Full Classing Rules: 

Sport Class

For stock to mildly modified street legal lower performance cars with a 13:1 weight to horsepower ratio or worse from the factory and vehicles on the allowance list. Calculation is the factory listed curb weight in pounds of the vehicle divided by the factory listed horsepower. Calculated number must be 13 or higher, or the vehicle must be listed on the allowance list to be allowed. 

 

Engine:

The engine must remain stock, as from factory, with the exception to:

  • Air filter & intake upgrades up to the turbo inlet or throttle body/carburetor inlet. Whichever comes first.  

  • Exhaust upgrades up to the first flange off the header on naturally aspirated cars and the first flange off the down pipe on turbo cars. 

  • Engine tunes 

  • Common reliability mods or fixes that don't increase the horsepower of the engine are allowed. e.g. oil cooler & baffles, catch cans, upgraded radiators, motor mounts etc.

 

Drivetrain:

Drivetrain must remain stock as from the factory with the exception to:

  • Gearing ratios may be changed in the differentials only

  • Limited slips may be added

  • Upgraded shift linkages & parts may be used

 

Suspension & Brakes:

  • Any part that can be bolted or fitted into the factory mounting locations, without modification, may be used

 

Interior & Exterior:

Interior & exterior must remain as from factory with the exception to:

  • The driver & passenger seat may be replaced 

  • 4/5 point harness may be used 

  • Rear seat delete kit is allowed

  • Steering wheel may be replaced

  • Cosmetic parts & changes that don't require modification of factory parts are allowed

 

Wheels & Tires:

  • Any wheel may be used

  • Tires must have a rating of 200TW or higher

  • Tire width is limited to a maximum of 225 or +20mm over the widest O.E available size for that model's generation, including the optional factory installed packages and higher trim levels. **This excludes any trim version or added package that upgrades the model to a better than 13:1 ratio. (e.g. Widest O.E size is 235 = Max allowable width is 255)

Tuner Class

For stock or mildly modified mid range factory performance cars & modified enthusiast cars using the stock or a swapped in engine.

 

Engine:

Modification allowances are based on the weight to horsepower ratio of the vehicle using the factory listed curb weight of the vehicle divided by the factory rated horsepower of the engine that is currently in the car. Allowance list vehicles are considered 13:1 or worse.  

  • For engines with swapped blocks & heads, use the horsepower rating from whichever engine had the higher rating. E.G. K20A2 (200hp) head on a K20A3 (155 hp) - use the 200hp horsepower rating of the K20A2    

 

12.99:1 or better

Vehicles must use the O.E equipped engine or a swapped one of the same manufacturer with the following restrictions:

 

Turbo & Supercharged Cars

The engine must remain stock, as from factory, with the exception to:

  • Air filter & intake upgrades up to the turbo inlet or throttle body/carburetor inlet. Whichever comes first. 

  • Exhaust upgrades up to the first flange off the down pipe 

  • Engine tune 

  • Common reliability mods or fixes that don't increase the horsepower of the engine are allowed. e.g. oil cooler & baffles, catch cans, upgraded radiators, motor mounts etc.

 

Naturally Aspirated Cars

The engine must remain stock, as from factory, with the exception to:

  • Any externally bolted on part may be replaced & upgraded

  • Minor internal reliability mods that don't increase engine performance are allowed. e.g. Oil baffles & pumps, better head gasket etc.

  • Engine tune

  • Turbocharging & supercharging is not allowed 

 

13:1 or worse

Any engine (stock or swapped) and modification is allowed with the exception to:
