MFactory LSD Differential

TunafishE93 · 02-12-2020, 04:50 PM

I opened a ticket for MFactory but they just deleted it without any comment. Not good when asking about a thousand dollar part and one reason was looking into them was customer service.

Anyways maybe someone here can answer my question. I am looking at their diff that is >3.15 gear ratio.. I might be interested in going to a 3.08, does this diff except that or is there another part number that will? Thanks.

I have a M Factory LSD and have been very happy with their service. Maybe you should try calling them.

For what it’s worth I wouldn’t bother spending any money on changing from a 3.15 to a 3.08. That’s just over a 2% difference it’s not really meaningful and I don’t even see the point of that. At a speed you are hitting 4000rpms now you wouldn’t even be lowering the RPMS by 100.

There was other gear ratios I was considering .. All lower than 3.15 so question is still there.
