Thompson Speedway Motorsports Park has adjusted all five NASCAR Whelen All-American Series rulebooks with an amendment in the tire rules section, effectively immediately. The new section of the rules reads as follows:

Participants are responsible for competing on tires that satisfy all of the above rules. Tire samples may be taken at any time to be analyzed by an independent testing laboratory that has been approved by the respective tire manufacturer. The participant’s samples will be compared with control samples provided by the tire manufacturer. Any tire samples that are found to not match the factory control sample will be deemed illegal and the participant will be subject to the penalties outlined above.

Thompson Speedway Motorsports Park returns to NASCAR Whelen All-American Series racing on Sunday, September 1, with Back To School Night at the races and all five NWAAS divisions. Lock City Drift will be in competition for The Clubhouse Circuit Showdown.
