Differential choices in an m50???

[makman]

Hey, ive bought a 3.72 ratio Differential (i think thats the number, forgive me if im wrong) which ive been told is a LSD.. both outputs turn the same direction but its not locking up, so its probably worn and in need of a rebuild, but this diff teamed up with my e36 box and m50 lump, its Horrendous on the motorway!

Whats the best ratio differential to keep my car motorway friendly with nice and low revs? its going to be turbo charged later this year also so i dont mind it been abit dormant until then?

2.93, 3.07, 3.15 etc

find yourself an e30 m3 lsd, that will be the ticket

[makman]

it will cost a fortune though! aha, my plans are to get a lower ratio one then weld it to be honest, then rebuild my 3.72, sell that and with the money buy a belter (m3) ....need my car on the road at all times though, young women cant pick there selfs up can they... haha

So your going to make a rare low ratio diff worthless to save money

[e30-EVN]

lol i suppose they cant mate

ive seen them go for between 350-400 quid

[makman]

well im sure I can pick up a lower ratio open diff up for not much no?? and yeah thats what ive seen them going for too!
