Apparently all Apex 18s clear: https://www.e90post.com/forums/showthread.php?p=20391638&highlight=Apex#post20391638
Everything back together and pedal feel is nice and solid. I'll go for a nice back road hoon in the morning to bed in the brake pads 
I need to get my wheels refurbished now as the new calipers highlight how bad they are!

nice. So what did you do to fix the brake lines?
As is, they are ok. There is maybe 2-3mm of play in the bracket mount, ill get some spacers/washers to get rid of this, supposedly a common issue with aftermarket lines
Yes, there are quite a few OEM BMW 18's that fit over 370mm rotors/calipers, they can be found by searching through the F30 performance brake post on e90post. Also, most if not all Apex 18's will fit over the 370mm according to what Apex told me.
There should be a washer(thin) between the bracket and the stainless line tube nut, that's how ECS and stop tech are.

Has anyone heard of the tie rod ends scraping on the rotors? I removed my dust shields thinking that might be the issue but now the sound is more thunky or clunky, before it was a clicking/clacking and now it seems more solid. This is inline with the tie rod end making direct contact with the dimples on the rotor rather than rubbing on the dust shield.
I can't prove the rods are rubbing the rotors directly, but I do know for sure there was contact when the dust shields were there:

I'm just now starting to lay out a thread on a Z4 big brake upgrade which I've been working on. It includes use of F30 front brakes. some of that may be of interest to people that come to this threat, so I thought I would put a link here. My thread also includes upgrading rear brakes which on the Z4 adds the complexity of EMF.

I ordered eccentric bushings and new e60 rotors so my rears are finally going on.
I've had the fronts on with the M£ master cylinder for a while with no issues
@doublespaces I recall that you have an M3 steering rack .... And the penny has JUST DROPPED for me at least.
IN PeterY's track toy with a licence plate thread he fitted an M3 rack but shortened the tie rod ends and for the life of me i couldnt figure out why he would do that ... i mean no where else did i see that done(doesnt mean it hasnt happened) Its likely why your having your issue and no one else does. The M3 rack or tie rods are likely a different length

I've got 335i rod ends on and they don't hit the rotor I took some pictures the other day. I'll pm you.
Hi guys, I ordered this kit for rear breaks install from 55parts.de and they claim that it works with OEM rotors, if I understand correctly. Is it possible?
Thanks

sure, will do. Unfortunately the Germans forgot to send me the part that should center the rotors
I have the tie rod hitting the shield. Nobody else had this issue with a stock e90? I will remove the shield and see if it clears the rotor but it looks like it won’t
I forget what happened but the problem I'm having is still present even with no dust shields.
I think it's related to my m3 steering rack. Sometimes I hear it thunk when I make a sharp turn. Might have been damage before I got salvaged. Otherwise, maybe wheel bearings.
As to this issue, I do recall the scraping but I don't recall ever finding a solution. Just know I removed the shields. Maybe I'll go back under and take a look.
I do have aftermarket tie rods. Combined with the M3 steering rack and the F30 breaks, God knows what's going on.

I am stock rack and tie rods. I am lowered on dinan springs and koni actives. I think I will first try and cut the shield where the contact is. Then I’ll try removing. Lastly grind the tie rod a little. Not sure I can live with it hitting the rotor
First I'd try to deform the shield with a pry bar or two, to deal with the noise - just because that's easy to do. Next I'd remove the shield as it serves no particularly great purpose.
I don't know why the tie rod would actually hit the rotor - it's a fixed distance and not much flex there.

There is no play on the shield between the rotor and tie rod at that point. It will be very close. I’ll give it a shot
