8. VEHICLE LOG BOOKS
The Vehicle Logbook for
each PRL Race car remains the property of PRL and will contain not only

issued to the new owner. When the logbook has been filled, a new one
shall be requested from the VDI. The logbook shall be presented at
Technical inspection at each event entered. All PRL cars are subject to
normal safety inspection. Each entrant is required to have in his
possession at every race the PRL Logbook to aid scrutinizers in
inspection. Additionally, scrutinizers will check official seals. A
competitor may not be barred from competing at a specific event if a
seal is broken, or damaged, but the part may be considered suspect and
will be treated as such and will be noted in the PRL Logbook by the
Scrutinizer. If engine manifold, valve cover, timing chain cover, or
oil pan seals are broken, damaged, or missing, the engine shall be torn
down for testing and resealing at the competitor’s cost prior to the

9. WEIGHT
The cars competing weigh
will be dependent on class and to be determined after qualifying and
either of the races. Any of the top five finishers may be signaled to
go to the impound area and be weighed before going to their pits.
Failure to go to impound will result in disqualification for that
session. If it is a qualifying session the driver will be gridded at
the rear for the race and lose all qualifying points. If it is a race
session the driver will lose all points for that race. Cars can also be
arbitrarily selected, as deemed necessary, at each event to check that
they meet minimum approved weight. Failure to make minimum weight at
the completion of a race will result in loss of all points for that
race.
