Yeah, I use E32 735i rear brakes (38 mm).
Ok, have to admit it is on a E30 that is some sort of a bastard. But as you know it is popular to bolt on the entire E36 CPT rear onto the E30 as a 5 lug conversion - so the information should be relevant.

I did a very quick & dirty static brake balance calculation (only based on piston size and didn't take the increased rotor size into account).
Piston Diameter BEFORE = 48/33 mm (front/rear)
Piston Diameter AFTER = 60/38 mm (front /rear)
So before I had a distribution of about 68/32% and after I have a distribution of about 71/29%.
Nevertheless, I removed the factory brake pressure regulator and replaced it with an adjustable brake pressure regulator from Tilton to be able to fine-tune the balance.
I just got the car through state inspection (so you can drive on public roads) and just made the very first shake down (the car has been completely disassembled over a period of 5 years - so I might have forgotten a bolt or two).
And it's still like only +5 degree C here, and I only have ordinary summer tires so can't do too aggressive brake tests. Well, I can say that the front tires are still locking up first at least
