Gear ratio calculation tip

Summary:

Tech tip on how to calculate your gear ratio.

Details:

1. Jack up both rear wheels off the ground and chock the front tires (for safety).

2. Place your car in neutral and place a small dot on the aft end of the drive shaft.

3. Now place a dot on the tire as well. Have someone turn the tire one revolution while you are under the car watching the dot on the rear of the drive shaft. Count the number of turns it make and use the chart below to determine the gear ratio you have.

2-3/4 turns equals 2.73's
3 turns equals 3.08's
3-1/2 turns equals 3.55's
