In Prototype: #10 Velocity World Wide. The Taylor Brothers (their Dad) and Max the Ax. If you've not seen Grand-Am Boys beastie boys video on why Jordan and Ricky are a riot search grand-am boys on youtube they've done 2 music videos.
In GTLM- C7.R - Nuff said (because racecar)
In GTD: 007 Aston Martin James is driving. They all got together in Tuxes for a photo op with the car. Also Brandon Davis is a friend from iRacing. He's cool as hell and a genuinely great guy.
In Prototype Challenge - Alex Tagliani and American F1 hopeful Conor Daly are sharing a ride. I'll be pulling for them in PC. Daly is trying to ink a deal with an Indy Car team but nothing has been finalized.
