I know how to measyre the height of the fenders from the ground. Where do you measure the 100 - 160 mm ride heights measurements I read to?

 

FYI-

1) I first measured ground to fender-reasonable accuracy and easy.
2) Coilover instructions are to measure from center of wheel to fender-and once I thought about it this makes much more sense and probably more accurate than the first option (but more difficult)
3) Measure to the spec (bolt in front, frame location in back)-this provides a good relationship between the car and the road.

Just more info for consideration....
