Well, I guess, TECHNICALLY SPEAKING you could mix "gas and automatic shocks" as EuroStyle has previously mentioned. For instance, I have two Bilstein Touring struts on order from bavauto (see my previous post in the E36 forum on this topic).
If you're light on the loot, just get two for the front and do the rears later.
Well, that's my opinions... I'm sure I'll get shit for it, lol...
