how much was the LSD?
LSDs are available for most all models. Make sure the gearing matches your vehicle, though. VIN research will determine your vehicle's diff gear ratio. Depending upon the transmission, for example, the 335i Automatic Transmissions have a higher (3.46) gearing than the 6MT (3.08), so you need to match your engine's gearing.
Check out my links...I added web sites that have prices.
Wavetrac: $1199-1295 + rings, etc. + tax/shipping
Quaife: $1305-1400 + tax/shipping
The above are for the diff swaps. Complete pumpkins are different, up to $3K and above...
