NASCAR Makes Rule Changes For Sonoma
NASCAR issued a technical bulletin to teams outlining rule changes for the upcoming Toyota/Save Mart 350 at Infineon Raceway. According to the bulletin:
Ground clearance for all side skirts has been increased by ½ inch. Right side skirts must have a minimum clearance of 4.5 inches/maximum clearance of 5 inches. Left side skirts must have a minimum clearance of 5 inches/maximum clearance of 5.5 inches. This is the next step in looking at the aero package for intermediate race tracks.
Both the right and left side rear sway bar arm connecting links must be perpendicular to the ground from all viewing angles when car is at ride height. This is an effort to maintain consistency in rear sway bar setups.
