Just looking for parts as I am on lowered suspension, and these seem to benefit the springs. I'm not looking to do coilovers anytime soon so small upgrades to the stock suspension is what I'm looking for at the moment. Besides the functionality aspect I'm just looking at more rear camber adjustment for aesthetic purposes, though I agree the front honestly needs more for high speed turning/cornering.

When you lower the car you change the roll center of the car. Typically different shaped arms are used to correct this, but unless you've done the measurements and know where the roll center is, it's kind of pointless to spend the money if you don't know where you're correcting to. Additionally you'll probably want to consider adjustable end links if lowering a lot.
See my video below at 3:50 why you might want adjustable end links.
More rear camber with as little as BMW provides up front will just make the car understeer more. That's actually the reason BMW specs so much rear camber stock from the factory, so that you understeer instead of oversteer.

You can run different mfg's adjustable arms, however you'd probably want to run the same brand on the same axle (like all SPL front and all Hardrace rear). Sometimes they can do some funky things with the geometry of their new parts and not make it obvious. On the F3x platform someone found out that you can't JUST run SPL LCA/wishbones, and that you also need to get their tension strut arm too.
