Arrow DIY: Aftermarket Spring Install

The process is very similar (with some simplifications) to regular 3 Series' install: http://www.e90post.com/forums/showthread.php?t=15397

All the bolts and nuts that need to be removed are circled in red. BMW recommends replacing all nuts and bolts.

Torque specs: http://www.m3post.com/forums/showthread.php?t=183005

I've done this so many times since when this thread was written. Now updated for 2010

Best Practices:

Front Axle:
1. When removing the front springs: use a jack and push up the front suspension to compress the spring, and then put on the spring compressor. This will save you a lot of time.
2. The strut piston rod can be pushed into the shock with hands.

Rear Axle:
1. When loosening the bolts: loosen the shock bolt first, the camber arm/wheel carrier bolt second.
2. When tightening the bolts: tighten the camber arm/wheel carrier bolt first, the shock bolt second.
3. It may be very tough to align the wheel carrier with the camber arm. Try jacking up the camber arm, and use a wrench as a level to position the parts.
4. When aligned correctly, you should be able to push the outer bolt completely through the camber arm, without any turning. This bolt is tightened by the nut.

So you removed and replace the spring without removing the entire front strut assembly?

Yup, as said, all bolts needed to be removed are circled.

SWEET! Any shots of the rear install? I know it's probably exactly the same as a normal 3 series.

How difficult was it using the spring compressor? I have done tons of coil-over installs before on my various cars including two e46 M3's, but have never installed drop springs. I recently ordered some H&R springs and plan on doing the install myself. Am a little worried about using the spring compressor in fear that it will slip or fail and the spring will shoot out and hurt someone, the car, or something else. Is it straight forward using the compressor and is it pretty sturdy? Would love some input on this. TIA.

They are extremely sturdy. They have little safety pins to push to keep the springs from popping out. It really easy and straight forward.
