In addition, the packs were far smaller in 1988 through 1990 until more teams mastered the nuances of this kind of racing and improved their cars (and drivers) accordingly. These walls absorb the energy of an impact better than concrete walls, while maintaining integrity better than traditional steel barriers. NASCAR introduces restrictor plates NASCAR began using carburetor restrictor plates in 1988 to reduce Daytona/Talladega speeds and two years ago made a technical switch to tapered spacers, which . At the high-speed superspeedways, track limits are marked by a double yellow line separating the apron from the racing surface.
