They're sold separately because the 320/28i RWD cars had different hubs than the xdrive/335i cars. You have to get the appropriate rotor for your vehicle.

Does anyone know if the F80 Carbon Ceramic Big Brake Kit will fit an F30 or if the calipers would fit on M sport rotors for the F30???? Please help!

[zinner]

That has to be like 30k in brake parts ^^^ You are gonna mount them to a 320i ?

Creates a number of issues, not the least wheel clearance, cannot go below 19" wheelset. In addition, the CCB (1980s chopped tech) variety BMW puts on works very poorly in street applications, and well in hot racing applications. The true CCB solution is 370x30mm 3d strand woven CCBs (a 3 year tech now made by 4 manufacturers worldwide), not even Brembo has patents to it-yet. Can be customized (30-40 days), runs x2 x3 longer than old style CCBs (300,000 kms urban with recurring track days); runs -40F/C to +1500C, cold or wet, never contracts and does not oxidize carbon when hot since it is not resin based C Sci C. Posted a lengthier post:, F30 3d strand Carbon Ceramic.

Cheaper than MCCB and dust corrosion free. It will improve stopping distance vs M Perf kit, and save 15lbs per front rotor = 30 front =150lbs sprung weight reduction and corresponding improvement in handling.

Of course I would not put this on a 320i. But if doing so, 370mmx30 strand woven CCB is the way to go. If wishing to find out more, PM or check the other post.

Sooo read through the thread and still not certain.

So we know the calipers bolt up. But do the rotors 380mmm front and 370mm rear

Do you also need the f80 wheel hubs?

Rotors won't bolt up. You need the F80 hubs.

Carbon ceramic brakes for street use are not particularly helpful. It's a profit generator for BMW, both at the point of sale and later during service visits. There is nothing wrong with a profit motive of course.

Better investment would be a BBK with 6 pistons - front and 4 pistons - rear, either from Brembo or AP Racing.

I found someone selling a set of front and rear F80 M3 calipers for $600. Will they fit onto my F30 335i? My car has the M sport package but with the silver calipers.

Yep! This is what I did, and that's a great deal assuming the paint and the caliper seals are in good condition. They bolt straight on, you just need the proper sized rotors (370 front, 345 rear).

Nice! Any pictures of your setup?

I only have one of the front when I installed them back in August last year.

It's the same mperformance f3x setup. F8x just get them stock with larger rotors due to the f8x hub allowing the caliper to mount 5m farther away from the axle.

Can someone confirm if it is possible or I will need to fabricate some spacers that will be bolt on to wheel carrier - I am not even sure if this is going to work?

Blue M performance calipers are the same in both models (335i with 2NH option and M3/M4) but M3/M4 have slightly bigger rotors - 380mm vs 370mm (front) and 375mm vs 345mm (rear).

Absolutely yes it works, no spacers and have a video showing exactly what you need to do.

[itsrichierich]

So correct me if I'm wrong.

Non m-sport and m-sport use same front calipers but different real calipers. Non m-sport are silver while the m-sport are painted blue? Both setup use the smaller rotors?

M performance & M model cars use the same calipers and same rotors? But our F30 cars can't fit the rotors?

A little confused.

Its a better option to install the M5 front calipers and M2 400mm rotors. You can get the calipers off a wrecked car cheaper then buy the $250 frame/adaptor.

So yes and no and very very very easy to be confused. BMW did themselves no favors with the combinations of brakes.

Turner motorsports has a GREAT writeup on this btw, in far greater detail than I will go into here.

(but)

In general the "grey" front rotors are 4 pot and essentially the same as the colored (usually blue) m performance/sport brakes, which are ALSO identical to the F8X front default brakes. That said, they all have different rotor sizes. The grey have the smallest rotor, the m performance has larger and the F8X have slightly larger still (though not compatible with the F3X wheel hubs).

The rears CAN be significantly different, but also in general, the grey are single pot calipers and a smaller rotor. The "blue" (or red or orange) brakes are 2 pot and a larger caliper.

Its SUPER easy to get the default (non carbon ceramic) calipers off an F8X (wrecking yards are your friend) and then rehab the calipers and install the correct sized rotors on your F3X.

I have a full DIY of this posted up btw.

Again in general..

A little confused.

Bmw uses msport liberally. That's the source of confusion.

There are 2 versions of the front 4piston brembo.
Grey. They come on F3x N55 and B58 stock, msport or not.
Blue. This color is also labeled msport, but uses a 340mm front rotor only on the 4cyl F3x.
Blue for N55/B58 uses the same 370mm rotor as Mperformance brake packages for the F3x.

The same 4piston brembo also shows up in 370mm for F3x, or 380mm for F8x. This is possible because of different uprights on those vehicles. The calipers themselves can mount to either car without issues or mods. The stamp on the backside of the caliper will say 370/380.

The reason the exact same CALIPER design can be used on 340 or 370/380mm rotors is due to the one piece design. The mounting "ears" are part of the caliper. They are not removable. On most cars this bracket is an independent part on the caliper that can be swapped. This is not the case for BMW.

All of these 4piston Brembos, regardless of color (grey, blue, red, orange, yellow) use the exact same brake pad in size.

Are those a direct fit for our F30 or need some retrofitting?

Thanks, as you guys replied I found the Turner Motorsport write up:
https://www.turnermotorsport.com/t-b...ke-Differences

With all this being said, the M2/M235i should be the same calipers correct? I found a set of calipers that say "2015-2020 BMW M2 M3 M4 M235i" calipers but don't mention any part #s.

no.. double check all part numbers first. It is absolutely possible to fit F10 M5 FRONT calipers on the F3X with an adaptor, and use M2c 400mm front rotors.

[itsrichierich]

Ok, I will see if this guy can get part # from the seller. Here is what I am talking about: https://www.ebay.com/itm/2015-2020-B...0AAOSwhZ5fJNtc

[sqwinny]

^i hope whoever bought that set you linked realized that it only supports 340mm front rotors. Thus isn't M3/M4 calipers, but the 335i/340i M Sport front calipers. The listing is wrong.

The m235i comes with these so just wrong on the M3/m4 part.
