Hope somebody can help. I am looking for a diff with a ratio lower than 3.14:1 ideally around 2.8:1. This is not for use in a BMW, but within a racecar. I have been told that there maybe something suitable. Ideally an LSD.
Excuse my ignorance, but I know next to nothing about the BMW marque
I think the "is" or sport models have a smaller differential. They come with a close ratio gearbox with a 1 - 1 final drive ratio in the transmission. Of course I dont know if this is true, its just something I read somewhere.
