in the car at Daytona and Sebring.
***Rebel Rock will still run two ST class Porsche Caymans, with new arrival Remo Ruscitti and team principal Jim Jonsin in the No. 87 car, and Nate Norenberg and Fred Poordad in the No. 88 car.
***Ruscitti’s switch to Rebel Rock from Rennsport One leaves the No. 18 Porsche Cayman there with another different lineup, this time Adam Isman and Cavan O’Keefe, for the final two races of the year. Isman raced with the team through Watkins Glen and O’Keefe makes his first start of 2015.
***Jason Rabe, who has driven all season with Ethan Low in the No. 31 Bodymotion Racing Porsche Cayman, was on the verge of not racing at his home track, and where he made his series debut last year. With a late deal completed in the last week to continue, Rabe will finish out the season.
***The revolving door of co-drivers at LAP Motorsports now sees Aaron Nash alongside Zack Meyer in the No. 37 MINI JCW, with the same lineup of Ramin Abdolvahabi and Tyler Stone continuing from VIR in the No. 52 MINI.
