To be honest USAC is shooting themself in the foot. 1st all names were kept quiet on failed test, why? 2. Where did the new samples come from? I’ve been told usac went to the shops of teams to get new samples(this may not be true but usac could present all information to keep the rumor mill down and only facts inserted). 3. Although it is strange that all 4 tested positive for the same chemicals it’s not unlikely due to the fact there is a well known tire prepper that has helped all the teams in the past so it’s likely coming from the same place. They are taking no action on anything. The lab is wrong? Announce you’re no longer going to use them, but no. Instead it’s just no penalties and everything is fine. Their car counts will suffer and I also believe in time so will their fan counts. It’s unfortunate that groups will jeopardize all credibility for the almighty dollar.
