From the above comments about some fighting and not fighting it it being reputation:
There is way more at stake than reputations. The monies they won at the various WRG races will not get paid as well --- plus the fines the were hit with.
From the Dream:
All five have been disqualified from the event, including the loss of all purse money and championship points earned during the event, fined $1,000 and penalized 1,000 DIRTcar Late Model points for the 2016 season. The total penalty, including loss of money, fine and the cost of the tire analysis was $19,630 for Sheppard, $4,655 for Satterlee, $7,630 for Owens, $10,930 for Thornton and $6,105 for Bloomquist.
And then Bloomquist won the Firecracker 100 and that was a WRG race so I believe they held is $30,000 check from that race as well.
So I think these guys have a little more at stake than their reputation.
