Hi Guys; My car is a 1984 e23 728i. It is currently running a stock setup for suspension that has fallen badly from grace. Just imagine driving a bouncing castle ... Anyway I have been doing some research and I found that since I want to lower the car a lot, the bilstein b8 shocks would be good. I wouldn't mind a stiff ride that handles corners well but again not so stiff that I would feel as if the car was kicking me in the nuts. What I want to know is; would it be possible to achieve great lowering if I went for the b6 sport? In either case do I need to change my spring or I can stick with the stock one? Another thing is that I am planning to get 19" rims next month. Will they fit in well with the bilstein b8 or b6? which shocks will give a better lowering? If anyone has any helpful information please point me in the right direction as I am not so enlightened in this area. Feel free to offer me used shocks that are in good condition. Thanks 4 ur time.
