135i
F: 215/40R18 diameter = 24.8"
R: 245/35R18 diameter = 25.0"

M3
F: 245/35ZR19 diameter = 25.8"
R: 265/35ZR19 diameter = 26.3"

So the 1M tire diameter, assuming it uses the the same tires as the M3, is 1" larger than the 135i tire diameter.

The increase in radius coincidentally (?) matches the difference in height. Of course not all things are equal (suspension different, wheel width has small affect on tire diameter, etc).

Anyway, I will eventually consider lowering the 1M a little if some good prings are offered and there is enough clearance.
The model specs of the two cars ( 135 and 1M ) show the 1M is 1/2 " taller? I do agree that the preproduction cars I saw looked like a slight drop in ride height would make it go from "badass" to "SICK".
