Hey gang,
Questions about this come up all the time & now, thanks to Michael Wolterman, we have the raw data.
The height can change based on vehicle weight, options & optional tire sizes. This data does not list every possible scenario, but it will get you close, make sure you note all the data for your make & model. Pay attention to the handwritten notes also, somewhere along the way someone clarified some of the data like the "showroom weight".
