After seeing NASCARs aerodynamic rules produce 49 lead changes among 21 drivers in the recent NASCAR Winston Cup Series restrictor-plate race at Talladega, the International Race of Champions(IROC) is giving the package a try during its three-day test at Daytona International Speedway. Four Pontiac Firebirds that were shook down on Tuesday, the second day of IROC testing, were all equipped with a metal deflector across the roof of the car and a dirty spoiler. Round 1 of IROC XXV, which will feature 12 of the best drivers in the world in identically-prepared Pontiac Firebirds, will return to the World Center of Racing on Feb. 16 during Speedweeks. IROC test drivers Dave Marcis, Andy Hillenburg, Dick Trickle, Jim Sauter and 2001 IROC participants Scott Goodyear and Buddy Lazier ran in Tuesdays session. It is expected that IROC will have some kind of aerodynamic package in place for the 25th season of IROC next year. IROC testing continues today and is open to the public with access through DAYTONA USA, the official attraction of NASCAR(DIS PR)(11-14-2000)
