Rules - Heads Up Rules

MDSS Trucking Mean Street is a 1/8th Mile Heads Up Class, running on a .400 pro light tree. The goal of this class is to bring into heads-up racing as many as possible people who have never heads-up raced, by keeping the class "entry level", inexpensive, competitive and fun.

Rule Changes

This is a brand new class which has never ran before at Ozark Raceway Park, and since it is new you should expect some minor adjustments to the rules to keep a fair playing field for all participants. There will be a mid season review of these rules. After the 3rd race we will close any loop holes we missed. This is in an effort to keep the competition tight through as many different combinations as possible. Ozark Raceway Park reserves the right to change or modify the rules as necessary with no less than 30 days notification.
