So whats the consensus then?

Is it worth going with the M3 arms or mod stock ones?

What I get from the thread is that there is little gain in technical suspension performance going from OE to M3 bits in the back, unlike the pretty much universally agreed upon gains from the front OE to M3 bits mod. But there should be no harm.

Yup. The front stuff is worth it to go M3.

Things get a little more complicated in the back. In the rear the upper guide arm is worth it.

The upper camber arm doesn't really do much except reduce a few hundred grams (and obviously looks better). The trailing arm is the same already.

The toe arm bushings in the rear have a ton of compliance in them and should be replaced, however the M3 ones are NOT a bolt on replacement. Most people use Megan toe arm replacements in the back, there are also some sphericals as well like the bimmerworld or rouge engineering arms, if you are willing to go solid.

I am always tempted by the "make offer" option...

Is the lower camber arm completely incompatible between the M3 and non-M? It looks like the bushings are the same but the wheel carrier / hub are very different. The shock bolts in differently as well.

The camber arms are a direct swap, though you'll have to use different shocks. The TC Kline SA rear shocks I used are the same as listed for the E46 with the addition of some aluminum spacers for the lower bolt.

You will also need to make a bracket for the head light level sensor, if you have one, on the driver side.

Definitely shoot me details when you have a moment, might be the missing link for my rear end work.

Questions:

Stock nonM subframe? What toe arm did you use? Why the E46 damper instead of the 1M/M3 damper?

When you order the 1m SA rear shock, TC sends the E46 part with the spacers for the lower mounting point, so I am assuming it is the same for the 1m and E46.

KEY NOTE IN HIS PICTURE ABOVE: you see he could not use the upper powerflex bushing. This is the issue I had when I ordered the single action 1m rear shock. I could not get the nut to thread using the stock or Dinan bushings. Once TC confirmed the DA 1M shock had a longer threaded shaft, I swapped them out. A lot of wasted time trying to get the SA to work and I had to spend more money, but it worked out in the end because I love the DA rear shock.

I have stock subframe, m3 LCA, and am using the bimmerworld toe arm for a non M e82. The only piece that is custom I believe is the little headlight level sensor bracket that mounts to the LCA. HPA makes one, but it only comes with their LCA kit.

Yes, stock subframe. Stock toe arms work, too, though I have the Rogue bits. I didn't look into the 1M/M3 shaocks as I wanted the Konis, but I'm sure they're a drop in.

Sorry was referring to the E46 SA damper. Is it the same as the 1M SA?

The Misumi washers I used for the upper shock mounts came to $23.79 shipped. Not too bad. I couldn't justify an extra $500 for the DAs as I was only going for a "fast road" build.

The Misumi washers are a Shore 90, ether based polyurethane. Currently $8.19 each and ship in 7 days.

Fantastic. Thank you for working out how to install the shorter shaft Mtype SA damper.

Looks like HPA sells the level sensor bracket a-la-carte now for ~$50. Is there any reason to buy their lower camber link kit? The OE 1M/M3 link is cheaper.

Think the Misumi washer can be installed with the remaining pieces of the Dinan RSM?

As much as Iike HPA it was far less expensive to order from TheBMWPartStore.
