There are new wiring requirements per STT policy. #10 under requirements reads Advanced riders only must safety wire oil drain plugs, oil filter and oil fill caps. Intermediate must have a minimum of RTV or Silicone dab on the oil drain plugs and oil filter. ** Please note that if you spill oil on the track your day is over. This change in policy will decrease the likelihood of an oil related issue on the track which can ruin everyones day in attendance. Thank you! and I'll see YOU at the track.
