3.9 Diff Gears

[Jesterarts]

Hey,

Im looking to get a LSD diff with 3.9 gears in it...

My question is what would my car's rpm be sitting on at 100km?

atm its about 2100 in 5th @ 100kmph...

ALso where is a good place to get a LSD and diff gears around melb preferably on the mornington penninsula?

depends what ratio you have now...is it 3.07?
if it is then you'd be on about 2600rpm with 3.9's. (2667.75...to be use the exact figure i got, lol)
