It’s a template inspired by Hendrick Motorsports and five-time Cup champion Jimmie Johnson’s team.
Starting May 4-6 at Talladega, NASCAR will begin using an additional template for the C-post, the area of the car from the roof to the top of the rear quarter panel.
In February, NASCAR officials confiscated the C-posts of Johnson’s car during opening day inspection for the Daytona 500. At the time, Sprint Cup Series director John Darby said it was a violation outside of the templates.
NASCAR suspended Johnson crew chief Chad Knaus and car chief Ron Malec for six weeks and docked Johnson 25 points, but those penalties were rescinded on appeal by NASCAR chief appellate officer John Middlebrook, who upheld a $100,000 fine to Knaus.
The new template, which will be used at all tracks beginning with the May 6 race at Talladega, will cover more of the area of the C-post. Currently, the template—a grid that goes over the car—has four checkpoints that cover the C-post area.
“The new template is one step further in confirming the (required) surface of the racecar," Darby said in a statement released by NASCAR. Sporting News
