Just buying an m60 converted e30 and the guy reckons its got 'whatever diff came in a 325 se' fitted, so my guess is a 3.91.
Now he seems to think its geared a bit short, i have no idea!
Its an m60b40 with a 6 speed box fitted. Anyone know what would be a good diff? Ideally i'd like it geared to about 170-175mph at the redline in 6th.
Cheers

i run a 3.64 in mine which is out of a e30 325 im sure, Its great for 3rd/4th drifting but shit for road, Ive got a 2.91 i was planning to use on the road,
Can i ask why you would want to do that speed in a car thats set for a track? lol

Jonsku, thank you, perfect.
Darrenr, i'm at the 'ring a lot, my old 325 i could pull to 140 on the fastest part, with a v8 i'm fully expecting to hit approx 160 on the same part but i dont want that to be the redline

Next ring trip will be 17th to 21st of may but thats for the 24 hour race, no tourist laps.
Next trip after that will be 1st to 4th of august. Feel free to come and have a look at my conversion, but i didn't do any of it lol, plus its semi-dismantled too!!
