Story By: JUSTIN SNYDER / PORT ROYAL SPEEDWAY – PORT ROYAL, PA – On December 10, 2021 at the Performance Racing Industry trade show several of the national sanctioning bodies of Super Late Model racing got together to implement a common set of rules for all of Super Late Model racing to get everyone on the same page so that drivers wouldn’t have to build different race cars for different series.
In an effort to coincide with those national tours, the Port Royal Speedway will implement these rules for the 2022 season.
The rulebook will be updated in the coming weeks to reflect these changes, but drivers can use the 2022 Lucas Oil Late Model Dirt Series rulebook as a guide when making changes to their race cars.
The key issues include the following:
Rear travel limiter: Commonly known as the “droop” rule, postrace rear deck height must not exceed 51 inches (checked with both rear tires off the ground). Failing inspection results in disqualification that disallows a driver’s time trials or puts the driver to the rear of the previous race’s finishing order.
Weight rule: 2,350 pounds with driver after races; cars are allowed a pound-per-lap burnoff for feature events
Tire sizes: Cars must be equipped with a 28.5/90 circumference tire on left-rear and front tires; the right rear circumference must be 29.0/92
Body skew: The measurement of the left-rear quarterpanel from the center of the hub to the rear of the quarterpanel should not exceed 54 inches. Measuring 6 feet from the left-rear quarterpanel to the right-rear quarterpanel, 8 feet forward along the right-side door, the diagonal measurement from that point to the top of the left-rear quarterpanel requires a minimum of 118 inches.
Decking: If the hood is drooped, the deck must remain flat. If the hood remains flat, a drop of the deck will be allowed (maximum 2 inches). If the interior is dropped, the hood and fenders must remain flat behind the air cleaner.
Quarterpanels: Plastic quarterpanels will be allowed on the right side of the car only (disallowed on the left side
