Largest Restrictor Plate To Be Used For Coke Zero 400 Powered By Coca-Cola

Coke Zero 400

The upcoming Coke Zero 400 Powered By Coca-Cola will feature the largest restrictor plate since the one-inch mandate of restrictor plates back in 1988.

DAYTONA BEACH, Fla. – The Coke Zero 400 Powered By Coca-Cola NASCAR Sprint Cup Series race, the final event on the current asphalt of Daytona International Speedway, will feature the largest restrictor plate used since the one-inch mandate in 1988, the first year the horsepower-reducing plates were mandated for the NASCAR Sprint Cup competition.

NASCAR officials announced on Monday that NASCAR Sprint Cup Series teams will use carburetor restrictor-plate openings of 1 1/32 inches for the Coke Zero 400 Powered By Coca-Cola on Saturday, July 3 at 7:30 p.m.

“The upcoming Coke Zero 400 has the potential to be one of the most competitive races in track history,” Daytona International Speedway President Robin Braig said. “Having a larger size restrictor plate will give the stars of NASCAR even more horsepower to showcase a thrilling competitive race that our fans have come to expect at Daytona.”

Each restrictor plate contains four openings, which restrict air flow to the engine, thus slowing stock cars. Larger openings mean more air, and more speed.

Earlier this year, NASCAR mandated openings of 63/64-inch for the season-opening Daytona 500 – then the largest restrictor-plate openings since the one-inch mandate in 1988.

The Daytona 500, which was captured by Jamie McMurray, featured a record 21 different leaders who exchanged the lead 52 times.

“We think this will be a needed boost due to the additional drag we've picked up since switching from a rear wing to a rear spoiler,” said NASCAR Vice President of Competition Robin Pemberton.

Rule changes, announced Jan. 21, mandated switching from a wing mounted on the rear deck lid of NASCAR’s new car, back to a more traditional stock-car spoiler. The March event at Martinsville Speedway marked the first race for the new spoiler.

Carburetor restrictor plates are used only at Daytona and 2.66-mile Talladega Superspeedway. Events at those tracks are famous for their close competition.

The 52nd annual Coke Zero 400 Powered By Coca-Cola will be the final race on the current asphalt of Daytona International Speedway. Following the Coke Zero 400 Powered By Coca-Cola, the entire 2.5-mile tri-oval will be repaved for only the second time in its history.
