3) 3.45 LSD LSD fully rebuilt(bearings and seals) with an upgraded GKN Viscolok 7 disk LSD unit. $2200 (shipped)

1) Large Case 3.91 LSD : Great upgrade for E34/E31/E32 8 and 12 cyl. cars, makes the car feel 500LB lighter, acceleration is greatly improved, biggest bang for the buck upgrade you can get...car comes alive!
3.91 LSD was only offered in the US E-34 M5 up to 7/91,remaining years 92&93 used a 3.73 gear ratio.

2) Large Case 3.15 LSD Upgrade for E31 850i 6 speed, E31 850ci 5 speed automatic, marginal upgrade for E31 840i 5 speed automatic and E34 540i manual.

3) Large case 3.64 differential, great upgrade for 5 speed automatic E31 840i 840ci M73 850ci and some other BMWs

4) Large case 3.45 differential, perfectly balanced upgrade for 5 speed automatic E31 840i 840ci M73 850ci keeps the highway RPM reasonable at about 3k at 80MPH.

These differentials are a direct swap, all you need to do is swap the output flanges and the back cover, in some cases input flange.

Would you happen to have or know of anyone with either 2.65 or 2.81 ring and pinion in 210mm. I don't necessarily want the diff, I just the need the gear to swap into a E9x M3 diff. Thanks
