Take a stick of 1 meter.
Place it in front of a front tire.
Raise the end of the stick till it touches the front of the car.
Measure the height in cm at the end of stick (or at 1 m length)
In the table, select the closest height just UNDER
your height and note the maximum angle for your car.
All products with an angle EQUAL or LOWER than your measurement will fit your car.

How to measure the angle of attack of your car
Example
You measure a height of 15 cm.
The closest height under 15 cm is 14,78 for an angle of 8,5°
