For the fun of it of course. This is for my M coupe and not an e90 btw. blasphemy I know, but looks are a big deciding factor as I'm sure as hell not going to track the thing.

Hmmm yea I see that. But I'm quite sure my rears were smaller before I got the 335 on front and rear.

Probably, optical illusion due to different wheels or body-style perhaps.

Nope, I actually think I got 2 different type approvals from the Danish MOT stating the difference.
Will see if I can find it.

Correct, $760 shipped but bare calipers, no pads, no springs, no pins, no brake lines.
f30 370mm rotors are about $650 shipped.
Then you still need to machine the calipers, machine brackets, and get the rest of the parts.
Automatically, you are over $1.5k for "lego" kit
At that price you can just buy the front f30 kit which is straight bolt on.
You are looking at around the same cost for the rear axle.
Each it's own I guess.
I was quuted $4.2k for F&R stoptech

i see that it's old post, but better late then never

better to use 360mm rotors from m3 e9x, cause they have directional vanes, and they are 2 piece floating rotors.

f30 rotors don't.


and this difference is huge and touches both calipers - 4 pot on f30 works less, then on 2piece floating 380mm f8x rotor.

comparing f30 caliper vs brembo from cts-v/camaro makes me laughing - may be you saw them only on pics?

f30 caliper pads (114.5mm length)

6 pot brembo from cts-v/camaro (189.8mm length)


i've compared all this calipers in different configs and f30 calipers only for posing, not racing .

i've built more then 30 kits with this 6 pot calipers (with lug to radial mod) and most of them uses on trackdays and time attack.



some pics of my modification:






on our 135i with 360mm 1m/m3 rotor

[peterparker]

what calipers did you use??

and can you sell and ship the brackets to the USA?

I hope you know that the size of the pad will yeild insignificant improvement.

i've post this pics to compare calipers sizes.

f30 4 pot caliper too small, it will works fairly only on 1 series and, if you will not go to the track.

instead of deceleration you'll have abs chirring. i've tried them even with different excellent pads (rs29, ccr-g, mx72) and result wasn't good enough.

i understand that everything is relative, but with acceleration figures, which all this cars have, i'd prefer better brakes.

this is the same cts-v/camaro calipers, which have lug mounts from factory.
they are after my cnc work (and after that full respraying).

so, without this mod, brackets will be useless.

to help you understand this:

before modification


after


so, fixing mounts with my own design, sizes etc. this calipers also universal after mod, but they are not fully interchangeable with original brembo gt - you can't use my calipers on brackets from brembo gt kit, same in another way.
but yes, they are very similar with brembo gt, even on fixings. and they have same pad shape, cast dimensions etc.

Are these photos just for reference? Those caleper are different cast. Nevertheless, good job. Same was done few years ago with Touareg/Q7/Cayenne calipers on 335i with 370mm rotors from 7-series. Long before F30 came into the picture.

If you have issues with locking up the brakes and ABS interference I would look into tires and suspension setup.
I have been tracking my 335i for two years now on full f30 M Performance brake swap.
No professionally of course, I don't compete. They serve me better than the stock did.
Which from the above pads you liked the best?

of course, to explain peterparker that he can't simply go and buy them, to use with my brackets.

different from what?

i know that, but cayenne calipers are cheap and old model on brembo caliper, it's weight a lot, massive design. and you can't make really neat modification on them (due to pad pins location).

That is why I asked if the photos are for reference only or from the caliper that you actually modified.

hankook ventus td or z214 semislick, both with good width, 265/275mm.
suspension - kw clubsport/kw competition.

on same setup, but with 6 pot calipers deceleration really excellent.

abs doesn't chirping every time! but, it worked a lot earlier, then on 6 pot.

i understand you, and as i said earlier, everything is relative - of course f30 4 pot better then your stock brakes, but it's not wow effect, like on large 6 pot system.

i have a lot experience with this caliper on f80 and track use. caliper piston boots like embers after one track season

i really liked pagid rs29 pads, they work excellent on track, and same on streets (may be only first braking little bit harder, when the air temperature is low)

ouch, sorry, i misunderstood you.

this is my modified calipers - all this pics was made by me .

may be this pic will help?


real difference with original brembo gt only in bridge in the middle.
but caliper design without bridge more practical - easier to change pads, you don't need to take off caliper.

Great work slonik. Just wondering . What prevents you from using an axial bracket instead of a radial one and avoid all the machining to the caliper? too much material in the way for an axial bracket to fit?
Thanks

i love this calipers since first time, i've got them in hands. design is really beauty, they weigh a lot lighter, than you imagine, when you see their size.

with this large lug mount you have too small applications, where you can use it.
for example, you have no space to use axle brackets on e9x/e8x.

and with radial mounts they can be used in 95% of the cars.

from factory this caliper weight little bit more then 4kg, and after my radial mount mod this caliper weight about 3.2kg.

For many reasons but here are few main:
-caliper itself is large and using a plate will require rotors probably larger than 400mm
-centering the caliper with already existing BMW rotors equal to impossible
-caliper when axial mount will have to be positioned either more inward or outward relative to OEM caliper
-if you go with more inward no rotor would fit because it will not clear the lower control arm balljoint
-if you go with more outward the rotor would have to be very shallow and will not clear 99% of the wheels on he market
-radial mount can be easily adjusted to accommodate larger rotor

Thats the caliper I want.... 6 piston..... wish rallyroad would sell the kit.

[wshgrntd]

Would love to be able to fit these on the rear...

I may have a used front and rear kit available. One of my friends with the full kits may be pulling them off his car. Let me see what he wants for them.
