Yeah in hindsight, I think the nicely modded e91 335i is going to be the way forward.

Doing the M3 subframes like djgandy said will probably be a route I'll look into.

Nicely modded 335i would be a lot less hassle!

Two more things. Get EDC suspension if you can / if it can be fitted. It sounds like you are going big on this build, and having the option of some comfort on the road is priceless.
The other thing, try and get a cross strut. Might need a bit of custom tweaking to get it over the N54, but it will really tighten up the front end which can be a bit wobbly on the e9x. Having driven a Z4MC with one and an e92 M3 without that is one thing I noticed. The front was ridiculously tight on the Z4.

The 1M actually may have one, so maybe that part will fit!

Here's the suspension set-up I found last night.

And a strut brace here:

Check the quality of the strut brace. It may be way better than mine but my one looks identical and cost me £60.

Ok. I also read somewhere that the M3 one fits the 335i because it goes down to the front bulkhead and joins there.
