IRWINDALE, CA – The Sigma Engineering Pro Late Models will return for twin 50 lap main events on Sept. 19th to conclude the 2020 PLM Interstate Shootout.  The six-round series, a collaboration between Havasu 95 Speedway and Irwindale Speedway, will see the top 5 in final championship points receive a combined $5,000 in rewards.

On July 18th, The Sigma Engineering Pro Late Models descended upon the 1/3 mile at Irwindale Speedway for round #4 of the PLM Interstate Shootout. Prior to the event, Irwindale Speedway was proud to welcome longtime racing supporter Tri-City Towing as a partner to growing division. Tri-City Towing, along with owner Clay Wooster, contributed $200 per car start money to every PLM team in attendance. Following 50 laps of hard racing, and a late charge from his High Point Racing teammate, Dean Thompson, Trevor Huddleston grabbed his second Sigma Engineering PLM win of the season.

Headed into the September 19th finale, Huddleston holds a two-point lead over Thompson in the championship points. Rounding out the top five in points, Parker Malone, Mike Weimann and Robby Hornsby will look to put pressure on the High Point Racing duo during the night’s twin main events.
