vibrations??
 

Does your car vibrate alot above 100 mph?? Last time i took it to about 130mph and the front end of the car was vibrating so much that it scared me. It just didnt feel safe. my hand was going numb from vibrations! Does your car feel like this too?

No such problem here, but suggest you add some details on your vehicle such as age, miles, mods, etc. In particular you might want to throw in info on the tires. OEM or not and approx miles on the tires. High performance tires tend to wear more quickly than your everyday tire, this is especially true of the OEM Bridgestones. I got about 18K out of mine before they were so bad that it felt like I was riding around in an old wooden buckboard.

Alignment or bad shocks. It could have even been the road.

Keep the speed at the track.

need for speed?

could be tire balance... I know when mine needed to be rebalanced it would shake bad around 70 mph.. I can just imagine at freakin 130.. No thank you ..

^+1 you need to balance your tires
