I decided to tackle the install using my friend's shop yesterday. Fortunately, he has a lift and a full set of tools, especially some specialty tools. Having done suspensions on E46 M3s and E39 M5s before, I figure I would have a pretty good idea of what to do and would be able to finish the job in a few hours.
Bad assumption. There were new obstacles that I hadn't encountered before, but luckily for me I had access to the TIS and was able to research the repair instructions as well as all tightening torques. In all, I probably spent 6 hours on the install. The first three were on the first corner alone!
Now that I have done the install, I think I can probably complete it in <4 hours, which seems to be the norm. I learned the tricks along the way to make life easier the second time around. It is always the longest the first time you tackle a job like this.
If you don't have the tools and a lift, I would not recommend the install. Based on my experience (suspensions, brakes, clutch/flywheel, engine swaps), I would rate this with a 5 difficulty on a 10 scale. Not tricky, but time consuming. It is also necessary to have the tightening torques, as some bolts are stretch bolts and require an additional process.
The one process that I did and is not done by most installers is to jack each corner up to the intended ride height and then
torque down the bushings. This way the bushings will not be preloaded when the car is lowered. You would be amazed at how much tension those bushings are capable of holding.
I also decided to use spacers: 12mm front and 10mm rear. They really push the OEM wheels out and fill the arches nicely.
Now onto what you've all been waiting for...... the pictures. Here are a few that I took today. The lighting wasn't the greatest, it was overcast and the sun was beginning to set. Enjoy!
