M135i LSD in Auto M140i

Post by CharlesM505 » Tue Feb 20, 2018 3:52 pm

I am struggling to find out if an LSD from a auto M135i (part no 33108659987) would fit into an M140i auto. I spoke with Cotsworld who said part 33108659989 is for an auto, but if you have a manual M140i then part 987 would fit.

Does anyone have any experience swapping an LSD from a M135i to M140i? Or does anyone know the differences in the diff/any reason as to why it would not fit?

Thank You

Wrong ratio.

M135i Man-box & Slush-box, plus M140i Man-box are all the same at 3.08

M140i slusher uses 2.81
Silver F21 M135i - ManBox - HK - Adaptive + Eibach Pro's - BBS CH-R's - BMWP Drexler LSD - M4 LCA's
