They appear to be the same size, no additional hardware required.

The SuperPro ones appear to be softer than the stock so I didn't actually use them.
The ride is somewhat harsher/stiffer, the steering is noticeably more responsive and there is certainly less understeer.
I was only only able to get -1.15 camber symmetrically (I could get -1.15 one side and -1.45 the other so I made it equal at -1.15).

I have the Superpro camber bushings (SPF-4303k) fitted on my F31 xDrive too. I was able to get to about -1.2 on both sides.
Note that although the camber/control arm bushings fit xDrive, when I tried to fit the Superpro tension strut/caster bushing (SPF-4306k) it was too long to fit into the subframe mount on the car. The bushing pressed into the arm fine, but couldn't be mounted to the car. This is weird, because Superpro's European site said it should fit.
With the Superpro bushing I noticed no increase in NVH, and a very slight steering feel increase (not really noticeable unless thinking about it).
I'm trying to get a hold of KMac's +/-2deg camber bushing, and have given them measurements of my caster bushing to see if I can get an adjustable one there too.
Interestingly, KMac said that Raymundo received both the camber and existing KMac caster bushing for his xDrive car, and didn't report any fit problems with either.
