I'm going to love this thread as I'm still getting used to terminology and such with these cars lol. will have lots of dumb questions!

anyway, did all 01 x5's come with airbag suspension? or did some have just regular springs/shock suspension? was doing the brakes on the back of my 01 last month and didnt see any airbags, just springs/shocks from what I could tell. I swear I thought I saw the airbag tank and such in the rear footwell but wont know for sure until I can find time to sneak out and move all the christmas presents I'm hiding under the cargo cover lol.

regardless if mine had airbag suspension and has since been retrofitted to springs...can I remove all the airbag components to free up some space/weight?
