I could not get it to hook up with even 13psi tire pressure. And the backend of the car would feel like it picked itself up in the air. So my car would end up in the other lane. I was trapping 127+mph at the end of the track. No way in hell I'm letting off the gas until the finish line though,so I want to try these BFGs and see how well they work compare to those M/Ts... if I can make them last that long. Heh.
