Where did you get your calipers painted and are they powder coated or just painted? Can you post some pics of them more close up? I love seeing them in that perf yellow color.

Yes, I will try it soon

and I got it painted by a local shop, its paint I believe. I don't have pic of mine on hand but johnniewalker had the same caliper that painted by same guy. Actually I was following his step
Here is the link of his pic. http://www.e90post.com/forums/showthread.php?t=722694
I also found DESI4life's post on #8 in this thread which confirmed our thought.

So I assume the rotor you found should also work on 328xi and no need to change the hand brake shoe? What do you think?

You can test fit it and if it doesn't work you can always return it. I did that with a set of rotors I bought from a dealership. Just be very careful and don't damage them or get the dirty. Test fit them without any pads in the caliper.

Let us know how the test goes. I believe that post from Desi4life only confirms what we know about the brake shoes. The link e90pilot provided is different in that it is the right rotor diameter and width.

I have an unanswered question. Is the 135i rear caliper straight bolt up? Do you need the special carrier?

Thanks!

Rear Performance brake disc and caliper fits bolt on, it also fits stock parking brake. I just did install full Performance BBK front + rear on my 325 xi. Pics attached.

I went a little different way with the fronts, we machined the bracket instead of knuckle.

The part number for rear Performance brake disk is 34216795755. This should fit US 328xi.

And btw, the rims are solid forged 7,5kg per rim 17"8J. Russian made @ 400USD per piece, 1,6 grand for a set

Yes it is straight bolt on with the brake disc number I posted. Because Performace rear caliper is the same as on 135i just different color.

Just remember, you need the 180mm hand brake shoe. If your car doesn't have it you'll lose the ebrake. I'm still working on a good way to get it all to work without hacking anything apart.

Thanks for notice. Mine is a e90 328xi. According to realoem, my car has 185mm handbrake so I think I will be fine.

Hi Yury. Thank you so much for sharing. Looks great. I cannot see where exactly you machined the bracket on the front. Can you please explain better and highlight in the picture.

Why not do what member avocet did and weld the two brake shoes together to fit? 325 and 328xi.

I though about it but I kinda wanted to do a neater job without having to hack up the brake shoes.

See the picture attached. Both ends of the bracket used to be identical. Now find one difference

[Yury]

Just learned that BMW Performance brake rotors manufactured by Zimmermann. It would be cheaper to buy direct.

[Josep]

Any updates?

at the end, what is the disc that fit in the conversion?

I have the front calipers with ECS discs and brake lines and rear 135i calipers but I don't know what disc will fit perfectly.

[Josep]

Any update about rear discs that fit 100% ???

What about a exact copy of the oem but with a bigger diameter, 324mm???

Yuri give you a part #34216795755 Why don't you purchase these rotors?

[Josep]

That one is 324x22mm.

I need it 324x20mm. With the same spec as the e90 oem (like offsets)

324x22mm vs 324x20mm and both are same offset? If yes,then is beyond my intellect to understand why you would not get them.
