I thought that was the Traction Control lolYeah you gotta love it when you watch a guy and he is a solid 5th-6th place car for 12-15 laps of a feature. Then a caution flies and on the restart its like everyone is running on 6 cylinders except him. He's in a different zone.
Many people are always accusing guys of tire doping..
But in 2017, DIRTcar & WoO submitted over 1000 tires for testing and only one came back illegal. Of course that was Chris Madden at the World 100 at Eldora in September..
