Chevy drivers were nearly 10 mph slower in qualifying setup during this week’s NASCAR shock tests, according to Chevy crew chiefs. NASCAR may go to a slightly larger restrictor plate for the Daytona 500 if its planned shock rules go through. Current plate holes are 29/32nds of an inch in diameter. If the plans don’t go through, then NASCAR could go to an even smaller plate. NASCAR officials told teams at Talladega they will probably order the same “stock” shocks for the Daytona 500 as for Daytona qualifying( PitNow )
