ive done 165, and i wouldnt recommend it unless you have an aerodynamic body kit, are lowered, have big grippy tires, and do it on a nice road while vowing never to do it again...

Removed - I misread your post.

Before it went down for the rebuild, I was running 122 mph average in the 1/4 and always had some sort of vibration. Different driveshafts had different levels of vibrations but even on the stock shaft, there was some vibration at that speed under stress. Normal... Look back at the history of ALL mustangs. The chasis construction is one of the key elements that made this car affordable compared to other 'sports cars' even in the 60's. It will never handle like more expenive sport cars at 100+ and that's just the way it is. Still, pretty damn impressive for a $30K car though.

lost in kuwait

i work here in kuwait and we have some nice long flat roads i had the same prob as you in was in 1 of my stock tires put on a set of t1s took care of it also i have to say dont try above 145 with out some work it gets pretty light i just added 2" lowering kit and a front air splitter and it made a huge diff so be safe and keep it above 6000

141 max for me, no shaking at all, awesome handling at that speed too

140mph, lots of wind noise and the hood was vibrating enough for me to worry about it blowing off, but otherwise rock solid especially since the pavement wasn't the smoothest.

Sleeper05, i am just curious how you know that you were going 165...not calling you a liar, just curious. i thought our speedos only went up to 145 and we were aerodynamically governed to around 155. now i have past my speedo past the 145 mark on Beltway 8 and it was very smooth

Well I am sure he has retuned is car where it is not limited to 155----------plus he could be like me and have a 200mph speedo...standered in a saleen

Timmay!!!

There is no limiter on the GT. Only drag slowing you down.
