Samples may be sent to lab of tracks choice for testing and results
from that lab final. No appeal. No exceptions.
Tires detected by vapor analyzer (Sniffer) exceeding 700 ppm track
benchmark will be considered contaminated and disqualified from
Tires tested 700 ppm in post-race tech will be tested maximum 2
more times in 10 minute window from initial test. A tire that falls
below that 700 ppm in 2nd or 3rd test will be passed. A tire failing
all 3 test will be considered contaminated and disqualified. This
ruling may be protested by driver or car owner only and requested
to have samples cut and sent to lab for full analysis at car owner
or drivers expense. Cost for this protest will be $150 (includes
testing, shipping & handling) and must be paid to track officials
and sampled before car leaves the tech area. At that time the race
results will be considered unofficial and no payout to protest cars
until results from lab testing are complete. Sampling process will
need to be cut by team’s groover and placed in sample bottle
by team member, bottle will be sealed by team member, and placed
in evidence bag never being touched by officials. Team will provided
