My Q60 is at the dealer waiting for a new DCU and I was loaned a Q50S awd. Even in sport plus mode on the Dunlop runflats the ride seems to be noticeably more compliant/comfortable than in my Q60. Does anyone know the differences between the suspension tunes of the Q60 Luxe/Premium RWD as compared to a Q50 Sport AWD? I'm wondering if the suspension tunes are truly that different or if my shocks might be shot? I did not notice any oil leaks on the shocks when I swapped my winter tires to my summer tires last month.
