I don't really run high speeds on a regular basis, I've only done the high speeds over 170 MPH two times. Other than that I've only had it up to 100 MPH a few times, I hardly ever even drive it. I do need to get it out more often, I've had it since October and it's only got 1,894 miles on it. It's not even been out of the garage since I had the new 285's put on the back two weeks ago and the only time it's been out since I put the Eibach springs on it was to go get the four wheel alignment done. I really need to get it out and see what the springs & tire's have done for it as far as handling and traction, I know it rides a hell of a lot better with the new springs.
