Not really, they are claiming certain cars are "track ready" but really they aren't. Nobody tracks a car with stock suspension, at least not if they expect to do well. The ZR1 and upcoming Z28 are the only ones current that advertise being "track" cars but everything else will need alot of work to really do well on a track.
Besides, 1/4 mile is the only thing that really matters. Unless you live next to a closed course track, everything is 1/4 or 1/2 mile.
