Gave the mesh inserts a refresh as well.
Also made hose holders for the shocks, both a horizontal and vertical version.

It's been a while, but now the rear brake cooling is done! Had to switch supplier for the metal parts and that took a while. Rear brake cooling installed on my E46 M3 race car, should fit nicely on the E8X Z4 M platform as well as E36 M3.
Cut away as much as possible from the OE backing plates but kept a small part for structural rigidity.
Painted the backing plates in place as good as possible to avoid the edges from rusting.
My backing plates (adapters/heat shielding in reality) with the 3D-printed funnel. Don't mind the rough surface on the inside of the funnel, it's due to no supporting material and the shallow angle of the surface (will never be perfect with 3D-printing). All funnels will be printed with support but it won't be perfect on the inside anyway, but a lot better.
Parts for the rear intakes (forgot the support brace though). Painted all the metal parts to protect from rusting.
Fitment and don't forget to use loctite on all bolts/nuts!
Designed the kit in such a way you only have to remove 1 bolt at a time so you won't risk missaligning the toe angle.
Here you can see the support brace installed.
Finished result! Very pleased with it and I'm anxious to see how well it will perform on track. Rear brakes aren't as impactfull as the fronts when it comes to braking performance (at least with stock-ish brake setup/balance), but at least it will help a lot with pad and disc wear. On my race car it will help more because I've moved the brake balance more towards the rear.

Individually they're 3300 SEK for the Race front bumper kit and the rear kit will be 2500 SEK, but if you order both or have bought a front bumper kit earlier I'll can give you a 500 SEK discount. So that's a total of 5300 SEK, shipping is 216-351 SEK depending if I can squeeze it under 2 kg (Expect 351 SEK).
And as always... No hose or hardware is included in the kits. Don't have the time to sort that out unfortunately. :|

The rear brake cooling kit is now done! A complete kit will be priced at 2500 SEK which is about 202£, if you've bought a complete front brake cooling kit from me before or buy both a complete for the front and rear I will give you a discount of 500 SEK which is about 40£. As always no hose or hardware is included and the metal parts are not painted.
I can sell rear intakes (with brackets) and rear backingplates/funnels separately if someone wants that, the price is 1500 SEK (About 121£) for the intakes and 1000 SEK (About 81£) for the backing plates/funnels.
Since I had to change supplier for the metal parts I went from laser cutting to water cutting thus the metal parts will have minor surface rust/stains on them. A small issue since all metal parts have to be sanded before paint anyway.
Complete kit for the rear brakes:
Only intakes/brackets for the rear:
Only backing plates/funnels:
Some pictures from the install of a complete kit on my BMW E46 M3 (Repost):
I started off with cutting away everything off the OE backing plate I didn't need, just saved a bit due to structural reasons.
Painted the freshly cut edges of the backing plates to prevent them from rusting.
The backing plates and funnels. My funnels were the first ones to be printed and no support was used thus the rough finish on the inside. All funnels printed to customers will be printed using support and look a lot better on the inside.
Parts for the intakles, bent edges and dimple died holes. Just painted with a standard single stage metal paint to prevent them from rusting. The backing plates should be painted with heat resistant paint though.
The kit is designed in such a way that you only have to remove 1 bolt at a time for the RTAB holder to prevent toe changes.
Support brace.

Looks great Andre! My only concern is does it interfere with the Z4 rear 'air dam' that is before the rear arch (not present on e46)?
I guess if it does it would just be a case of removing it, but perhaps there is a possibility of mounting it through the fixings for that rather than the RTAB carrier?
I'm tempted to add to your front kit but I have ap calipers on the rear and having measured both disc and caliper temps it's certainly not critical for my usage, I've only ever had issues when I left the TC on half way by mistake. Great to see a new option available though, thanks.

Thanks Tom! The air deflector is removable I believe, just like it is on the E46 M3 (mine didn't have any because it's a racecar). The design of the rear intakes is made this way to work both as an air intake and an air deflector. To retain the function it had from factory along with cooling the brakes. I can always make a custom air intake if you want to mount it in another way, no problem. I designed it this way in order for the kit to work with E36/E46/E85/E86 since they all share the same bearing carrier.
Just let me know if you want another desing of the air intake and I'll help you out.

I might be wrong but I don't think the M3 has the air deflector that the Z4 has? I appreciate your mounting solution will work with all those variants, but it would be more elegant for the Z4 I'm sure to use the fixings for the air dam. I'm with the car in a few days, will take some photos to show you what I mean. Maybe it won't make sense to develop it just for the Z4 though, I can understand that.

The E46 M3 has an air deflector but you're right in that it's not the same parts number as the Z4 M one. I'm open to developing a specific air intake for the Z4 M. 
Apologies I didn't get the time to lift the car but you get the idea I think. This piece that includes the air dam is bolted in and has some dowels I think to secure it. Would be cool to re-engineer that no? They are available on ebay for £10 or so here I think if you would like me to send you one?

No worries! I've thought about that but my Z4 M is standing all the way back in the garage on top of a car lift. No need to buy and send one I'll wait for summer and get my car down for the developement of a new intake. The problem with the mounting of that part is that there's VERY little room for the scoop/hose before it interferes with the wheel well. I'll give it a go once I can get my Z4 M down.

It's still for sale! Having some issues with the printer right now and waiting on parts, so I can't print right now but it will be back and runing shortly (hopefully).

The front bumper on the non-M is a bit tricker, I don't think many people would like to cut a hole in the mesh, maybe a control arm solution would work? I have such a kit installed on my M2 and it works great, also a few others have my kit installed with great results.
