Pure Stock Class Rules

Chargers, to name a few, have a wheelbase that is equal to or is greater than 112” and make excellent

driver will forfeit all money, contingency winnings and trophies
for the feature as well as all points for the
season and a $500.00 fine which must be paid before the driver
or car will be will be allowed to compete
again at BRRP. The reason for setting these rules is to
keep a level playing field that is fair for all. We intend to follow the spirit, as well as the letter
of these rules and expect you will do the same. Cars are also subject to, and are
required to comply with the General Rules of BRRP as published. Car owners, drivers & crew personnel are
advised that BRRP does not ensure that competing cars Comply with all documented rules on a
week to week basis or at the time they are technically Inspected. It is up to the individual
competing the car (owner/driver) to comply with the rules as written. A technical inspection does
not constitute that a car is in compliance with all documented rules.
Rules, components or procedures
specifically not mentioned as being allowed are “ILLEGAL” unless Approved by BRRP. Teams that have any
doubts or questions with regards to the legality of using any New product, procedure or an
undocumented component need to contact a BRRP official for clarification on use with regard to a
specific class. BRRP reserves the right to modify the rules at any time to keep all manufacturers
brands competitive, ie GM, Ford, & Mopar. No express or implied warranty of safety
shall result from compliance with these rules & regulations. The rules are intended as a guide for
the conduct of the sport & in no way are a guarantee against injury or death to participants,
spectators, or others. If a car is found noncompliant with
existing rules under a protest situation, they
will be penalized accordingly. Reminder – all cars must be technically inspected before allowed to
race. Racing can be dangerous and it is the driver’s responsibility to inspect the track
surface and facility prior to entering a race. If the driver
feels there are any unsafe conditions that he feels
may put him at risk, he should not compete. The driver should document concerns in writing and
submit them to the BRRP office for review. This brings
us to the most important rule at BRRP ‐ ‐‐‐‐ Have Fun ! ! |
