WTB: 3.91 Diff

grantmax · 10-08-2022, 02:10 AM

Hi,

I am looking for a 3.91 diff for my 2004 M3 coupe. I’m aware of Diffsonline but have heard some not-so-good things as of late. Plus, a broken-in unit offers the benefit of immediate regular driving.

Please PM me if you have a new or used 3.91 in good condition.

Thanks!
