Hey Craig, my c5 is no longer supported by Audi and you can't get genuine Audi ones anymore. Genuine Audi parts are my go to where possible. My A6 has kyb shocks which are as close to OEM as I could get. I will upgrade them for a proper performance upgraded suspension at some point. As the shocks are ok, but I'm not 100% happy with the ride on the rear now to be honest. Also my old ones were self leveling, you can't get aftermarket self leveling ones which is annoying.
