u talking Spec V? If so it is lighter, rear seat taken out, carbon ceramic brakes, bigger turbos and overboost function so better for tuning in theory, lighter forged rims for lower unsprung weight, diffuser revisions for better aero. So probably you'll find it about the same in a straight line, but better in the corners for track duty.
This is in RL though, in game it should be the same.
