Need Differential Rebuild Recommendations

[///M3RIC]

Is this Pedro the best source for R&P? I’m considering either 3.91 or 3.85. What’s the going rate for those?

Don't think so. A 3.91 was $1200 the last time I checked. You can get a 3.85 from a manual E9X M3 - I think about $400 was the market price.

+1 to Pedro.

I was recommended by him through a track friend and I’ve been running his ZF diff since February. I’ve used it through multiple track days already and it’s a great upgrade.

Where can I find a 3.85 for $400? Everywhere I’ve looked has them for ~ $1,000

M3Post should have some used. A lot of those guys will swap in a 4.10 or a 4.44.
