:...the Z isn't made for that. Just like the Mustang, Camaro guys, the only fast eclipse/talon/laser's are at the drag strip. Try running one of those TTZ's on the highway where real power come into play and see what happens. Your fast ET's are all in the launch, no top end due to drivetrain loss of your AWD. I admit, Z's are very poor dragsters because they don't launch as well but I didn't buy my Z to drag. If wanted to drag, I would've bought a Supra.
You say that the fast ET's are in the launch, but there are also many FWD's that have very good ET's (even RWD). DSM's can have top end too with the right setup. I do agree Z's being poor dragsters, but they are a very fun car...and the top end is unbelievable.
