VINTON – The International Motor Contest Association has a problem with its stock car division that it’s planning to address on or about June 1 with a mid-season rules change. After June 1, 2021, any violation of these rules will result in a two-position post-race deduction.” “We’re not going to chase this issue all year long and allow it to get even worse before 2022. “Adjustable mounts need to be welded solid after June 1 as well,” he said. Root also noted that Stock Car or Hobby Stock bodies can no longer be mounted on adjustable mounts. “Due to the different body makes and models IMCA permits in the Stock Car division, 42 inches is plenty of rear tail height in that division and 40 inches for the Hobby Stocks is plenty of tail height in that division.” However, creative personal interpretation and ignoring some of these rules in combination with adjustable body mounts has forced IMCA to publish a dimension that all cars will be required to follow.”

All of these issues control the rear trunk height. “The height of aftermarket tailpieces has always been in the 20-23 inch range and we do not permit additional plastic to be mounted to the bottom of the tailpiece. “The rear tailpiece mounting rule, along with the rule that doesn’t permit any rear bumper bars to be lower than the tailpiece, has always controlled this issue,” said IMCA President Brett Root. Height measurements will be enforced across the top of the rear tailpiece in both divisions.
