I would bet Penske since it is RG's backup car. FWIW if I were Robby I would sandbag in Practice #1 so the 7 could Q before the 77. That way if Robby kills the 7 somehow (think taking out the brake ducts at Montreal during Q run) PJ can withdraw and save the 77 for the 7's backup
just hoping... Not stating anything about their abilities, but remember Scott Speed, an excellent road racer himself, choked in 09 in the last turns and missed the show locking PJ in.
I think Kimi is also an excellent road racer, be he too has a learning curve.
Lally has been in stockers for awhile and Tony Ave is last years Trans-Am champ. He also has some time in stockers already. They both will do fine at Sonoma
Road racing a proper road racer is one thing and road racing a 'CUP' is something very different. Lally has been in the seat all year-no problem,Ave has been in a COT before.
It's Drissi with no stock car experience and the 37's equipment.(not know for good rr equipment)
