I will be selling my M6 Wiles 4” alum driveshaft, it was just back from Wiles for chdvk out before the thanksgiving entire driveline replacement including transmission, runs smoother then any 1 piece slum driveshaft I have ever been in. A M6 drive shaft spins about 33% faster than a A8 driveshaft which makes them definitely more hit and miss NVH wise. PM me if any interest in it, $900 shipped, has only about 150 miles on it.
