X5M F/R Brake Retrofit on 35d/35i experience
I'm interested in comments from anyone who has done this. I've read a few posts that suggest the front is pretty straight forward and bolts right on, but the rear may be a bit more challenging. I have a 2013 35d sport - 20" 214s. Thanks

Just waiting for the weather to get a little nicer here and will be installing shortly along with ecs ss brake lines. As far as I know, you need to have the correct caliper carrier for the rear calipers to fit over the larger rotors.
I went with the M performance retrofit kit for the f15, which comes with all the calipers/carriers/dust shields/ supporting hardware and will mount up to the e70. Was able to sell the rotors that came with the kit and picked up some F85 rotors for a bit more. |

Smyles - to be clear, you're saying the E70 M rear brakes are the same as the non-M? I was thinking the M had a larger rotor and thus a different caliper and potential mounting.

Same rear calipers but larger rotors. The caliper carriers from the M is what gives you the additional clearance needed (part# 34217847226 / piece left of the rear caliper in the pic). It is also necessary to have ISTA so you can run the bleed/dsc routine to properly bleed the brake system, not possible to get 100% of the air out manually.

I've been running the fronts since 2014 on my 35d. I've gone through one set of pads and rotors I never bothered with the rears

Same as rear that's bolt on as well just need the caliper hangers as the rear calipers are all the same from M to none M. Just have to enlarge the opening of the rotor slightly I think as the M's have a smaller hub ring.

Also, if you go with the F85 rotors be sure to order two set screws for the front rotors, they have a smaller head than our gen. Current set screw will not tighten flush BMW - 34111123072 M8x12mm hex bolt |

Good to know. Don't get me wrong I wasn't doubting you since you had done the conversion but the hub size being different one would have assumed the rotors wouldn't have fit. I wonder if the X5M has a tapered hub???

So this mod is actually 100% bolt-on. Which is really nice. Are there any other pad options for the front aside from OEM? I enjoy not having to wash my wheels after every trip.

Was hoping hawk made ceramics for the fronts since I already had a set for the rear but no luck so ended up using oe f/r. Other than that I haven't seen any other options for the fronts. |
