I figure if anyone knows the facts on C6 suspension set-up I would find it here.
Looking to change out base suspension ie: sway bars, and shocks. Drive the car on the street as well as track days, etc and don't want to loose all comfort. However after going from 05 with z51 to 06 with base suspension I am now adding PS2's, Blistien sports, and need some advice as to what sway bars will mount-up (06 A6 base) and what others have changed-out to? Also, any other other components that will increase corner performance (besides coil overs)?

Thanks for any and all help.
