Im getting new AST 5100 coilovers with swift springs for my e90 335i. Im debating taking advantage of a friends shop and just installing them myself over spending $400 on installation.
I was hoping to get an idea of exactly how difficult it would be to instal new coilovers including installing new front strut mounts and an m3 camber link kit.

I starting installing my Eibach coilovers last night. It's really not that hard, just a little tideous. It took me a couple hours for the front driver wheel, but that was mainly because I had a couple snags with have to re-position the spings compressors and trying to break a nut loose. Check the DYI on here for installing lowering springs. The only extra step is you have to remove the dampener as well, but that easy. My only tip would be to just barely loosen the nut on top of the shock/spring before you pull the assembly down. That way once you compress the springs, it won't just spin the shock.

Is there any specific tools that im going to need to complete the switch that I wouldn't have in my decently stocked tool shed? (other than spring decompressor)

Thanks for your post and help Sauer

An electric impact wrench would help greatly, especially for tightening the top nut on the front struts.

A good friend of mine helped me out with my install and honestly, I would not do it again. Although we did it in a hot garage in the middle of summer without any beers.

Good luck!

I didn't have any special tools at all. I did buy some good spring compressors on Amazon for less than $30. Take your time and make note of how all the wires are running before you go unhooking them. You don't want anything getting pulled when you turn the wheel. An impact wrench would sure make tightening the spring compressors a hell of a lot quicker, but I didn't have one.

Strong this.

Also, make sure you note the orientation of the headlight leveling sensor. If it's reinstalled incorrectly, your headlights will aim way too low.

Just finished my coilover install. Everyone will have their own little snag when it comes to suspension install. Mine was removing the stock front passenger strut. It was such a bitch prying that thing out. Good luck to ya! FYI , I used this is a general guide: http://vorshlag.smugmug.com/Instructions/E90E82-AST-strut-shock/4024296_g28pqx

From all of the reading I've done, it seems like the consensus is you're better off getting it done professionally if you don't have some experience and tools (impact gun).
