And yes, there is some macpherson camber gain correction in the F8x upright, though I believe there is in the E9xM unit as well. The whole assembly was marginally lighter but I can't remember all the details, I think most of that was due to hub weight.

Basically boiled down to cheap easy part access for me, got a screaming deal on cleaned up F8x uprights, and then easily using the stock F8x BBK later as I specifically didn't want the E9xM calipers. Pains me enough that my rotors won't match perfectly.
I see. So you are going to use the stock F8x caliper and rotor at some point? Sorry, i am full of questions but i love learning about this stuff and planning what to buy next!

Yeah the plan is to do the full F8x BBK later if I find I need more brakes. Cheapest way to get a true BBK as far as I know. Trying to future proof. The bracket is from Hydra.

I started tearing apart the front suspension today. Along with the M3 spec custom built 3DM Ohlins Road and Track coilovers, the upright needed replacing with F82 M4 parts, and I swapped in a different caliper bracket and all hardware.

After breaking a couple Crapsman tools, and realizing I don't have a Torx not big enough for these F8x hub bolts, I snapped a couple photos to demonstrate the carnage, and to point out a surprising find.

Converting from the E82 nonM knuckles, hardware, and brake caliper brackets to F8x parts and the Hydra Performance E46M3 CSL brake adapter saved about 2 lbs of unsprung weight.

Wow!

Lol patience I didn't get that far.

PS gonna have to get some bungee cords or something, the zip tie holding the caliper failed badly. Luckily I have new SS braided brake lines.

FWIW, I had the HFT assortment and they were crap; one in three would fail tightening them. Threw them out and now I only buy Panduit cable ties. I usually use baling wire to hang calipers, though.
