NASCAR expects to conduct a final test this week in preparation for allowing teams the option of installing a roof exit in cars. Winston Cup driver Michael Waltrip will participate in a test at Daytona International Speedway with the roof exit installed to determine if any aerodynamic issues exist with the new hatch, said Gary Nelson, director of NASCARs research and development center in Concord, NC. When the roof exit is finalized, teams will be allowed the option of installing it, but it will not be required, Nelson said. “If that test goes well, I already have the (technical) bulletin so the guys can use it,” Nelson said.( ThatsRacin.com )(9-6-2003)
