NASCAR Makes Rule Changes After First Daytona Test

Following the first day of preseason testing at Daytona International Speedway, NASCAR has made some rule changes, according to FoxSports.com.

NASCAR has increased the restrictor plate size from 29/32 of an inch to 15/16 of an inch to give the cars more horsepower and make them less stable for prolonged tandem drafting. They also lowered the pressure relief valve from 30 psi to 25 psi and decreased the size of the grille opening by one inch on each side, bringing the size down to 3.5 inches by 18 inches. This should make the car require more air, which means they will have to move out of the tandem draft more often.

NASCAR spokesman John Darby said that fan outcry over the tandem draft was a reason for the changes.

Additionally, NASCAR banned communication with other drivers during drafting. Under the new rules drivers are allowed to communicate with their spotter and crew during a race; they cannot communicate withother drivers, spotters or crewmen from other teams.

In restrictor plate races last year, drivers could communicated with other drivers, and many of them made deals to tandem draft with others.

Darby said:

There was a point where it got so confusing to them that they actually lost focus on what they were doing and felt much better if we could back that off somewhat and get it to a standard or more common communications between driver and spotter and driver and pit crew as we’ve known it in the past.
