As a slight aside, I have a question.
You are all talking about using oils with friction modifiers in the BTR axles because of the LSD.
Surely not all BTR's have LSD's. I can't imagine there is a limited slip diff in my BTR axle 4/4.
Which cars have limited slip diff BTR axles?
As standard, the BTR axles for the 4/4 and Plus 4 are not LSDs. You can have it as an option on the Plus 4 although I believe a small number were fitted as standard a coup,e of years ago. The Roadsters have LSDs as standard.
