Doing an M3 subframe swap on a 6mt n54 e90. Have DCT diff and a couple DCT shafts from e9x M3. Need a shop to cut, shorten, and balance the transmission end of the M3 shaft but so far nobody I've talked to has the equipment for the flex ends or is willing to work on BMW parts. DSS will make me a one piece, but I'd still prefer a more oem type of solution.

So can anybody refer me to a shop that will do custom work on BMW driveshafts?

Thanks,
Sky
