On Tuesday, NASCAR competition officials announced new rule changes for the sport with the purpose of slowing cars down at superspeedways. The changes will be made to decrease Cup Series race car speeds by around 7 to 10 mph at each superspeedway event as a safety precaution.

The NASCAR officials informed each team this afternoon of the new rules. According to, the rule change includes a smaller tapered spacer for the sport’s largest oval tracks. The new regulations also call for tracks to reduce the openings from 57/64-inch to 53/64-inch.

The new rules state that cars must remove the wicker from their spoilers. In addition, the optional reinforced roll bar that is behind the driver compartment and near the rear wheel well is now mandatory. Furthermore, the rule changes will also require drivers to utilize two flashing brake lights when it rains. NASCAR has already implemented the same rule for its Xfinity Series events.

While the new rules won’t be implemented right away, they will be enforced in the next superspeedway race. However, that isn’t until August 28 when the Cup Series returns to Daytona International Speedway. The Coke Zero Sugar 400 is scheduled as the Cup Series’ last regular-season race. Following the Daytona race, a 16-driver playoff will begin as NASCAR looks to crown its next champion.

NASCAR Changes Rules Following Joey Logano’s Rollover Crash

After driver Joey Logano recently took flight in a rollover crash, officials began to discuss the rule changes. On April 25, Logano’s crash came at Talladega Superspeedway as he went airborne in a multicar stack-up. His No. 22 Team Penske Ford landed upside down as it skidded across the pavement on its roof. Thankfully Logano came away unscathed, but he spoke out asking for further safety precautions at superspeedways following his horrific crash.

On April 26, NASCAR Senior Vice President of Competition Scott Miller addressed the situation. He said that NASCAR competition officials would work with crew chiefs, drivers, and team engineers on how to best address the need for further safety protocols. reported that Miller said keeping cars planted to the racing surface in the event of a high-speed spin was “something that we’ve been working on and will continue to work on.”

The final superspeedway race of the Cup Series season will occur on October 3 at Talladega. Additionally, it will be the last time drivers race in the current-generation Cup Series model cars. The Next Gen race cars will make their first appearance next season at the 2022 Daytona 500.
