Yes, you need 18" size wheels and the standard 18" BMW wheels for M135i fit perfectly together with the M Performace Brake option.

I can vouch for you and say the stock 18" M wheels (non M135i, style M386) also fit over M-Performance brakes. Albeit without much clearance

Somebody could confirm, please?

I asked at the dealer and told me they are incompatible because retrofitting didn't appear on their ETK system...

BMW offers the brakes as an option on all models, so retrofitting should't be an issue?!

Ok thx. Normally taking delivery during the next weeks. I ordered the performance wheels and keep the standard items for the winter. So now I'm sure they will fit over the also ordered performance brakes.

Confirmed yes.

The reason rear discs are add ons is that these differ between F2x and f3x

6797598 is for f2x
6797600 is for f3x.

It's to do with the handbrake internal hub being a smaller dia for F2x than for f3x.

Is it serious?

I am f20 120d owner, too

Yes.

I have been sent 6797600 parts by mistake, instead of 6979598, and the handbrake doesn't work even though I adjusted it as much as possible.Waiting 598 parts to show up to complete my install.
