All of the prep product lines mentioned earlier are excellent. You might want to consider using FTS EL preps, as many of the races won at dawgwood are with this product. Aside from being a great tire prep, Randy Waters with Appletree Karting is at almost every dawgwood race. He provides support and advice for the FTS prep line in real time at each race. As occurs at every track, the track surface conditions can change from week to week. Randy can help FTS customers with "at track support" every race........which is something very valuable to have.
