Yesterday, 4-8-97, NASCAR had a joint test with Bobby Labontes #18 InterState Pontiac, Mark Martins #6 and Ted Musgrave’s #16 Fords, and Sterling Marlin’s #4 Chevy at Daytona with restrictor plates(the rumor that restrictor plates would not be on the cars was wrong), looking for ways to slow down the cars aerodynamically. They tried many things including low drag combined with low down force and high drag combined with high down force but NASCAR would rather stay with what rules they have than do something that hasn’t been researched(4-8-97). Labonte and Marlin also tested on 4-9-97. Areas tested included the front air dam, rear spoiler(4″ and 8″), and spoiling the air on the roof and A-pillars(4-16-97)
