rear diff option for 1988 520i e34

BimmerD00d,
Appreciate for your help on exact url on Bruno's homepage. I can't seem to find the chart...

probably a .81 od like our sohc motors, the twin cam stuff had the close ratio tranny with no od

it won't be too bad as your car is not as heavy as ours

OK, i believe you have an M5x B25 engine, which rear differential would be different to earlier ones.

My gear is std gearbox with OD. and i realize, it will kill the ability to move the car. A M20B25 conversion is also on the way...
