Shock/Coilover options for M3 rear camber links on a E82

[JPuehl]

I'm going to swap the rear camber links/arms on my 135i which will require me to use an E9# M3 rear shock. I'm having a tough time finding a place that will either sell a mixed coil over setup, mixed being E83 fronts and E9# M3 rears, or just a Koni SA (yellow) shock or equivalent. I know this swap has been done before but I can't seem to find discussion about shock/coilover options. Any help will be appreciated.

An option. TC Kline rears. They appear to be TC Kline valved E46 rear shocks with the included appropriate spacers.

Running Ohlins TTX rears valved for E82 1M from 3DM.

Apex compiled a mixed set of JRZs for me. The front struts are all the same it's just whether they add a collar or not that makes them M or non-M. I think several other companies are like that as well. MCS also is for sure, I bought their collars when I went to M front knuckles.

M top hat is different (and far superior) too, for those who hate adjustable camber plates. Actually don't know if the M hats can be fit to nonM front dampers.

As I recall, the M strut shaft diameter is larger than 135i so strut hats will not fit.

This is true and from my searching the springs are also different diameters at the top where they meet the hat, so you need M struts and M springs for M hats, and non M struts and non M springs for series hats.

What you will be doing with your car will determine what is best for you. Koni SA and DA are good options, Ohlins(there will be a lead time of up to 10 weeks), MCS, and many others.

The TC Kline is the route I decided to go, will use them a couple years then consider a coil over setup.

Pretty much the boat I'm in now, prepping for Suspension V3.
