Ditto on high speeds with the stock tires: DONT DO IT!!! The stock tires are not rated for such high speeds. I don't know about y'all, but with the stockers, when I'd get up around 95+, the front end would start to feel a little light and "floaty". Changing to z-rated 17" tires completely eliminated that problem. So now at 100+ (at a track), it handles just fine..going straight at least!
As far as top speed. Well, on the dyno at least, in 4th gear with my auto, I saw it hit 145 @ 6K rpms with stock 3.31 gears. Of course I have the speed limiter removed and an aftermarket driveshaft. With a .7 reduciton in gear ratio in overdrive, 175 would be thoeretically possible for a short time.
There's not really anywhere around here though where you can safely drive that fast on public roads, so I don't try. (well, I can think of one place
)
Keep it safe, everyone!
