Hey guys I have a spare set of F80 calipers, curious if anyone had any data on whether these can be made to work on the F10 535?

Yes but there is a problem with the rear, you will loose parking brake

Hey, thanks for the quick reply. With the front callipers is there an adaptor that I need to get? Curious if you had a link to a sale ad for them?

With the rear, I suspected losing the handbrake. Was there a kit I could look at as well that is compatible for the rear if I do the delete?

Front adapters will be hard to find, as you’ve got CCB calipers there with the +5mm larger caliper body when compared to the F10 M5 calipers that the caliper brackets will be designed for.

Yep direct fit. I just used a custom made 4mm thick stainless steel spacer/washer that fit between the caliper and knuckle, and longer bolts. The bolts I used were oem BMW subframe bolts, which were a bit long but I was able to shorten em. I had to order 25 of these spacers so if anyone wants I can sell them some.

My calipers were bought used on ebay, and I stripped them down completly ,rebuilt them with new seals and dust boots.

Hello, do you still happen to have any left over spacers after 6 years? lol just ordered some X5M calipers.

On ebay listed with the global shipping programme, so easy international shipping.

Putting the link here incase they are any good for someone to use as part of the brake upgrades discussed here!

In the case of the front calipers, no issues as they were used on my F31 - I’m running them with custom brackets and 400mm F87 M2 Comp discs and on the rear I am running F87 4 piston / 380mm rear set. Brake pedal feel is like stock and the performance is epic.

I’m interested in the rears! I just purchased some X5M 4 piston fronts for 395mm rotors for my 535 F10. Need the rears, would the M5 rears work with just rotors or would it require a bracket adapter?

M5 rear calipers require an adapter, which I'm not sure if you can obtain any longer. A forum member from Russia used to sell the adapters, but I think he stopped doing so. See this post for pics of install: https://f10.5post.com/forums/showthread.php?t=1220017.

As M5 calipers are effectively the same as the 550i (i.e. single piston, floating), there's no real reason to spend all the money on this IMO. Moreover, if you did the X5M calipers in the fronts and M5 calipers in the rear, your rotors are going to look VERY different. You can get cross drilled rotors for the front (from Zimmerman), but on the M5 rears the hat profile and design is different than anything you can obtain for the front. Given there is no performance benefit, a signficant cosmetic difference, and a high cost delta with M5 calipers/rotors in the rear, I don't see any reason to go that path. I'd stick with 550i calipers on the rear.

Regarding your question on spacers for your front X5M calipers, I did a write up on my own install here: https://f10.5post.com/forums/showthread.php?t=1792113. I show some pics of the spacer that I used, which is literally just a large washer. I was concerned about this spacer at first, but you should be able to to online to a hardware supply store and find a large washer that will work. Just make sure it is exactly 4mm in thickness (and obviously has a hole with a large enough diameter for the caliper mounting bolt to fit through).

F10 M5 calipers and brackets are a direct bolt on if using the 370mm F01 750/760 rear rotors. Several have done this, myself included, check earlier in this thread for more info if interested.

I haven't been following this thread overly closely, so didn't appreciate we'd found a way to use M5 rear calipers without a bracket. As they're still a floating single piston set up, the only real benefit to M5 calipers is to get a slightly larger rotor, correct?

If you have to use an F01 rear rotor for this, then I don't think a cross drilled option is available, at least no one made one when I did my brake conversion. I really wanted cross drilled front and rears, so that meant a 550i rear caliper was my best option.

What Pads fit the 750760 rotors with M5 calipers/Brackets? will 750/760 pads work?

Copied from your PM response for others to see:

F10 M5 non-ceramic or F10 550 pads will work. The calipers are the same (brackets are the only functional difference) and their respective rotors are the same thickness and swept area as the F01 750/760 rotors.

Correct. I believe the carbon rear M5 setup is different and requires an adapter bracket.

I did an analysis of all the known OE brake upgrades compared to the original equipment F10 braking systems, for overall braking force and front/rear bias. Posted earlier in this thread.

