Sure, but we have a taller strut body and not nearly as much spring rate as the M3.

Tire size doesn't have much to do with it, besides some added compliance in the sidewall if you're taller (I'm 255/40-18)

That's good to know then. The difference in weight between the 35 and 28 isn't that much, so hopefully the shock and perhaps a bit of bumpstop trim will be enough to get me to a point of no bottoming out.

If you have an s drive, and 19 in wheels, I trust you live in an area with much better roads compared to some of us.
