Suspension shopping list

I'm replacing my suspension with Sport package springs and Bilstein B4s. The current plan is to pre-assemble the new struts. I'd appreciate it if you could go through the following list and let me know if I'm missing anything!

Also, any installation tips are welcomed. I have spring compressors and have worked with MacPherson suspension before but not on a BMW. From what I've seen so far, the hardest part appears to be removing the strut from the wheel well? I've also noted that washer #8 is installed with the black stripe facing up.

Thanks

Update: I ended up reusing many components as I saw no reason to replace them. The strut mounts, rear lower shock mounts and both front and rear bump stops were quite worn though. I've updated the lists below accordingly.

The hardest part will be compressing the front springs to install them on the struts...unless you have/access to a spring compressor, or pay a shop to do it.

Another option is to buy a kit that is already assembled for you...

I just replaced my shocks and struts on my '07 E90 335i.

When you remove the old struts, remove the brake caliper, and rotate the strut so that it points outward from the wheel well. You won't have enough room above it to remove it when it's pointed upright. In order to rotate it out, you may also have to compress the spring slightly when it is still inside the wheel well.

Make sure your spring compressor has clearance to clamp between the top strut mount and the spring plate (parts 9 and 1 on your diagram). The other end of the compressor can then go on one of the lower coils. If the top clamp is on a coil, you won't be able to compress the spring far enough to remove the tension on the strut (at least I couldn't with the sport suspension).

I would also highly recommend using one of the spreader tools to open up the strut mount on the steering knuckle. Your old struts will be dirty, and will make removal more difficult. I used a mallet to help loosen the strut in the mount (even when it was spread open with the tool).

Edit: Something I forgot. You probably also want to pick up the strut socket tool for the top nut. It has a cutout to get your allen/wrench in there to hold the strut shaft while you tighten it. The nut is down in a deep hole, so it's not really possible to get a wrench on it.
