OLD DOMINION SPEEDWAY
MINI-MODIFIED DIVISION
2012 RULES AND REGULATIONS
Version MM2011.A Effective 1/1/12
PRINTABLE VERSION
The Mini-Modified division is designed to promote a
greater interest in Stock Car Racing at less expense than the NASCAR LMSC division. All
cars must be stock in every way except as modifications allowed by these rules. The word
STOCK means as it came from the factory for the particular model and year for
a car. This includes replacement parts by part number. Any reference to NASCAR LMSC rule
or section within these rules refers to the 2012 NASCAR Rule Book. These rules are subject
to amendment at any time when notice has been given. Notice shall be deemed effective
within two (2) weeks of the rule amendment and posting of the rule change by Old Dominion
Speedway.
If unclear on any of these rules, contact an ODS tech
official for clarification before making a change or spending money on parts or services.
Starting inversions for the Mini-Modified division will
be based on the average number of points earned by qualified entries over the previous
three (3) races. The winner of the last race will start in sixth position. The top
qualifiers will then be inverted for the remaining positions with the entry with the
highest average in fifth position, the next highest in fourth, and so on. If a qualifier
missed one of the three previous events, the inversion calculation will assume win points
for that event.
