I am looking to sell Dinan 3.62 LSD (only for DCT cars). It will work on all E9X as far as I know. It is the best mod you can get for your car ... It drives so much better/different and 3.62 Final Drive is the perfect match for you DCT. I believe due to its popularity Dinan just recently raised their price on 3.62 FD.
You can find more info here - Dinan 3.63 LSD
It was installed a few month ago at Dinan facility in Morgan Hill and tested personally by Steve Dinan.
Retail price - Dinan 3.62 LSD D773-0902 - $2999.00 + core
BMW Differential Cover 33112283010 - $397.40
If it is installed at Dinan facility or by authorized Dinan dealer I believe the warranty can be transfered to the new owner.
I would prefer to sell it locally.
New Price: $1600 + core
There is nothing wrong with it, I am just getting a new car.
