Handling Math

The Handing Math page this makes car handling math easy. Just enter 18 items of data and read the output data in the bottom of the form.

Cornering Force Calculator - Gs

The input items are self explanatory except for Center of Gravity height.

 

Find CG by hanging the car from it's nose or tail; when the car is hanging perfectly vertical, note the point where the car is hanging from, then set the car down and measure how high the point is from the ground in inches. That is the CG height. A sprint car is easy, other cars don't have the handy roll cage to hang them from, but you will figure something out.

The output items are listed below with explanation.

• Tire Loads at 1G - All data is for a car in the middle of the corner(not braking or accelerating) generating 1 G of cornering force.
• Front and Rear Tire Loads in ounces - they are what they are.
• Front and Rear Tire Loads in % change - this is the Roll Couple Distribution. These are the numbers to note; if you make large changes, try to duplicate these numbers to have the car work the same.
• Front and Rear Tire Loads - ounces per inch of tire width - these numbers should be the same, when the tires are correct for you car.

These number compare Front to Rear;

• Chassis Frequency in cycles per second(cps) - The front cps should be slightly higher then the rear. This condition makes the front a car be lighter longer (under-steer) for any given bump, else the car will tend to spin-out over bumps.
• Wheel Travel in inches - self explanatory.
• Chassis Roll in Degree - self explanatory.

Speed Calculators

There is a Gear Ratio Chart, Speed Calculators, Roll Out Gearing and Wheel Rate Calculator.
