motors even among the same manufacturer. Tech officials will, to the best of
their ability, determine what the permitted ratios and lifts are. It will be up to the
individual competitor to verify with the tech officials prior to competition what the
legal ratios and lifts are for their particular motor.

***PLEASE NOTE***
The above weights were established through a consensus of the Track Owners
throughout the region. The intent of these weights us to provide equal competition
among the motor packages. Track Officials reserve the right to make weight adjustment
to any motor package that appears to have an advantage. We suggest you utilize the
motor package that makes the most economic sense for you. If you are a new
competitor or a current competitor looking to change motor directions we recommend
the Ace motor package.
