fun2drive, thanks for your input.

More info:
Looks like the folks in UK confirmed the shocks on the E90 330i are in fact Bilstein B4/Touring class shocks, but valved with BMW specs. So that would mean the aftermarket Bilstein touring class shocks would be excellent replacements with Bilstein's own valving specs (which may be good if you dont like BMW's spec) stiffening the ride a tad while extending shock life.

Tirerack offers the Bilstein part numbers for sport and non-sport suspensions.

FYI, here are the part numbers for non-sport setups cross referencing Bilstein's application guide:

22-135001 Shock Absorber
BILSTEIN - B4 Gas (Ersatzteil)
Fitting Position Front Axle Left; Suspension Strut; Gas Pressure; Twin-Tube; Top pin;

22-135018 Shock Absorber
BILSTEIN - B4 Gas (Ersatzteil)
Fitting Position Front Axle Right; Suspension Strut; Gas Pressure; Twin-Tube;

19-135021 Shock Absorber
BILSTEIN - B4 Gas (Ersatzteil)
Fitting Position Rear Axle; Gas Pressure; Twin-Tube; Top pin; Bottom Pin;

The misc parts that should be replaced with a shock/strut refresh comes to approx $250 from bavauto
