The reason Tony Stewart has performed very well at Martinsville was due to the testing he did last year at the track. I happened to be at Martinsville at the time when Stewart tested, and his team hit on something. During that two-day test, all the things he was unsure about, they figured it out. Stewart figured out what brakes, springs and shocks they wanted to use and got the car to perform the way Tony wanted it to. Ever since that test, Tony has been amazing at Martinsville.
