Since you don't know, let me share. And it's all in the thread you got the photo from:

Well, for those interested. .....here's my (old) BMW rear end. 391 ration with 25% LSD.

Broke it after driving 1500km to the Australian Cobra Nats. Turned 8 laps before crunck! Turned a tooth. Make sure when you do your diffs that you DON'T re-use torque bolts and make sure you set the diff lap low on the teeth.
spookypt bought one of Reg Dodd's old race cars. It had been run all over in the USA and configured many different ways. At some point in the wear and tear the rear was reworked and the bolts were reused. There's your failure. Just the facts, has no bearing on standard road going BDR cars and certainly nothing to do with the 0-60 times here.
