Have you even had your car or any newer (99-04) stang up to 140+? I can say that @ 148 I could have easily driven it with 1 hand...totally stable and safe feeling. I obviously didnt take one hand off lol, but just trying to show you how stabil it was.
Only things I was worried about was
A. Cops
B. Some random person pulling out, even though its HIGHLY unlikely
C. Random animal crossing
D. tire blowing out
Its a risk, but thats why iv only did it once....and ill never do it again in a bolton GT. When my car gets turbos I MAY do it on the way back from GA (LONG 3 lane highways seperated from the oposing lane by about 100' of trees.) And thats only because it will get to 150MPH a HECK of alot faster than before....less time im there the better.
Only other time Iv been that fast is receintly on the busa. Ran it to 150MPH....and it actually feels like a MUCH safer thing to do vs when I ran 148 in the car. And thats because of how fast it can be done.
Just a matter of <1/4 mile from 60MPH for the busa to get 150, but the car took 9 tenths of a mile.
I was babying the busa...hit it in 4th and short shifted to 5th (WAY early @100ish) and still got there rediculously fast....in the car I was going flat out giving it all she had.
