Could be interested if it's a straight bolt on or the E31. Will do some research.

3.91 is a very high ratio for V12. you will be reving the tits out.

I have a LSD in my 750iL you are most welcome to, havent got it out to check the ratio yet, but will be lower than 3.91

e28 case wont fit your e31 case .

you need e34 or e32 large diff case .

but you could swap the internals into your diff case or another e34/e32 type

3.91 will speed things up in your 850 but wont do your mpg any good :)

3.91 seems to be a pretty common upgrade. Think stock is 3.15 or even 3.64 in the 4 speed.

Found the receipt, 2 new clutches, replacements , so not extra. Make an offer - can also supply axles etc for extra if required.

Still have this kicking around in the car. Offers with whatever axle / subframe parts you need to go with it. Will probably remove after christmas and try and sell it for real.

Bump. Currently making an excellent object to stub my toe on and trip over when moving the bikes in and out of the garage.
