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 ! !
