And here's a pair of caliper brackets I CNC'd out of aerospace aluminum alloy. F8x knuckles + E46 CSL rotors + E82 Brembos anyone? 
Thats... quite a mashup of brake parts...And here's a pair of caliper brackets I CNC'd out of aerospace aluminum alloy. F8x knuckles + E46 CSL rotors + E82 Brembos anyone?

I wanted "M" front geometry, which runs different ridesteer and ackermann characteristics compared to non-M, in additional to having a stiffer design, losing less camber, and introducing less bending/friction into the strut under load. I originally wanted to use the E9x M knuckles, but they run a different caliper bolt spacing, which makes it impossible to run the E82 brembos with CSL rotors. The F8x knuckles use the same caliper bolt spacing as that we do, which allows me to run the combination of parts above. Keep in mind that I am running 17s , so 345mm rotors are about the biggest that will fit, and the CSL rotors as you know are a high-quality, lightweight 2pc choice. Will also be adding ducts/scoops to maximize cooling, but more on that in due time..
StopTech 355 st60 fits on 17 apex wheels. That’s a much better setup than the e82 brembos.
No they won't, there is an 11mm difference in caliper mounting offset between the F8x knuckle and the stock E82 knuckle if I remember correctly.
Really on 17s? That is good to know. While I love the look of my BBS 19s Apex 17s would weigh alot less.
Quick test fit of the front upright/caliper/rotors/CNC'd adapter and everything fits like a glove, very pleased with that. Now to get off my lazy ass and put the rest of the car together
More to come...

What's the weight difference between the F80/CSL/E82 brembo setup compared to stock?
@ShocknAwe
Approx 3.4kg for the pair, with the billet aluminum bracket if my memory serves me correctly. Keep in mind that removing the counterweights off the stock front Brembos (as I have done) is worth another 0.75kg as well. Will be adding ducting to the fronts though, so we'll see how much weight we'll add back...

Pretty similar to my 2pc racingbrake rotors then.
Do you have any pics of the counterweight on the brembos you mentioned? What's the weight for? The stock E82 calipers are pretty hefty already.
@ShocknAwe
The weights I listed above are a delta compared to the OEM setup. You can see the counterweights/ears mounted in the pic below. They are held on by a pair of 5-6mm allen bolts at each end, and are very easily removed. Also keep in mind that the CSL rotors are slightly bigger than stock/Racing Brake rotors as well, coming in at 345x28 instead of 338x26mm.

Did you feel any ill effect from removing the weights on calipers? Extra noise/vibrations at all? Does caliper over heat eassier/quicker? I was thinking removing them, but not sure if i should.
@Dmak
None whatsoever, I've never seen any other calipers which use counterweights or anything similar...
On an unrelated note, looks like I'm finally going through with this....
This is a quick mockup, and endtanks/piping still need to be made obviously, but I <3 it!
