Ok, just to let you all know, the GT has the most power (550), NOT the SRT-10. Second, just like he said, around a track the GT can take these two easily. There's a reason it costs a buttload more than the other two and it isn't because of R&D either. The GT will hand the SRT-10 and Z06 their asses on a platter around tracks with many turns. In a straight line I'd still pick the GT for weight and traction advantages. I mean no disrespect to the Z06 nor the SRT-10, as I love the both of them. But let's be logical here, the GT wins.
