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 ! !
