Nice! Setup a post when you do the install. It would cool to see pictures of it in the process! I know it's a tedious task.
What are you doing for bushings. Rear subframe ? Are you going full solid aluminum or urethane, or just inserts ?
xdrive m235s have way more limited track coilover options, no KW CS for us.. just KW v3. Bilstein Clubsports are an option (48-238946) or MCS 2W's. I'm totally eyeing a set of those MCS 2-ways for next year
The reservoirs on their standard 2WNR's extend past the length of the normal strut, and into where the front-half shafts go into the wheels so I'm forced into remote reservoirs.
