160mph is about the height of it with stock gearing and 6500-6600 redline. Your car will be fine at that speed as long as your tires are in good shape and inflated correctly. Mine felt fine at that speed and I only had sways at the time as far as suspension goes. Just make sure you give yourself room to slow down as it takes a WAY longer distance than from 60 or 100. Good luck.
