Those of you who have read my previous threads on my handling problems with my 05 MCS with LSD (https://www.northamericanmotoring.com/forums/showthread.php?t=128026 ) might know that i have had my car checked time and again for problems relating to handling (mainly suspension). Finally my suspension specialist who is brilliant, suggested that the problem may be caused by the differential, so i took the car to BMW and they drove it and said that everything was fine, and any problems, if any existed would be due to my "heavily modified" engine (pulley, CAI, MTH, and OBX+oneball). And they refused to check my differential.

So i had the differential checked at a specialist, and he reported completely stuffed LSD clutches, metal filings in the oil, a chunk missing from a metal plate somewhere (i can't remember), and some pin being broken! So after 2 years of searching, there is some light at the end of the tunnel. I'm getting a Quaife ATB installed, and i hope that my car will start to handle again (will post an update).

This is provided for anyone who might experience the same handling problems as I, CHECK THAT DAMN DIFF!
