Good comments. Rotora makes a 4 piston caliper that Evosport sells for $2,615, for the stock E46 M3 rotors . Maybe they will produce a 6 piston for the E92.

Edit: Just confirmed by Brad at Evosport, Rotora WILL have 6 piston forged calipers for the OEM rotors. More info available Monday. Brad will put together pre-release pricing

Group 5 Motorsport is another dealer. This is not the kit, but an example:

This is an owners report of a Rotora BBK on his E36 M3 race car:
