Two Xfinity Series teams receive L1 penalties post-Dover

The Nos. 3 and 7 teams in the NASCAR Xfinity Series received L1-level penalties after violations were discovered in teardowns at the R&D Center following Saturday’s race at Dover International Speedway. The No. 7 race-winning team was found to have violated section 20.14.2.h of the NASCAR Rule Book (rear suspension and trailing arm angles/pinion angle shims). Truck trailing arm spacer/pinion angle shim surfaces must be in complete contact at all points, at all times. Failure to adhere to that can create additional side force and is a violation.
