Thanks italy for this. Im looking to upgrade my worn out brakes to a set of F30 m sport brakes right now, i assume that's the same as M235i calipers right?

Your post really helps me out. I'm going to buy a set this weekend.

Take the 370mm BMW Performance Setup. This is definitely the better choice for a comparable price to the 340 mm set.

This is what I ordered the day before yesterday, I am off next week (gone skiing, what else), but I aim to have it installed once I am back, will report then (supposedly this sould be a straight PnP)

NO this is the upgrade for <35i/S, because the rotors are smaller than the OEMs (not allowed for Europe, because downgrade).

THIS is the upgrade for the 35i/S:





BMW Performance Brakes with 370x30 mm with 4 piston calipers.
P/N's are mentioned before

Thanks I just realised Euro 35iS are 343 and those others are 340, thus yes need the 370. Thanks again.

Would the base 335i F30 caliper (the ones that come with the 340mm rotors) be PnP with a M-Sport rotor (370mm) as the calipers are interchangeable? Or would there be other parts I need to buy to make them work?

Seems like purchasing the 335i stock caliper and buying the M-performance rotor stand alone would be a better deal. That, and you get your choice of color when having it powder coated.

I would think that you would need a different bracket at a minimum in order to space the caliper enough to clamp the bigger disc. But it would not also surprise me if the piston sizes on the brakes are different. Generally speaking a bigger disc needs a smaller piston in order to maintain the same braking force as a smaller disc.

No problem mate. They even have 348 mm.

Please see my post #32 - there I already mentioned the correct p/n's for the brakes.

And no, the caliper for the 340 mm disc is not p'n'p with the 370 mm disc. There is no spacer bracket available.
The best deal for you is to buy the complete 370 mm kit.

If you want to powder coat the calipers, you have to disassemble the complete calipers anyhow (incl. pistons ect). Sand blasting must be done for all calipers as well - so you have the choice of color also for the 370 mm calipers.

You can also paint the calipers with heat resistant paint - the OEM calipers are also just paint coated. So you just need color which resists min. 280C.
By using paint coating you can also tape the pistons and you do not have to disassemble the complete calipers (although the complete disassembly would be the more quality way to go also for paint coating).

Correct regarding the calipers/ discs with the spacer.

I think the pistons should be identical because the repair/ sealant kit for the calipers are always the same as from 114d to M4 and even i8 (P/N 34116850935).

Please explain your theory regarding the smaller pistons at bigger discs more in detail.




The i8-brake could perhaps also fit to the Z4:
Rotors: 340 x 29 mm: 34116858623
4-piston-calipers (black&blue painted): 34116868231 + ...2
Brake pads: 34106866072

True...Would they bolt on as is with the OEM protection plate? Has anybody actually fit 370 discs because the pnp comments refer to 340/30 rotors, correct?

If I'm not mistaken, both 370mm and 340mm rotors are PnP, depending on which calipers you get.
M-Performance caliper uses 370mm rotor, PnP
335i base brakes + Sport brakes uses 340mm rotors, also PnP

As nuebbes mentioned (although have not confirmed myself, based on what he is saying though), the M-Performane calipers and Sport calipers although the same, uses a different bracket, so getting Sport Calipers and buying 370mm rotors would not work.

For those who have done this upgrade... since it is not officially approved by BMW for the e89, did anyone get coded afterwards? I know for both the E9x and F30 Performance brakes, BMW "requires" a DSC re-coding in order to retrofit them. Any down sides to not coding? Would a dealership code a E89 that is NOT approved for these brakes?

The 335i(x) rotors (are we speaking of e9x gen?) are definitely 348mm (see my signature, daily car mods)

Clarification: Everything I said in the previous post was in regards to the F30 (e.g. M-Performance Brakes being 370mm, as for the E9x the M-Performance brakes are 338mm in diameter)

The F30 335i rotors are 340mm, as the E9X calipers are not "big brakes" so I don't believe ever made it onto this list as as a brake upgrade.

Thanks for clarifications.

Partially off-topic: the ex-Z4 OEM calipers, carriers, pads and rotors resurrected.... quite unsurprisingly, they become a PnP front brakes upgrade to 320d e91 MY2005 ....

firstly thanks for such a great thread! really helpful

secondly some of these brake setups look amazing esp love pavprochs pics above - well done

Please can I get some advice?

I have a 2011 z4 e89 23i from London, UK. Should I get the f30 370mm pbmw front kit? Any news on a ebrake compatible rear kit or it the 35is rear the only option available?

thanks in advance!

this is my z4 with 19s and 12+15mm spacers:

Get this instead of you are not planning to heavily mod your car. In my opinion you only need a brake upgrade if you have the 30i, 35i or 35si or if you want it for looks or gonna do heavy performance modding.

This looks good and really affordable. My friend has it on his E36 M3, the brakes saved his life once. Lol

great thanks. i think this is the e90 kit. others have said this is the most cost effective option. i dont think the rear is compatible but i may use the 35 is rear for that.

i want it for the occasional track day and for the looks too. i'm not planning on heavy modding but suspension and exhaust are minimum mods

its a pretty quick car in manual with the 2.5 straight 6 very impressed with the power
