My STS is not z-rated. Does anybody know its top speed?
also, is there a difference between my top speed and z-rated top speed?

OK, I can understand the tire difference, but is the actual speed of the
non-z-rated STS limited/governed differently than a z-rated one?

If it says H rated on your door the computer limits it to @130, if it says V rated you'll do around 150.

I've always thought the best part of driving this car is the WOT acceleration between 40 and 90, but that's just me.

Watch out for the man and remember it is an old car, if your tires aren't new or have any plugs in them, take it easy for yourself and the rest of us. Things can go south fast over a hundred miles per hour!
