They're not improper for use with stock springs, and in fact, are well-liked by most. It's more a product of BMW's shock tuning going from the best in the business, to straight to hell...likely the result of having to accommodate the runflats.

Got ya, you were referring to the hop from bottoming on the stops. Yes, with the factory compression damping and the reduced rear travel, the springs aren't stiff enough to adequately control compression reasonably into the stroke of the stops...but it should be getting into them none-the-less (not that the rear shocks aren't already overwhelmed with the new higher rates).

Uggg...let's not get started on that. We'd be here all night.
OK, I'm old and I need sleep.
Later man. And keep driving people what I imagine is bat-shit crazy out there at your track days. "FTW is that thing?!"
