Fronts are on, haven?t done the rear but that might change if this works out without machining

They do make the two piece ones though...

I know for e60 and e90 M cars yes, but not with aluminum hat. I have not seen any for non M. Post part numbers.

I mean that they make the two piece dimpled rotors I linked to in the other thread.

I have probably missed the post. Perhaps you can post the link here as well.

Hey mariusc, can you also confirm that the handbrake shoes are covered etc ? Im perplexed. How can the rotors vary THAT MUCH? These discs would be all the way out on a stock e60 surely ??

Are you sure that those are made by Zimmerman? I know these are: https://www.ecstuning.com/b-zimmerma...4106797603zkt/

I have not seen any 2 piece advertised, packaged and sold as Zimmerman here in US. Maybe is different in other markets. If I order Zimerman under that part number I will receive 1 piece. There are other options for 2 piece like: Pronto, Dura, Pilenga, Vaico... http://www.ebay.com/itm/BMW-3-Series...VZy6qM&vxp=mtr

The rear rotors are one piece steel.
Measured today and the height is 61 mm measured from the hat (lying down) to inner rear surface. There is a lip which extends the inside total height 2.5 mm.

The handbrake works good (but I didn't adjust it properly yet).

There was some rubbing between the inner "lip" of the rotor and the sheet metal between the dust shield and the rotor. The sheet metal is a cover behind the handbrake which I bent inwards with a hammer and a flat head screw driver. I think it's all OK now, but didn't have time to do a test drive this evening.

Here's a picture of the metal that needs to be bent inwards. You can see the rotor has already grinded it a bit.

OEM are 63mm and require caliper to be milled down. Since yours are 61mm that expalins why you didn't have to. Great job!

I just bought the M Performance kit (Yellow)

I may be getting the caliper milling confused, but my understanding is the rear calipers must be milled to fit, does this mean we no longer need to do that if we use this rotor instead or is that something different?

I am going to assume the milling of caliper to create fitment to the car is still needed, and this is in reference to fitting different rotors to the car.

So, what is the recommended rear rotor? I still need to buy those and don't want to spend a lot of money.

I don?t know why that I thought they were 2 piece... I think one of the eBay adds said it in German. 2 druck

It's say 2-piece. You are correct. But only on out of US websites. I have ordered few of these in the past for the swaps I have done and received 1-piece as has mariusc

I sure wish that retrofitting the F30 sport rears to the E90 335i cars was much easier. Milling the rear calipers & maybe using an E60 335i rear rotor is good. But there still seems like to much guess work, trying to tolerate varying clearance issue & overall out of the box precision to make this plug & play yet.

You would think one of use would've simply taken a 3-D model of the ECS bracket, made some very & minor adjustments & made this kit a precise & painless kit for us all to enjoy buy now. One can only hope right... ?

Just my .02...

That is not an easy way to do it as the ECS bracket needs the caliper to be milled down even more by removing the entire fastening bracket and drilling new holes. See the modified caliper here:


I didn't have to mill down mine, but I'd be sure you could do it yourself with a file since not much will have to be removed anyway with E60 rotors...

Did you still elongate the holes or just drill them out mariusc

They had to be elongated. I did "some" elongating at first, then mounted the calipers. The pads was then hanging just about inwards of the inner wear surface on the rotor. Elongated some more, until the pads leave appoximately 1 mm edge on both inner and outer surface of the rotor.
