A new NASCAR short track rules package is expected to be announced for 2020
A new rules package was introduced in 2019. Away went the tiny spoilers, in came the very large 8 inch spoilers. The downforce was back in a big way.
It significantly improved the product on tracks larger than 1-mile. The first race at Texas Motor Speedway saw 1,713 more green flag passes than the same race in 2018, a near 100% increase.
However, short tracks suffered, across the board.
The first race at Richmond Raceway saw a 32% decrease, Bristol Motor Speedway saw a marginal 5% increase, Martinsville Speedway saw a 1% increase and ISM Raceway saw a 20% decrease in green flag passes with the new NASCAR rules package.
At the short tracks, the corner speeds are way up. It made it extremely difficult to pass, especially on the one groove race tracks like Martinsville.
The increased downforce has increased the corner speed which in turn has increased the wake of dirty air. That makes it’s difficult to work under a driver off the corners of a short track and race them into the next corner.
NASCAR is now in the middle of a development freeze. That was agreed upon with the sanctions and the teams. The idea was to save the teams some money as a totally new car is on the way for 2021 which will make most development on the old car, totally irrelevant.
But, there’s still a whole season left to go with the old car. There’s some issues with it, particularly on short tracks.
Steve Phelps on his openness to adjust short track rules in 2020
“I think we’ve over delivered on the intermediate tracks, and we will make sure that when we get to Phoenix in the spring, and some of the other racetracks that are short tracks, that they’re going to have better racing,” NASCAR president Steve Phelps stated in November 2019.
“We’re going to work with our teams in order to figure out how we do that, work with our OEMs to figure out how we do that. Everyone knows I’m not an engineer, I’m not going to play one now.”
“I am confident, having spoken to people who are far smarter than I am in this space, that there are things we can do. And I think our teams are excited about trying to partner with us to figure out what that looks like.”
“There are people far smarter than I am that could figure that out. Yes, could we go to something that is a lower downforce package and do we think that will probably be one of the answers that we could look at to be successful on the short tracks? Yes.”
“Whether it’s cutting off the spoiler, other opportunities for us to take some of the downforce off there, those are things that we’ll explore. No specific timing,” Phelps stated last year.
NASCAR is expected to adjust short track rules
According to Adam Stern, NASCAR is expected to announce a new short track aero package ahead of the 2020 season.
The teams have agreed to make adjustments to the package, despite the previously mentioned freeze on development.
The adjusted package is likely to bring less downforce to the short tracks. A smaller rear spoiler and smaller front splitter are expected to be the changes.
The higher downforce package is likely to remain consistent from 2019 to 2020 in regards to tracks 1-mile and larger.
The first NASCAR short track race in 2020 will take place at ISM Raceway on March 8, 2020. It’s a track that took a lot of criticism after the race last fall. The same track that will host the 2020 championship finale.
