Not sure if there is a large difference is between the US and the EU market.

They are not the same as the 750i, they are a extra upgrade for the 750i as a High speed brake system and standard on the 760i.
The callipers are slightly bigger and have larger brake pads.
Both rotors are 374X36 so there is also no difference.

I do have a set 760i callipers but I assume that shipping to the US would not be cheap.

Thanks! Really worked for them but the results are night and day.

I won't put the ///M decals since it is not an M5, even though it is really close to it.
Called it the baby M5, Sure sounds better than the M in my opinion lol.

I like the clean look so it stays that way

But it is a ///M brake caliper. I think a M badge is not out of place there!

I know this may sound like the least of the worries but are there any off the shelf 4mm spacer that we can buy to retrofit the x5m front setup? I have a brand new set of calipers and rotors with extended bolt and everything sitting in a box and I just haven't found (or dare I say spent enough time looking for) the 4mm spacers.

Wouldn't some big ol' washers fit the bill fine?

I would think the spacers/washers will need to be pretty precise to avoid abuse of the pads/calipers

Definitely, but they do come in pretty thin sizes as well, I'm sure you could mix and match and get the right thickness. If it's a tad too thick, nothing some sand paper and rubbing couldn't fix

If you have a friend with a 3D printer, you could ask them to print a solid piece of 4mm high density plastic.

Thats a good idea, there are actually more plastic 4mm spacers available off the shelf, so I might go that route. I think summer is when I put them on. Its funny, I have one caliper from an x5m in black, the other from a Rolls Royce, with their logo. Have to decide whether I repaint them Alpina blue or keep black

The only thing I'd be worried about with the plastic is that it might squish when the bolt is torqued to spec, so it might throw it out ever so slightly. Though it will definitely depend on the plastic material.

For rotors, the 2-piece (aluminum hat + steel friction disc) options are Genuine BMW, Pagid, Zimmermann Formula F, or Brembo. Does anyone know if these options: Pagid, Zimmermann, or Brembo have a better rust and corrosion preventive coating than BMW's?

It looks like Pagid and Zimmermann are fully coated, but how about BMW? On my current BMW rotors, the rotor edge and non-friction surfaces are rusting after 30k miles. Thinking about switching to Pagid or Zimmermann to prevent this if they are better. I haven't held both to see but curious if someone else had.

[Unspec]

Anyone have any suggestions for front calipers that don't use BMW's stupid clip system for the floating calipers? I'm not really looking for increased performance, I just despise the clips with every fiber of my being.

I'd opt for M5/X5m calipers but I run 18" for winter.

[addy27]

There's a trick to those clips..and it sucks specially if you have painted calipers.. basically you put both end in first and then use a screw driver and put the center up and push into the little divot....

There is another version that you could try out, in the US it only came with Rolls Royce..but its also the same setup that is used on the 760i security version and I am venturing to guess since they fit on the 760i security, that they would fit on F01 and hence on F10s.

These will allow you to install the biggest rotors 410x36mm

If you do go this route, you'll be boasting the biggest brake setup!!

Yea, it's specifically because I painted my calipers and then proceeded to ding them the fuck up. Those look great, but would they fit on stock rotors + 18" rims?

Hopefully this thread will be a nice source of information for others wishing to do the same and possibly help out with what fits and what doesn't.

So far from my online research and personal experience it seems that (7 Series ) F01 front brake calipers and rotors are a direct bolt on to our cars. Bigger caliper while still a single piston, uses a 374x36 Rotor. The stock F01 rear calipers do not fit as the F01 doesn't use the electronic brake on its caliper.

It seems that E60 stuff may fit on the front as well based on online research but not entirely sure as I have not tried it personally. E60 M5 calipers are cheap and 2 pistons with a 374x36 rotor as well.

G11 Brakes sadly did not fit. I was able to bolt them on my F10 and the front calipers themselves mount up to the carrier but will not work due several design changes of the cars. BMW went from 5x120 to 5x112 bolt pattern, therefore the brake pad of the G11 caliper interferes with the hub of the 5x120 rotor, it also was not centered on the rotor itself, but a washer or spacer could have fixed that. The rear G11 calipers did not fit at all.

I am in the process of fitting the front brakes from an E70 X5M/X6M. These brakes are massive and are a Brembo caliper with four pistons. The rotors are also massive at 395x36. So far the X5M caliper bolts on to the stock carrier without an adapter and everything appears to line up. Still waiting on new brake pads and rotors I ordered to fit everything up and test them.

I've attached some pictures. Blue calipers are G11 and Black ones are X5M.

18's no chance..
stock rotors..only Half of the brake pad will see the rotor surface so again a no.

Im very intrigued by them but I scored some X5m/RR Calipers in black brand new that I am thinking of putting on once my fronts wear out. Rears will be swapped for sure in the summer

I have Zimmerman rotors on my 530d. They are coated, but it does not prevent rust. I did not paint them ahead of installing on my car and you can see what happened after a few months on the car. I then took them off and painted them with high temp primer and paint, and I STILL have rust coming through again! I'm not sure what to tell you, but Zimmerman coating is not the answer.

Sorry about my delay in responding . . . I'm not getting email notifications on additions to this thread for some reason. This washer things was an issue for me too. Fortunately, the place I got my X5M calipers from were able to create a set of 4mm spacers for me that worked flawlessly. They're effectively just big washers, so you could go to a hardware store and search for some. Bring a digital caliper with you to check the thickness of the washers to ensure they're close to 4mm, but otherwise there's nothing special about them. However, I would not use a plastic one; I think they need to be metal. You could probably go to a metal fabrication place and see if they could make you a set as a worst case scenario. You can see the washer I have in the pic.

I did the 750i caliper and rotor upgrade and it fits my OEM M Parallels 18x9.5 et25 front with a 12mm spacer. I used these wheels as my winters.

Tight fit!

Here's a before and after shot...

How's the spoke clearance?

18x9.5 et25 front with 12mm spacer brings it to et13.

I could've used the front 18x8 et13, however it hits the low profile wheel weights by 2mm. I'm sure if I moved them around it would work, however the rear square set has bigger lips.

That's a pretty crazy aggressive offset, but is that primarily due to the design of the wheel? e.g. caused by how deep the spokes are set into the barrel.

I've also been wondering, for the folks who reported much better braking, how much of that is due to just having new brakes vs the bigger rotors.

Yes it is primarily due to the design of the wheel. Since I have switched over to stainless braided lines, 7series front calipers and 374mm rotors, I do notice better stopping power, especially on the highway where I notice it the most.

With summer 21in wheels on factory brakes, this 535dx was very hard to stop. I'm not sure how I am able to fit the BMW Style 128 due to the concave spoke design (21x9 et24 245/35, 21x10 et24 285/30) on with the new 7series brake setup.

They barely fit when I had the stock 535dx calipers. Like 1mm of clearance almost touching the face of the calipers. I may have to put a 3-5mm spacer and will be test fitting them sometime next week. Hopefully not too much poke as they are already aggressive offsets to begin with.

My stock rear brakes are almost done, so I have bought 550i rear calipers and rotors and will be upgrading the rear brakes too. The bigger rotors will fill up the inside gap very nicely.

Can't wait!

It kind of sounds like the improvement came from new hardware rather than upgraded hardware. e.g. you would have seen the same result if you got new rubber brake lines, new 348mm rotors, etc. 348 rotors never had a problem triggering ABS.