I chose to go with the G30 4 piston/F01 760 374mm front and F10 M5/F01 750/760 370mm rear setup as it gave the closest match of F/R brake bias to the steel M5 brakes, which I assume is as much rear-bias as BMW was comfortable putting into the F10 chassis. My calculations assume the same coefficient of friction used for both front and rear brake pads, which I realize is a BIG assumption, but that data is unknown so we can only use what we have.

I finally got around to upgrading the rear calipers and brakes on my F10 535dx, to complete the full F01 750i front & rear brake conversion.

F01 750i Front Calipers
374mm Zimmerman Rotors
Akebono Brake Pads
Stainless Braided Lines

F10 550i Rear Calipers w/M5 Carriers
370mm Zimmerman Rotors
Akebono Brake Pads
Motul RBF600 Dot 4 Brake Fluid

Fills up my Volk Bronze 21inch OEM BMW Style 128 really nice! Next thing to do is to powder coat the calipers.

The color mismatch on the rears made my eye twitch lmao.

Great job!

This thread is super helpful. Just picked up a 15 F10 550i and definitely want to upgrade the calipers / brake lines.

Found someone local to get G30 front calipers and a set of M5 rear calipers, will get the 760li 370mm front and rear Zimmermann rotors and run some ceramic pads (he has the oem brembo ceramics hah).

Question is what wheel spacer I'll need for the front given the prior owner (fellow forum member) put on 5mm spacers with 343m wheels. Has anyone run this setup? Appreciate Unspec suggesting 7.5mm but would like to confirm before starting to order everything.

Also anything sound off at all? Thanks as always.

[Blue Angel]

Have a look earlier in the thread to see clearance of the G30 calipers. Both myself and Unspec did it. He has 343M and I have 408M which are both M5 wheels with (assuming) similar spoke profiles.

My 408M will clear without spacers after machining the calipers, but I can’t confirm for the 343M.

343M are already a good fit without spacers IMO. Spacers may cause poke depending on your tire choice.

Thanks yeah I saw 7.5mm for the 343m w hub extenders. The 550i needs a 5mm spacers for the stock caliper but I don't think I'll be lucky enough to reuse. I'm thinking likely the turner 7.5mm ones might be the best choice to run with here since the 10mm ones with hub extensions are definitely going to poke.

Hi Guys,

I just got my calipers back and powdercoat guy documented the process for his Youtube Channel. Check it out! E70 X5M Fronts, M5 Rears. Prismatic Powder Heavy Silver Base, Peeka Blue topcoat, finished with clear. Logos are powdercoated!

https://www.youtube.com/watch?v=gmNlAJ_m70k

I sent all calipers to him disassembled and kept the pistons with me. I just got them back in the mail and started putting them back together today with a rebuild kit for seals and dust boots. I didn't notice when I took them apart, but one of my caliper pistons has a ding in it the size of a ballpoint pen tip like it was struck with a piece of metal after disassembly or while i was taking them out. It had a sharp edge you could feel by finger and it wouldn't go back in the caliper. I touched it with a rotary tool and it took the edge off, but there is a pit beneath the surface. It's tiny but I don't want to risk it not sealing. The spot is slightly smaller than the width of the inner seal.

I can't for the life of me find a replacement piston online!! Can someone help point me in the right direction for a Brembo M4.42 caliper 42mm replacement piston? It is from a 2012 X70 X5M. TIA!

Wow, that guy does solid work. The guy I went to I cannot recommend at all - every caliper was undercured and has resulted in spiderwebbing in the clear. The fact that the brembo logos are powdered into the caliper is perfection. Wish I sent mine off to him instead. Oh well.

So I was painting a set of G11 calipers and one of them fell off the hanger crushing the crossover tube. Of course BMW doesn't sell this line separately... Anyone have any ideas on where to source this?

I am usually all for buying tools but I would rather not buy a tubing bender and flaring kit that I will likely only use once or twice.

Sorry to be the bearer of bad news, however there is no off the shelf soloution for this.

As you have found, BMW do not sell the line as a consumable part. This is frankly idiotic when other OEM’s such as Porsche make their hard lines orderable as separate parts from the calipers.

Your only option is to have one made up and hope that you can match the OEM contours so that it doesn’t like a mess!
