Hi all,

looking for some info on swapping the lsd from a 3.7 to a 4.1. Has anyone done so, and if so what’s the feedback? I see in the US they like to do this swap, or even to a 4.7 from an rx8, but this would of course make 1st pretty much unusable.

Thanks!

The 2.0 5 speed is what I used, alternative get a 1.8 diff and put a LSD in it
