If you are thinking about M3 parts, If you decide to change the rear sway bar, the entire rear sub frame needs to be dropped. Depending who does the job, it's a 5-7 hour job @ +\- 100/hr for the install. If planning to track the car, then road balancing the wheels and tires maybe an option.
Also what is your main reason for changing the suspension?
Yikes. I may stay away from the M3 parts. It may also be overkill.
I have an xi so I hate the stance. Plus I find the suspension to be a bit floaty at times. I'm not that concerned with aesthetics, that's why I think the Eibach's will be perfect (considered H&R but I don't want that huge drop). I just want a more planted ride and a bit lower stance. I will never track the car, so it will just see road use.
