Also, would it be prudent to get an M3 sway bar and bushings since I'm already under there doing the work? Or can I survive for the next 6 months without? I'm thinking I'd like to get the suspension on there, let it settle, align, and drive it for awhile before contemplating sway/bushings.
Cool set up. My .02 cents on your direction is for you to think about the part & installation expense. I've done what you are planning to do. Installing items piece by piece which cost more in the end than rather installing them in large groups ( don't need to do everything all at once).
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?
