Both are at full effort cornering (at different tracks), though the later one is probably at higher Gs as a result of the coil overs. 
While i was wrestling with my stock suspended C4 pitching and lurching all over the track, i would catch glimpses of Garys' yellow custard. Having the same type of coilovers as yours it would just sit solid and flat. I think anyone who is serious about doing track work in a Corvette that is the only way to go.
it's definitely on my to do list:drag:
