C6 S6 is not DRC, regular sprung suspension. In fact that's one of the odd things in a way - the C6 A6 can be had with air suspension (so it fits the chassis), the S8 has air suspension (so it can be made a bit sporty) but the S6 is sprung. <shrug>
No sure the S6 is really sprung Chris - I think they left the suspension out. There must be a choice of some after market options for the S6 suspension?
Maserati GranTurismo GTS Auto, S3 Sportback, TT2 3.2 Roadster, Disco3 for the heavy stuff.
