It's honestly all over this thread:
- Eccentric bushings from @335d_cypis or @Turbid (both on this thread).
- Since I have a 328i, I needed a hub spacer and centering ring that @335d_cypis produced for me. Allowed me to run m-performance Dimpled/slotted rears (see page 89 where I detailed which brake discs you could get). This allows me to keep/use my parking brake without modification.
-You can reuse the brake sensors that came stock.
- You have to cut the stock dust shields and bend them out of way.
- I already had stainless steel braided lines from ECS.
- I coded sports brakes (+SPBR) for the 328i.
- I do have an M3 master cylinder but haven't installed yet. With a good pressure bleed it's really not that bad without the m3 MC but again I'm not a speed demon.

Spool st reet actually did a pretty good DIY on this one. https://*********************/threads/diy-f30-m-performance-brakes-on-e90-e92-e93-guide.2941/

Anyone know the piston diameter on stock sport/m-sport e90 front brake calipers?

What model? 57mm on both 328/335.
On performance brakes on 328/330 there are 6 pistons, not sure diameter of each.
Piston diameter is engraved on ATE pads.

do i buy the stainless brake lines for the F80 or the E90
since im using F80 caliper on E90 chassis

Still buy the e90 ones since it's the right length. The threading into the caliper is pretty universal. I have the ECS SS lines on mine.

Thats the kit right there:

I'm looking for a full set that can support me installing the F30 performance brake MOD on my 2014 E84 X1. Can you support this set-up?

I would like to give an shout out to 335d cypis. He has been very helpful in providing me the detailed, one on one information I needed to get this MOD going on my car.

I recommend buying the ECS or Turner exact fit lines. The stoptech and normal ECS ones don't really fit correctly IMO. They just use a washer instead of locking into the brackets like stock ones do. While it probably wouldn't happen nothing is really stopping them from turning and loosening in the brackets.

I returned the stoptech lines and got the ECS exact fit ones! It is only $20-30 more IIRC so I don't see the point of getting the ones that don't fit like stock.

The exact fit lines from ECS are nice. I would have preferred them to be black but that is a minor thing...

I've had Stoptech ss lines on my car for years now no issues, never heard of them not fitting before

The stock lines have a notch in them so they fit the brackets. They are held in by the spring clip so a round fitting with no notches on the front could turn and loosen.

The stoptech lines are round and just have a washer on one side because it uses a generic fitting. The spring clip doesn't really fully tighten so the line isn't as secure. I am sure it works but it just isn't as nice as the exact fit ones IMO.

My impressions so far of the 370/345 (e60 rotor) bbk

its a decent upgrade, main thing is fixed calipers. so before the rear pad would overheat 1st and cause crazy vibrations, so i tried just the rear 1st which added another 20% time before the front would cook and vibrate also. so with full bbk i never get any vibration under braking. m3 master is a must with full bbk otherwise it felt worst and had more travel than stock brakes.

its a donkey size caliper setup but pad surface area is small so pad quality will play a big part if tracking and because of its donkey design, it stick out a lot from the hub so verify wheel fitment.

370mm pad are actually less aggressive (they suck) than the 340mm but all rear pad compound is same as 370mm front compound from my research.

running srf and even still getting a little weeping at bleeder threads, next is TI shims, more brake ducting and better pads.

good value for full bbk BUT in hindsight would I have paid more to get more, Yeah

There are 3 different pad compounds:

1. Base for North American market. No dust, crappy feel.
2. S2NHA: Euro version. That is one you want. Aggressive feel. Dust comes complimentary.
3. P337: 370mm pad From my research, same compound as Base.

Since all pads are same shape and size, S2NHA is a must for performance upgrades.

Is there a clear reason no one has retro-fitted the complete F3x rear corner? I don't see an issue, unless spline count is different...and a good deal of labor. This is the way I'm going on my 135i, after previously mounting the E9x rear hub mod, in order to get some tires and wheels worth a d*%n.
