Interesting topic and opinions.

My cobra although not a BDR is a UK version RamSC I have fitted a 675bhp nascar based alloy engine with race box etc, and all the good AP brakes, 8.8 irs with Eaton carbon posi and on it goes, there isnt a decision on whether I should run an open diff or LSD because an open diff wouldnt cut the mustard, the decision is more like either LSD, locker or a spooled diff. All the cars I have driven with an open diff I have soon found the inside wheel generally breaks loose with loss of traction.

I am no M Schumaker, and probably most of you BDR drivers with BMW rear end and good suspension design makes good use of an open diff which is fine for most drivers, but for serious horsepower and track use the open diff is a waste of time period, you dont see race cars with open diffs unless they were little light Lotus type of cars of the 1960's which never seemed to really need a LSD!

Interestingly enough back a few years when I had a Bathurst Monaro and a friend had a Falcon XA GT 351 both had LSD and on a wet off cambered road these cars could easily catch out the inexperienced drivers when you gave them a heap of gas which could result in a spin or tank slapper, they didnt have good steering either....!

I do apologise for giving a non BDR opinion but I am bored and have posted for a while.
