i was under the impresion that our cars have a 4.10 diff stock, also a short throw shifter does not improve 0-60 times in my opinion, maybe if you suck at shifting it does. and as for it beating an 325i, i have always seen our car kick ass off the line compared to a 325 maybe due to the gearing in our cars, or maybe im just really good at launching:p . im gonna go with the gearing.....
If I'm not mistaken, a lot if not most of them may have came with the 4.10 yes, but not the 4.10 LSD,, it was an open 4.10,,, Something grabs the back of my mind saying 3.73's? or something like that was available too?
