For those not afraid to push it to the limit, how fast have you got your Z's up to? I've been 150 mph in mine so far and I must say it skates up there pretty easy. It feels quicker than my SRT8 at times although I know its not faster on any scale in which I've topped 170 mph plus a few times and 150 mph plus so many times I can't remember. Z just glides at those upper speeds and feels one with the road, but I don't trust it just yet, I haven't had it long enough and don't know it well enough to go past 150 mph, but just wanna know whats the limit its been pushed to.
