Idd there are no H&R springs for the 330e, but I use the H&R28662-2 springs from the 330d. Cars stays and runs perfect.
The ZF8HP can handle to 700nm but my friend Peter from Pureturbo has more experience in t and says it can handle lot more with no issues. It's the same gearbox as he 140i, 760LI etc...
