Excellent, thank you very much.

I'll be ordering this along with a set of "matching" front rotors (PN: 34116786392) and the rest of required parts for full brake service, thanks!

My Suggestion is to match the PN of the e9x hub of the same year as your 1 series.

The reason is that LCI e9x and even 2012 1 series had redesigned rear knuckles that robbed a few mm, logically the hubs should not change because e9x calipers don't chnage and neither do rotors. Just want you to be aware.

Refer to the ECS links. They make it easy and package it all nicely

Pressed in for bearing. Pressed in hub. But the hub has a nut to hold it in place as well. Refer to e46 rear bearings diy YouTube videos to see process and difficulty

The rear track from E90 LCI is 8mm wider than non LCI.
The Hubs from LCI ( BMW 33 41 6 783 671 ) are 8mm longer than pre LCI Hubs ?

If the part numbers are same for hubs, then maybe they widened up the chassis mount points for the multilink suspension? I would check the subframe part number as well for differences.

I think this is the rear knucle/kingpin that has the 4mm/side change

PreLCI
Wheel carrier, rear left 33326774807
Wheel carrier, rear right 33326774808


I dont know if the Hubs are 4mm longer - if they are that would require a new caliper and rotor position & dimention respectively, which as far as I recall stayed the same

EDIT:
It may be Subframe

I don't now. I think LCI is 16mm wider as non LCI.
So in part list it's all the same except for hubs and wheel carrier.
I think hub is 8mm longer and the wheel carrier has been set at the caliper mount to 8mm further.
My idea would be now the knuckle from non LCI and hubs from LCI to build in. So i can install the M-Performance Break on the rear in my LCI.

Searching the Hub part numbers can sometimes lead to dimensions and you at leas can get length/height.

I cannot confirm this. The closet I got was e90post members saying it is the rear Knuckle that makes it different, while keeping Rotor, Hub & Caliper centered correctly.

Just got my car back and I've definitely gained 10mm clearance on the outside of the wheel to the inner fender. Below were the parts I needed (actually I also needed another wheel bearing and a wheel carrier since my driver's side one got damaged when the shop was trying to press out the half axle..). If I had to do it again, I would just swap the whole subframe from a wrecked M3 instead of trying to do just the hubs.

Thanks again to Andrey for compiling all this information!

Rear hub swap parts:
2x E91 Performance Rotors (Dimpled and Slotted) - PN 34216795755
2x e9x Rear Hub PN: 33416760058**
2x Rear Wheel Bearing - PN 33416775842
2x Axle Nut - PN 33411133785

My "matching" front rotors:
2x BMWP Front Rotors (Drilled and Slotted) 34116786392
+ Brake pads of your choice

**Andrey mentioned this should be 33416783671 for the newer (LCI? 1ers)

That is unfortunate that the Carrier/knuckle was damaged, thats clearly makes the mod much more expensive. I can see why M3/1m subframe swap may be cheaper.

Did the shop explain why the damaged occurred and if its a common risk?

They had a tough time pressing the half axle out from the carrier -- to the point where the frame on their 20-ton press started to bend. They said they thought it was at that point that the carrier got damaged. We were pretty surprised it was so hard to press it out since the car only had ~90k miles on it and the car has always lived in California (not much opportunity for rust).

FYI, I couldn't find any slotted only rotors that fit when searching for my conversion. I swapped back to the stock hubs since then

+1 there are no slotted only rotors.
Refer to the first post fineprint for alternative rotors and whats needed for them

My mechanic did not complain about the bearings, he had issues with having to use a spacer or cutting anything to make it fit. That's how I ended up with smaller rotors and no E brake, but I'm still loving not rubbing.
