BMW 318i REAR DIFF

Lubos246 · 04-02-2021, 10:41 AM

Hi guys

I have a E90 318i N46 manual

I need a new rear diff I don’t mind going a higher ratio I am 95% of the time driving in the city.

So my question is what alternative ratio can I go for I think the one I have now is 3.38 according to realoem website.

Could someone give me more info as there are a lot of variants and I have no clue what to buy

Thanks

No idea what the rear diff in your car looks like or what ratio your transmission has but I'd throw a 3.73 in there. Probably a direct swap as they're both rwd differentials. What rpm are you at on the top gear at 100km
