Air Pressures and Late Model Camber recommendations for Bristol Dirt Nationals
After reviewing our information from the 2021 events at the Bristol Dirt Track, we felt it was extremely important to get the following air pressure and Late Model camber guidelines posted for this event. The length, size, and speed of this track will be very demanding on the tires. We would encourage you to follow these recommendations closely. If you have any specific questions, please contact a Hoosier Representative.

Late Model Camber Recommendation – It is extremely important to reduce dynamic right front camber for the Bristol Dirt Nationals in order to equalize tire heat and wear across the full contact patch. This may require a longer RF upper control arm or other spension changes. All teams should monitor their tire temperatures regularly at the track. Teams should also pay close attention to RF upper fender clearance, all body bolt and fender brace placement, and LR body clearance.
