NASCAR Sprint Cup Teams Test At Daytona International Speedway
Teams Run Different Rear Spoiler Sizes To Help Determine Solid Baseline Aerodynamic Package For 2012 Preseason Thunder Test At DIS

Teams participating in Tuesday’s test included Hendrick Motorsports (Dale Earnhardt Jr. and Aric Almirola); Roush Fenway Racing (David Ragan and Marcos Ambrose); Joe Gibbs Racing (Joey Logano); Michael Waltrip Racing (Martin Truex Jr.); and NEMCO Motorsports (Joe Nemechek).

After the track was dried following an early morning rain shower, teams first got on the track at 11:45 a.m. The initial restrictor plate size was 29/32 inch and the initial spoiler size was 4 ½ inches tall, 63 inches wide, which was the same spoiler size for last July’s NASCAR Sprint Cup Series race at Daytona.
