How Will the NASCAR Cup Series Teams Tackle the Bristol Dirt Track?

In the 2021 NASCAR Cup Series season, the paddock is set to race at the Bristol Motor Speedway. However, instead of the regular track, the grid tackles the dirt surface. Of course, all the cars will be adequately modified to extract the best performance on an unfamiliar surface.

In addition to that, the cars will also have a 750bhp engine package for the race. Furthermore, the cars will also undergo a few physical changes. Obviously, there could be a danger of the dirt potentially entering the car and damaging it. As a result, all teams will likely modify their respective cars to avoid such instances.

What do the NASCAR Cup car changes include?

First and foremost, rumor has it that none of the Cup cars will sport a splitter for the Bristol dirt race. However, the teams can add a few extra bars of support on the right side of the cars. Additionally, all the various ducts of the cars will be covered by screens. This possibly a manner to bring some form of comfort for the drivers.

Other upgrades include a solid, magnetic steel plate option in front of exhaust pipes. The plate’s sole purpose is to keep the dirt from out of the exhaust pipes. Furthermore, the cars’ hood will have an 18in-by-6in debris deflector installed on it. Meanwhile, there is also a chance that the existing decklid hinges can be reinforced.

Additionally, NASCAR could opt against a rear spoiler in order to prevent dirt build-up. Truthfully speaking, the dirt could be very problematic, especially from an aerodynamic point of view. All in all, NASCAR is pulling out all the stops to ensure that the 2021 Cup Series race at the Bristol Motor Speedway dirt track, runs as smooth as possible. Of course, the season itself kicks off with the Daytona 500, with the Bristol race still some time away.
