Classes are split by engine capacity for any Two Wheel Drive (2WD) vehicle, whether Front Wheel Drive (FWD) or Rear Wheel Drive (RWD). Four Wheel Drive (4WD) vehicles have a separate class as they have a traction advantage with all four wheels putting down the power.
Vehicles may be registered, or unregistered. See the How to Start page for some conditions.
Ipswich also runs a separate ladies' class designed for the not too serious femmes, and there are two dedicted Junior classes for the young to have some fun in a controlled environment.
(Vehicles below are just examples, you could be easily be driving something unlisted!)
A Class – up to 1600cc
Many late model FWD cars, including Civics, Excels, Lasers/323s and Corollas, as well as some older RWD cars like Datsun 1600s (with the 1600 motor), early Celicas and Corollas, some Escorts and early and late Galants/Lancers.
B Class – 1601–2000cc
A mix of FWD cars like Honda Integras, some Lasers/323s and Corollas, and RWD models like Beetles, Datsuns, Escorts, Celicas, Galants/Lancers, MX5s, Eunos 30X and even Mazda RX series cars with the 10A motor.
C Class – 2001–3000cc
A good mix of cars including some six cylinder RWD Commodores, Skylines, 240/260/280Z Datsuns, rotaries with the 12A or 13B motor, FWD Camries and some VWs. Plus the occasional Porsche...
D Class – 3001cc and Above
A mix of RWD Commodores (including V6 and V8s), Falcons, big V6 Magnas, Starion Turbos (or any turbo car with an engine capacity above 1760cc), Soarers, 180/200SXs and Silvias, Supras and even Cobra kit cars...
Includes both normally aspirated and turbo cars. A mix of Subarus, Evo Lancers, Mazda Familias, Skyline GTRs and occasionally the odd Land Cruiser or Patrol. Class E will also include cars that can't be classified elsewhere, such as super lightweight baja buggies...
If you are unsure of the capacity of your vehicle, look under the bonnet for the compliance plate which lists what type of vehicle etc, including (normally) engine capacity. If your car is a 2WD Turbo (or Supercharged), simply multiply the capacity by 1.7.
eg A Nissan 200SX is a 2000cc (2 litre) engine, multiply by 1.7 = 3400cc ,which places it in D Class.
Rotary engines have their capacity multiplied by 1.8.
10a (R100, RX3) (just under 1000cc [982cc]) x 1.8 = 1767cc, which is in B class,
12a (RX2, early RX7)(1146cc) x 1.8 = 2062cc, and,
13B (RX4, RX5, late RX7)(1308cc) x 1.8 = 2354cc which are both C Class.
A turbo or supercharged rotary has the above CC's multiplied by the 1.7 factor again,
10a x 1.8 = 1767 x 1.7 = 3004cc,
so all blown rotaries are in D Class, regardless of which variety.
The club runs a Club Championship, Autocross Championship and Sprint Championship as well as class awards for Autocross and Sprints.
The overall Club Champion is derived from all points accumulated at any CAMS event, in competition with other club members.
Points are awarded 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 1, 1 etc. (Provided there are three or more club members in the class) If only 2 or 1 then the points are 9, 8 or 9.
If you compete at an event where you are the only IWMAC member in a class you would receive 9 points. If you placed 15th in class at an IWMAC event you would receive 1 point.
The Club Captain collates the points and keeps the tally. The Club Captain will score any event that they know about, so if you compete somewhere, please email them with a results sheet or other information on the event and the score will be added.
Members generally score most of their points at our events, however competing at many events, and disciplines, will keep the scoreboard ticking over. Traditionally the Club Champion competes at a variety of CAMS sanctioned events in many locations.
Autocross, Dirt Sprints, Rally, Hillclimbs, Gatton/Pittsworth Sprints, Short Circuit Events, Motorkhanas and Khanacross are all events that our members competed at last year.
For Autocross and Dirt Sprints the points are accumulated in the events at our track.
In 2018 there are 5 events of each type, so a maximum of 50 points over the year.
The Autocross and Dirt Sprint Champs are the highest point scores from any/all classes, so if a person wins in multiple classes, they may be the Sprint, or Autocross, Champ, but not be a class champ :)
