Keep the questions coming!!! And chime in what you would be willing to pay for an LSD!
I looked at Tischer and a stock 335i differential (part no. 33107571187) can be had for $1300 (MSRP is ~$1600)
A stock M3 differential (part no. 33102283006) can be had for $2150 (MSRP is ~$1800).
So a BMW Performance Differential should cost somewhere in between, let's say $1800
