Western States Dwarf Car Association
2006 GENERAL RULEBOOK
With the nostalgic look of early stock
cars, Dwarf Cars are scaled copies of 1928 to 1948 vintage
American coupes, sedans and trucks. They are powered by a
motorcycle engine. The bodies are scaled down versions of full
size cars.
2006 WSDCA
UPDATED 1-06
The following are "COMMON SENSE" type
rules. Our objective is to minimize rule changes. Do not attempt
to build a Dwarf Car without first contacting a WSDCA Board
member for rule clarification. No exotic equipment, (meaning
unusual or out of the ordinary). If a car is built that does not
meet the Dwarf Car specifications, it will not be a Dwarf Car.
Interpretations of or amendment to these rules may be made at
anytime. The rules and/or regulations set forth herein are
designed to provide for the orderly conduct of racing events and
to establish minimum acceptable requirements for such events.
These rules shall govern the conditions of all events, and by
participating in these events, all licensees will be deemed to
have complied with these rules. No express or implied warranty
of safety shall result from publication of, or compliance with,
these rules and/or regulations. They are intended as a guide for
the conduct of the sport and are in no way a guarantee against
injury or death to participants.

All drivers will draw pill for starting
positions in heat races.
Cars will line up with lowest pill
drawn on the pole of heat 1, next lowest on pole of heat 2, etc.
After the pole positions of the heats are filled,
the ninth lowest pill lines up on outside pole of heat 1, 10th
lowest pill on outside pole of heat 2, etc. All positions will
be filled according to this alternating manner.

WSDCA Senior Division
The Senior division established for the 2005 racing season is
for driver 45 years of age or older. This division will have
their own points and all of the existing rules apply. Drivers
can not enter both divisions in the same National event and
points can not be transfered between divisions. (ie: If a driver
raced the senior division at Nationals #1, he could race the
regular division at Nationals #2, but he would have points in
each division, not a combination of points toward a
championship). The payout for Seniors will be based on the
percentage of the cars they have for that event. A senior
division will be run at all 4 WSDCA Nationals. A senior division
may be ran at Regional races that have been pre-approved
and advertised as a separate division prior to the event. There
must be a minimum of 10 senior cars competing in that event to
be eligible for separate points and payout.
WSDCA
Points:
Only Saturday night Main Event points
count.
300 points to the winner and then down
by 2.
( ie: winner =300, 2nd place
=298, 3rd place 296, etc.)
Regionals or home points counting
towards WSDCA points, will start at 150 points and go down by 1
for each position.
Cars who were present at the event will
be receive points as long as they took a green flag. This
includes DNF and DNS vehicles. They will receive equal points
behind the last place finisher in Saturday nights main event.
2005 Championship Points:
Your best 4 races will count towards
the championship. 3 of those races must be National events. You
can count a 4th National OR 2 Regional
finishes OR your home points + 1 regional to make 4 races
count.
Regional races will be scored with 150
points to win then down by 1 for each position. Home points with
your association or track will be counted the same way with 150
points to win the championship, then down by 1 for each
position.
In the event of a tie, the overall best
National finishes will decide the tie. Any driver that
participates in the 4th National (Marysville) will
receive an additional 50 bonus points.
WSDCA Recommended Association Points:
Heat winners: 20 points down by 2 for
each position
Main Event: 60 points down by 2 for
each position
Passing points: 1 per car passed from
original position to original finish.
Appearance points: 20 points but must
take a green flag ( ie: packing, hot laps,etc
B Main points will be awarded after the
last place finisher from the A main and go down by 2 for each
position.
These are common sense type rule
violations. They are designed to give Clubs an outline on how to
deal with violations and categories those violations may fall
under. We should keep in mind that it’s our goal as officials to
promote and encourage the growth of our sport and to increase
car count and not to use these violations as a method of
singling out or disqualifying drivers from an event. All cars
should be teched prior to any event and all tech should be
carried out by assigned personnel and should be between the
driver/owner of the car in question and the tech person. Any
tech issues not resolved should be brought up to the board of
directors for clarification.
