// Angle of Approach Calculator

Make sure you can sail right up your service ramps

Use the calculator below to determine your vehicle’s maximum angle of approach. Then shop for any Race Ramps with an angle equal to or less than your result.

To determine the best angle of approach for your vehicle, we have devised the “yardstick test” below. If you do not have a yardstick, carefully measure out 36″ with a tape measure or other straight, rigid object. You may need two sets of hands to get an accurate measurement here.

YARDSTICK TEST

1. Place a yardstick/tape measure at the base of your front wheel.

2. Raise up the yardstick or tape measure until it hits the underside of your car (the spoiler).

3. Measure vertically from the ground to the end of the yardstick or 36″ point on the tape measure. Record that height here (in inches).
