I think BMW lied again as the ZF they put is cheaper than the Getrag 420 of the M3.
There is a shop in south africa that has a 1400 whp turbo z4m coupe and they put the 6 speed from the M3 in it.

Correct, but with an unbelievable amount of fabrication work, to the firewall and floor as the getrag is a wider transmission, and shorter too. Remember the M3 is a wider car and you sit on the floor pan. Our beloved E86 chassis we sit within.
We have a S54 Z3MC, E46M3, E86MC and E86 3.0si and never experience any issues with shifting up or down, the proviso here is: the engine and gearbox must be up to operating temperature. From cold, yes, can be baulking a little. Royal Purple or Redline oils may assist here, various race shop technicians swear by these products to solve the issues discussed above.
