The 2000-2003 BMW M5 and 540i also use a Getrag manual and there have been epic discussions on the BMW forums on this topic... the verdict is that anything but Royal Purple in a Getrag could ruin certain tranny components (ie, no Redline or Amsoil).
Even though I have Redline in my ZX3 (with good results), I took this well researched advice with my 540i and used Royal Purple. It has made a noticable improvement in the shifting and, after 25,000km of driving, it is still shifting great.
I will be putting RP in my SVT soon.
