Here are a few of my friends that rode in my car when my tires spun in 5th gear at about 50mph on the highway. Chad: 918-633-7427 Alex: 918-277-2856 My name is John, so feel free to call them and ask. Both of these guys will vouch that it happened while they were in the car, seperate times of course. After that I decided to save tread, gas, and traction, so I turned down my boost.
