True: you can set the fixation with plate type, and yes: that works very very nice for WTCC/BTCC, BUT: do you want to take you're diff out for every other week-end you go driving ? Unless you've got the budget (and the personnel) to do so (changing diff all the time), Torsen type is the way to go. (in racing you have to adjust to any circuit anyway (gear ratio's etc) therefore it is not very difficult to change the LSD setting/plates)

Also: driving with a plate diff is more difficult then with a torsen;
