I didn't know that Bilstein had 2 different shocks for out cars. I would probably go with their street shocks. I bet the sport ones are really stiff. I don't know that for a fact though.
If your car is mostly a cruiser, I would say go with KYB gas adjust. I don't think there is a better shock for the price. If you want a softer ride, then get the KYB GR2.
