Sources tell Sirius Speedway today that NASCAR could mandate a larger restrictor plate for this year’s running of the Daytona 500.
Sprint Cup Series racers were required to run a 31/32” plate at Daytona and Talladega last season, but multiple sources who attended a meeting with NASCAR today say the sanctioning body may allow a bigger plate this season, in an effort to boost horsepower, torque and throttle response.
That move would reportedly come as part of a package of changes that could include aerodynamic modifications to the rear window area, and a switch from rear wings to old-style rear spoilers. A number of procedural changes are also bring discussed, including the abolition of no bumping zones and the so-called “yellow line rule” at both Daytona and Talladega.
A spokesman for NASCAR declined to comment when asked about the restrictor plate change earlier today, saying that meetings are ongoing with drivers and teams, and that no final decisions have been made.
