I think the Getrag is more than capable of track duty. Might consider a lighter flywheel and clutch assembly?
Not sure how club racing is in the UK? But, modifying the drive line ie. engine swaps and or even transmissions can move you into another class in BMWCCA and SCCA racing. The idea of this is to keep the costs down and the playing field level.
