“NASCAR ordered up plenty of wind tunnel time before the Craftsman Truck series went to its first two-mile track, California Truck Speedway, for the No FEAR Challenge last weekend. As a result of the various tests, the aero package for the trucks was altered significantly and, perhaps, permanently. First, the front valence ground clearance was raised from 3.5in. to 4.0in. and the kick-out increased from half and inch to one inch. The maximum width of the front at the fender flares was increased from 77in. to 80in., and teams can run an optional wicker bill in the leading edge of the front wheel well opening. Also, the rear spoiler was raised an inch from six to seven, with a 55-degree minimum angle. There was naught but praise for the revisions at Fontana, and they will likely become law.(MCI Racing News/NASCAR Fans)(10-31-97)
