Nascar Makes Changes

Nearly a month after NASCAR’s unprecedented wind-tunnel testing of the three competing models in its elite stock car series, the sanctioning body announced what it called slight modifications to all makes of cars.

Effective May 4, a minimum ground clearance of 4 inches on the front air dams of all three models - the Chevrolet Monte Carlo, Ford Thunderbird and Pontiac Grand Prix will be required, up from 3.75 inches.

NASCAR also ordered that rear spoilers be adjusted to 5.75 inches high, down from 6.25.

Effective May 17, in time for the CocaCola 600 at Charlotte Motor Speedway, NASCAR has ordered the front air dams of Thunderbirds and Grand Prixs be lowered another quarter inch, to 3.75, and the rear spoiler be modified to 6 inches high. Rules for the Monte Carlos and other eligible models will remain the same.
