| I'm looking at swapping my diff to a LSD. I have a 318i, and I've heard that you can swap in a LSD from a 325i (I believe). If thats the diff that I heard about, at 70 mph in 5th I'd be at 4,200 rpms. Has anyone done this swap? or swapped for a different diff? or does any one know the ratios for the different E36 diffs or other diffs that can be swapped in? Lots of questions I know, but this should be an excelent thing, and really help off the line acceleration, traction but lower top speed (which is fine with me). |
