Thats about right. N52 is about the same mass.
Reason for the z4m being over 100kg heavier is engine (30kg or so) but also dual backbox exhaust (about 15-20kg, the complete exhaust is bigger/heavier), 215 diff (lsd), hydraulic steering and bigger brakes. And countless little differences (propshaft, gearknob
, extra oil cooler, etc etc). It all adds up.
