Thanks :thumbsup:

These are huge in the flesh! Pads must be twice the size of the standard brakes, I cannot wait to get these on!
Fantastic mod Steve. I would love to do this upgrade. Do you have any part numbers or list of parts required. I guess I have the 330mm front discs as per 28i. Any info greatly received pal.

Yes you’ll have the 330mm discs. These are 340mm so not a big difference but the calipers look great!

I’m away at the moment but once I’m home I’ll dig out the part numbers :thumbsup: For ease though these are straight from any of these cars...

Any F series with upgraded M SPORT brakes (could be a 120d for example with the upgrade)
Standard fit on an M135i / M235i

You’ll need the following

Disc
Caliper
Pads
Pins and Clips (these should come with the calipers)
Brakes fluid


They’re a direct bolt on fit.

I love them :thumbsup:

Just be aware that the M Performance upgrade is a 370mm disc I believe and the calipers are different. Still a direct bolt on mod but if you’re buying calipers separately on eBay just make sure they’re correct as so many are mis advertised!

If buying from eBay/forum people (I'm not implying anything regarding this forum) have a quick scan of this post on babybmw: http://www.babybmw.net/forum/viewtopic.php?f=7&t=110268

Brakes from an F series 1'er you say....um....wonder if Deb will notice I've nicked her callipers? (before she needs to brake!!)

It’s from eBay :thumbsup: they have them in a uk warehouse so was delivered within 3 days of ordering. Very impressed, fits perfectly, it looks great if I do say so myself!

I was always under the impression that the hubs on the 35i and 35is were different to the rest of the E89 range, so am I wrong on that or do you need a caliper bracket to mount those calipers on the 35’s..?

Anyone know? :?

I know someone else with a 35i what has fitted them directly with no issues :thumbsup:

Yep Ive seen them on a 35i, so the hubs must be the same as the rest of the E89 range but just use a smaller caliper with the same bolt centres. Unless there is a bracket but I’ve not seen any and I would think the hubs on the M car would be fairly beefy.

Very nice upgrade, the calipers are a bit weedy looking standard. :thumbsup:


Any light shed on the turbo issue?

SteveSmith, I do think the rear of the E89 needs a little something... but do you think a black spoiler would work on Valencia Orange? :scratchhead:

Yes! Massive failure of plastic boost pipe below wastegate coming from the intercooler!! Booked in to bmw on Thursday, should be a quick easy fix.
