HAVING SAID THAT.
All the 3 series have the same basic hub design. The difference between the 325/328 and the 335i in the rear, is the actual parking brake mechanism (in addition to the rotor size, of course). You've probably already know, you can bolt on 335i rear brake rotors and caliper and caliper bracket, but you will LOSE the rear parking brake functionality.
When UUC used to offer their Wilwood big brake kits, what they did was use rear brake applications from the 330 on the kits designed for the 323/325/328, and insert a "ring" inside the hub to accommodate the smaller diameter hub of the 323/325/328. One kit works for all the E46es except for M3s. I suspect the E9X is the same way.
RB IS developing a one piece replacement for the 328i I believe.

but i just don't want to lose the function of the parking brake.
