Well just for reference my front ride height on the non sport 545 are 14 5/8" drivers side and 14 3/8" passenger side.

 

This is not a stupid question. In fact it's the smartest question so far. We cannot assume that all this data is correct unless we first give complete instructions on how everyone should be measuring to begin with. Assume that you have non-technical people that don't even know how to measure and you ask them to do it you will have skewed results each time. Also, keep in mind about the units being measured. This is an international board and only in the U.S. do they use the so-called "standard" system while the rest of the world is on metric. Most knowledgable people are assuming that everyone is measuring in inches, so they too will give measurement in inches. However perhaps they're CONVERTING as well. Then think about the room for error on their chosen application. i remember in college i had the best calculator in the world and when graphing I'd come out to .999862 or somthing but my professor would get 1 and then mark me wrong. After 20 of these "wrong" answers I ended up with a 79.9% which she THEN would not round up to a B. So I got stuck with the C and that threw my GPA off....years later when I went to apply for law school, ............well hell you get the point.. LOL
