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...
E Class – AWD/4WD class, including both N/A 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...
Juniors are aged 14-17 and have two classes:
- Junior A (JA) class is for up to 2 Litre cars (normally aspirated only)
- Junior B (JB) class is for over 2 Litres (also normally aspirated only)
Note - as it is expected that Juniors are relatively inexperienced our club has an existing rule that Juniors are not allowed to run 4WD or turbo cars.
If you have a potential Junior driver but no car, contact the club for more information, and come for a come and try day, as the club will have a vehicle available for use.
FOR LIGHT HEARTED LADIES
Ladies (L) class is for female competitors who want a more relaxed competition, with no restrictions on the type of car. Any serious competitor are urged to mix it up in the classes described above.
CAPACITY MULTIPLIERS FOR TURBOS and ROTARIES
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.
