It's gonna come down to whoever hooks better. And if you both do it's going to be one close race. Good luck

Last time I checked, the GT came with a 2.73 rear... The IROC has the same right? If this is so, neither of you should have much of a hooking problem... I'd say it comes down to how well he can shift.
