LSD Woes... please help

[slowlysideways]

I'm on the lookout for an LSD'd rear diff for my 325i.

The car is a road going drift/ track car but rarely driven on the roads.

So I'm after a decent diff.

Should I hold out for a 3.91? or should I consider a 3.73 or 3.64?

Can anyone explain in laymans terms the pro's and con's of each please?


Been offered a "silent" 3.64 for £250 - is this worth it?


I'm a bit of a rush, as need it asap before our trackday at the end of the month.

Many thanks all

3.91 is what you want then as it's higher geared, easier to lock for drifting/better acceleration on track.

Thats cleared that up then.

I have cash waiting for a 3.91 to come along, need it asap so I can get it fitted!
