Glad we are on the same page there. We will have an excellent solution requiring only 3 to 4 mm to be removed from the caliper. No mater how tight their safety factors may be, we will be will within tolerance.

Did you test fit / measure to confirm that they cover the handbrake mechanism well enough to prevent dirt from getting in there ?

Let me know ...

I will be sending the calipers out to the machine shop this week.

I have completed the test fit of the front calipers with my track wheels (Apex EC-7 18X9 ET31). They fit wonderfully with room to Spare...

yes, is only 3-4 mm difference. 336mm 335i rotors are 67mm tall. Plus you have the dust shield and the park shoe plate. I do not foresee issuee with that. I ran 18X9 ET31 as well.

Is there any chance of these calipers fitting behind the 18" 313 wheels? Fronts are 8x18 ET:34, and rears are 8.5x18 ET:37.
Thanks.

Thanks.

many reported that they do not i don't even think they clear the 19's

[R99]

They do clear the 19's - there are pictures in this thread with F3x 370mm Brembo & OEM 313 (19")

For the 18's, the guy who started this thread had to shave the caliper to get them under!

I think it depends on the thickness of the wheel barrel!

No, it depends on wheel design and wheel offset, not thickness of the barrel. Plenty 18" fit with out any modifications. Also, a lot of 19" do not, especially those multi piece closed spoke design like BBS LM for example.

No, you can not fir the 18" 313 style even over the 340mm F30 brakes.

Thanks guys. Well that puts the kibosh on this for now till I get some 19's

is there anyone who is starting service where they would modify the rear calipers for price feuer maybe?

These two guys can do it too:

how much would you charge me?

My guy in Tampa FL charged me $200 or so to do it. He has a custom machine shop specializing in BMW's and does custom machine work, i.e. manifolds, intercoolers, etc. He made a custom fitting for mine since it was the first one he had done. You'd need to cover the shipping though.

$200 is about right since the shop need to stop what ever they are doing that pays the bills and re-tool for this little job.

[wshgrntd]

thats fair...

[R99]

Any further info on the new disc suggestion - should this make the job easier?

I still keep coming back to thinking about doing the rears to match my 370mm fronts!

I wouldnt be able to do it myself though, and nobody has done it in the UK yet, so we don't exactly have an abundance of info / shops capable of doing the work!

I disagree! Info is available everywhere due to internet. Additionally, in EU finding a small machine shop is a lot easier then US. I know first hand.

I agree, its great to get info from the internet - and for things that a direct fit or plug and play - I'm always happy to go along with the info / advice!

My 370mm brake upgrade was so simple thanks to the info you and the rest of the guys have provided in the thread!

My main concern is that with the rear, there is just one opportunity to get it right!
Like someone else has posted, it would be great to have somewhere offering this service - preferably with the new disc that has been mentioned (by you) from the 5 series!

Has anyone used that disc yet - as if they have, then I guess there will be new measurements to mill the caliper to?

I can confirm that the 19" style 313 do fit over the caliper but a spacer is required to clear the spokes.

It looks like a 3mm spacer would do the trick but I am using a 12.5mm spacer so I had no issues.

As for general wheel fitment, there are two factors to watch out for:

- Drop center (How the spokes come towards the hub)

- APEX EC-7 18X9 fit without a spacer but Style 313 19X8 need a spacer.

- Barrel design

- APEX EC-7 18X9 have more room in the barrel than the 19X8 Style 313.

In response to feuer's proposal for an alternate disc, I physically measured the proposed discs:

F30 335i M Sport:
BMW: 34206797600
Zimmerman:150.2920.20
Offset: 66 mm
Drum depth: 61mm

E92 335i:
BMW: 34216855004
Zimmerman: 150.2920.20
Offset: 66 mm
Drum depth: 61 mm

E60 535i :
BMW: 34216763827
Zimmerman: 150.3461.20
Offset: 63 mm
Drum depth: 58 mm

The E60 535i disc would definitely work and require 3mm less material to be removed. However, for a car that sees Canadian winters and salt, I have elected to go with the F30 M Sport rear.

In an effort to give back, I spent a few hours with the Zimmerman catalogue which shows the critical dimensions for each disc but I was unable to come up with a better option.

Shout out to feuer for having done all the research !!

And off set. Z4 19" 313 style fit as they are 28mm vs 38mm for e9x wheels. But they are very rare.

Could someone do a write up of all part numbers and options and put it in one document or post. Just a little hard to follow each response in here..


Thanks,

Here is a photo for F30 rear rotor on E90. Looks like there is few mm to spare so E60 rotor will mount flush with the brake shoe backing plate.
