I think my DRC might be failing*, does anyone 1) still own a C5 RS6, and 2) if so, is anyone running aftermarket suspension?
I most recently read an article about a tuner shop in the UK retrofitting the Bilstein PSS9s on their C5 RS6 (pesky DRC), and they seem to like it, but I am looking for real world consumer opinions.
* Poor excuse to spend more money on useless car parts...
