Bill Stein? Who's that? :-)
This is an opinionated reply based on numerous autocross and street cars. so _Imho:
No doubt about it, if you put Bilstein shocks in the rear on a BMW, your chance considerable increases of punching through the rear shock tower on the older models, or at least prematurely busting the rear shock mount on the later models. You also get to have it their way, pretty much, as far as the valving.
The one shock to go with on a BMW if you're serious about your car's ride quality, are not going to carry several custom valved sets for particular track applications, and also as a selling point to possible future buyer, is:
Koni
_Koni
____Koni.
The low pressure design does not put the extra load that the high pressure Bilstein and to a lesser degree Boge places on the upper mounting points. The easy adjustability allows changing settings if you go to an autocross or track event.
The reputation Koni acquired back in the eighties for quality control problems was deserved. Now if you blow a Koni, its likely you set them way too firm for the spring rates.
Btw I've found many newcomers to Koni tend to set them too firm. The idea is to match your shocks to the spring rates. Shocks can not make a car stiffer, a misadjusted shock or strut can only make a car ride either jouncier of bouncier. When a shock is properly matched to a spring rate and driving style, ie street, autocross, or track, that is when the ride feels nice and controlled and the component of the car's handling due to shocks and struts will be maximized.
YMMV,
