Hello all, I just bought a new 07 GT manual tranny. It's my third stang but the first I've owned since my 93 5.0 coupe. I just found out that the ring gear is a 311. I have never heard of that and the parts guy told me it was a little uncommon. Has anyone heard of this? Also I am looking for the cheapest performance upgrades to get me started.
