Gearbox oil

[orse]

Hi all,a quick question for you boys more in the know than myself.Wanting to change the gearbox oil but wondering what spec/grade to use.Asked at my local main stealer but the bloke did not fill me with confidence.I have a 1997manual 850 r estate.Will 75/90 gearbox oil be adequate.Have heard rumours of the R's having a type of lsd,is this true?Just purchased a 302mm front brake setup am i right in believing that the calipers and pads will be the same and it's only the carriers,discs and hoses that need changing?Thanks for any help members can give.

M59 is the 6 speeder correct me if i am wrong used in the later P2's...

M56L & M56H with various diff ratios feature in the 800 / 70 series.
