Hey all,

As the title says, looking for a cheap or free working 3.73 open diff for an E30. Want to try out the ratio on my vert without spending a ton of money.

Let me know if you've got anything! PM works or email me at mckay.paul.d AT gmail.com.

dude way to low for your vert, 4.27 was stock, and now way you should go lower then a 4.10, unless your swapping in a 6 cyl, I would not go that low!!!

I dunno... 4.27 to 3.73 is only about a 500rpm difference on the highway. Going to 4.10 would be almost no difference.

But that's why I want to keep the 4.27... if I don't like it I can always change back :)

wait to see how long it takes you to get to highway speed!!!!

Haha, fair enough... I'll see how it goes.
