***The pair of K-PAX Racing with Flying Lizard Motorsports McLaren 650S GT3s led a wet morning warmup. Estre set the fastest time at 2:22.953 in the No. 9 McLaren, with Robert Thorne second in the No. 6 McLaren. O’Connell, Beretta and Catsburg completed the top five. A healthy volume of the field, 42 of the 48 GT/GTA/GT Cup entered, went out during the 15-minute session.

***Peter Cunningham’s No. 42 RealTime Racing Acura TLX-GT has been withdrawn from Sunday’s race. Suspension damage from contact incurred in Round 1 has proved too much to repair on site.

***Jeff Courtney had an incident during the morning warmup, and the JCR Motorsports team was working to repair the right front quarter panel damage to his No. 99 Audi R8 LMS ultra.

***Guy Cosmo is optimistic of driving further PWC races later this year if funding can be found. He’ll be coaching Walt Bowlin all year in the No. 23 M1 Racing LLC Audi R8 LMS ultra. Bowlin is confirmed to race in the St. Petersburg, Barber, Road America, Miller and either Sonoma or Mazda Raceway Laguna Seca rounds in the GTA category.
