Hi all . i've been offered a fairly cheap 325i auto 4dr with an lsd .
I'm just wondering does any one know off hand what ratio it would be ?



thanks for looking

[daimlerman]

3.64
3.73
3.91

Could be any of the above,they may still be a readable tag on the diff...

normally 3.46

Thanks very much lads . i googled it and got my hopes up when i got onto a US site where it was suggested that it would be a medium case 4.1
