Hornet Car Rules

2018 Rule Amendment

Current Rule

5. Both classes to have a minimum ride height of 6.5” measured from all areas of vehicle except exhaust.

Analysis

All measurements of vehicles were measured from the left front (driver’s side) jacking/lift point to the ground. This can be considered the lowest structural point of the car for the purpose of this analysis. Measurements were taken without the driver inside.

‘A’ Class

  • The overall diameter of a 14” American Racer tire is 23 ¼”. The overall diameter of a 15” American Racer tire is 24 ½”. The radius is what affects the ride height. The difference in radius between the two tires is roughly ¾”.
  • Two vehicles were measured running 14” American Racer tires. These two vehicles measured under 5 ¼”.
  • Seven vehicles were measured running 15” American Racer tires. Of these seven vehicles, two measured at/or below 4 ½“, three more measured below 5 ½“, one more measured below

6 ½”, and only one measured at 7”.

  • Measurements were taken for two vehicles with and without the driver inside the car. The average change in height for these two cars was 0.5”.

‘B’ Class

  • One brand new vehicle this year was measured, and has confirmed that the suspension is stock and unaltered. This vehicle was a 1996-2000 Honda Civic, 2 door with trunk using 185/65/R14 tires. These tires will typically be the largest diameter within the class as vehicles are allowed down to 60 series which will reduce the ride height.
    The measurement on this vehicle was 6 ¼”.

Justification

  • The current rule, as is, requires an amendment/update with the addition of utilizing the driver inside the car (which will lower the ride height rule in itself). There needs to be a standardized method of measuring ride-height that is attainable on an average night of teching. Measuring “all areas except the exhaust” is not feasible with time constraints throughout the night. I believe the current rule of 6.5” is unattainable in its current state, and requires three different rules. One for ‘B’ Class, one for 14” American Racers, and one for 15” American Racers.

New Rule:

Ride Height

  • Ride height is to be measured from the left front (driver’s) side jacking point (pinch-weld) with the driver inside the car. This pinch-weld must be stock, unaltered, and non-tampered with.
  • All four pinch-weld jacking points must be within 1” (one inch) difference. This difference is to give margin for different driver sizes and the potential for different suspension stiffness.
    • ‘B’ Class ride height to be measured at a minimum of 5 ½” with the driver inside the car.
    • ‘A’ Class using 14” American Racer tires to be measured at a minimum of 5” with the driver inside the car.
    • ‘A’ Class using 15” American Racer tires to be measured at a minimum of 5 ¾” with the driver inside the car.

Example: If your car is measured to be 5 ½” in the ‘B’ Class at your left front, the three other points of your car may not be above 6 ½”. This is to prevent the staggering of suspension height.

All vehicles are to comply with this rule as of 16 JUNE 2018

 

2018 Changes: See rule #11

2017 Rules: Hornet Cars will be divided into two classes, known as A and B division. 4 cylinder car with a maximum wheel base of 105.5″ No rotary engine cars, no 4-cylinder Ford Fairmont’s, no Turbos, no All Wheel Drives Allowed. Complete stock Steel body, interior, frame and suspension. NO bracing anywhere except inside the drivers compartment.

“A” division will consist of cars with 134 horse power and more, to a maximum of 155 rated horsepower. Any Integras will automatically be in the A division.

“B” division will be consist of cars with an advertised horse power rating from the manufacturer of 133 horse power or less. Honda Accords will be allowed in the B division, but must use 14 inch steel rims.

Tire Rule for the “A” Division: All cars must run the American Racer that will be available  at Fountain Tire in Campbell River.  Call Brad,  250-287-9291 \ Maximum 6 tires per car per season, all tires must be the same size. NO EXCEPTIONS.

tire-information

A Division: can use 15 inch rims, Steel or Aluminum, Maximum 6 inches wide with a Maximum offset of 1” inch. Wheel Spacers are not Allowed. Maximum 2 inches of Camber per Wheel Allowed.

Once a driver has won the entry level Hornet B Championship or any Championship in other classes they cannot compete in the B Division.

Competition Rule

Any `A` division car with a lap time lower than TBA sec will be deemed illegal and disqualified from the race in which the time was achieved.

Any `B` division car with a lap time lower than 19.05sec will be deemed illegal and disqualified from the race in which the time was achieved.
