Teams Testing at Vegas Thursday

On-track action will start a day earlier than usual this week, with the NASCAR Sprint Cup Series testing the 2014 rules package on the cars on Thursday. Testing will run from 3:00-7:00pm/et. Changes to the rules package include statically setting the race car ride height and eliminating the pre- and post-race front height rules and inspections. Additionally, the 2014 package includes a square leading edge on the splitter, side skirt and rear fascia adjustments and an eight-inch rear spoiler. Finally, a 43-inch by 13-inch radiator pan will round out changes for 2014. (NASCAR)
