Idk if you found anyone with the comp brakes but i have front ccb calipers from a m2cs just sitting. Been wanting to try and retro fit them to my f30

[@XandrMotorsports]

Of course once I think about whether or not I need (or want) upgraded braking Kevin comes out and post this to fortify that desire.

[@JCod306]

We need a video of that rear wheel process Fam! ✊🏽💯

[@idhammunirmohd1029]

A timely innovation. Also, there are floating 380mm rotors for the M which are much lighter than even the 1 pc 370mm rotor.

[@414Automotive]

The OEM 370mm rotors are actually technically 2-piece with an aluminum hat riveted on. I think they weigh about 29 pounds. How much do the floating 380mm rotors weigh?

[@TrackandBuild]

Great work! This is much simpler and cost efficient than BBK or buying F8X calipers. My only question is the strength of the bracket since it will take a lot of load. Have you already run this on the track without an issue?

[@kern417]

I have not and don't plan on it but i can keep an ear out for feedback from others who do

[@sr20dett1000]

They should make one for 360mm rotors from e90 M3. It's the same thickness.

[@Joshua-xv1vb]

For anyone with 19 inch 403m wheels the kit does run a little bit but on the tops of the caliper, however it will eventually stop rubbing.

[@DECKEDM]

Wont fit dude... are you really that simple to think a bracket made for a 340 caliper to 380 disc, and the other bolts and bushings to fit the 370 to 380mm disc , will work on a completely different 6 pot caliper .... . youll be needing a custom bracket.. so hate to burst your bubble... but it doesnt work like that buddy!!!!!

[@kern417]

@@DECKEDM i know you're really struggling with this so I'll try to break it down for you. F3x 370mm and F3x 340mm calipers both bolt to the same hubs. The caliper spacing itself is what determines the rotor size. F8x 400mm and F8x 380mm calipers both bolt to the same hubs. The caliper spacing itself is what determines the rotor size. F3x 370mm calipers and F8x 380mm calipers are the exact same caliper. 🤯

[@richardtrow2751]

Very nice 👌

[@NickthaGeek]

Hmm. Really concerned about the lack of material on the bracket. Only a tiny bit of metal between them two bolt holes. Surely would of been better to have the caliper slightly rotated clockwise or anti clockwise to get a bit more metal the bolt holes.

[@ebigford34]

Hi Kern, now that it has been a while, how are these holding up? They look awesome and I am very interested. I would just need to source some 2 piston rear calipers. Did you need to code in any brake changes? Thanks

[@kern417]

they work great. no coding is necessary in my experience.

[@la.m240i6]

You can code the S2NH or SPBR option. It calibrates the car for the bigger rotor.

[@kern417]

I've heard of people doing this but it's a hydraulic system so coding doesn't make sense to me.

[@NickthaGeek]

​@kern417 surely its more to do with the car stabilisation and abs than the physical size. ...

[@kern417]

Not sure what you're implying. Like I said I've been driving the setup for years with no issues.

[@techbsg]

So how do you align the bushings .. is there like a template or something or does it have markings?

[@kern417]

If it's the 370 to 380 kit, just align it so the hole is at the bottom like the picture shows

[@AH-007-75]

Can I use this bracket to add the 370mm front rotars from the none m3? The original bigger caliper says 370/380mm Can you shed some light Do they fit both m3 380mm like in the video , also the 370mm because the bracket must make the caliper same mm 370/380 fitting ????

Might have missed it. What’s the reason for needing to swap out the threaded bushes for the 340-380mm kit? both bushes look the same? I understand it on the 370-380mm

[@kern417]

Just because the hardware is the same across kits/platforms

[@acsmotorsportuk]

@@kern417 thanks for the reply mate, so it’s to do with the threads in the bushes? Like a different pitch? Was bugging me I had to know haha. Some kits don’t supply the bushes just the brackets.

[@kern417]

The hardware has a different thread pitch but it's used for both types of adapters, so that's why you need to replace the bushing even if you're not installing an eccentric bushing so it can fit the same bolt

[@olivtonyao]

Where did u get the brackets for the front

[@grocerylist]

Would you have an estimate in the weight difference Front & Rear for the 340/345mm aluminum top hat rotors vs the M3 380/370mm rotors?

[@katozord]

Realoem lists it as follows: 370x30mm fronts = 12.44 kg each 345x24mm fronts = 8.66 kg each 340x30mm fronts = 10.275 kg each 345x24mm rears = 8.66 kg each 380x30mm fronts (M3/M4) = 11.30 kg each 370x24mm rears (M3/M4) = 9.30 kg each. To sum up, the M3/M4 setup weighs 22.6 kg on the front axle (20.55kg on the 340mm) and 18.6 kg on the rear axle (17.32 kg on the 345mm). All in all the M3/M4 setup is 3.3kg heavier. I'd say it would result in negligible losses in acceleration compared to massive improvements in stopping repeatability on track. You're unlikely to utilize the bigger rotors on the street and you should rather spend the $ on more aggressive brake pads. Hope it helps.

[@grocerylist]

@@katozord Thanks for the very detailed info! I don't get to the track as much as I'd like to but improving braking capabilities would be nice. I could possibly consider doing it next time I need new rotors and going through FCP Euro for their Lifetime Replacement Warranty. Then after that, other than return shipping charges, rotors and pads would be free. Might be a little pricey shipping rotors back but cheaper than new rotors straight up. My only concern would be how this caliper hardware mod, which accommodates the larger rotors, would be for reliability and durability when pushed under track conditions.

[@bestiarara]

Would they work on 18” without removing the pads extensions? OEMs one got 4 pieces of steel that is said are there for ease of installation

[@kern417]

It's not needed. Pad removal is very easy without them. I was on the side of the track swapping pads between sessions and it took 30minutes.

Does the calliper actually fit properly with this adapter? I can see some rotor exposed in the “final thoughts” part, meaning the pads don’t fully cover it. Seems like the calliper is offset a little bit too far

That's how brake pads fit.

@@kern417at 4:31 you can see how the pad in the 340mm calliper goes right to the inner edge of the rotor ring. I also checked my m240i and it also covers the rotor completely. Yet you can see a bit of exposed rotor with the new setup. I’m not trying to diss you or anything, I’m just interested in getting this kit for myself so asking some questions that pop up in my head before purchasing it. Thanks
