factory ride height specs M Roadster?

Does anybody know the factory ride height specs as well as how to measure for a 2000 M Roadster? I'm thinking of getting lowering springs, but I first want to see how close I am to stock ride height.

Thanks in advance,

Measuring my coupe I come up with numbers not even close to the BMW spec. I measured my car shortly after installing the Koni SA sport shocks in a parking lot at Newport. Right next to mine was a stock M coupe. I then measured again tonight.
Measure your car and compare to a couple of stock ones. The M coupe is supposedly lower than the M roadster.

Ron,

Are your measurements from the wheel lip or the ground? Also are you using the height measuring tool or the wheel arch? From the ground to the lower edge of the wheel arch, I have the following:

Front Left 25 10/16"
Front Right 25 13/16"
Rear Left 26 10/16"
Rear Right 26 10/16"

These measurements seem quite different from the Coupe. My 00' Roadster is 1" lower up front and 2+" higher in the rear.

Front Left 25 10/16" 26 2/16"

Rear Left 26 10/16" 26"
Rear Right 26 10/16" 26 1/16"

I'm using the lower wheel lip in all cases like mentioned above bulletin. For the front, I'm using the tool which only works on the front. I use the top of the wheel arch for the rears.
From the ground to the wheel arch Fenders) I come up with the measurements I added next to yours.

I remeasured the car like I did before. When I measured it the first time it had been jacked up, let down and moved back and forth in the garage. Took the car for a ride yesterday.
