I have a 2015 A7 Black Edition on 21" wheels and lowered Sport suspension. I find the ride uncomfortable when driving on poor surface urban roads. I have asked Audi Customer Service if there is anything that can be done about this but they were not interested. I have now found that Koni produce a shock absorber called Special Active, which is a dual rate damper that absorbs severe bumps and pot holes bit retains a firm ride on good surfaces. I am seriously thinking of fitting these and would like to here from anyone who has experience of them.

Sorry Alan, but I don’t have any experience of the Koni shock absorbers you mention. 

 What you are suffering is the product of sports suspension and large dia. wheels. If you consider the larger the wheels, the ‘skinnier’ the tyre profiles have to be, since the final outside diameter of the wheel and tyre has to remain constant. Moving to, or having chosen, smaller diameter wheels means the tyre profile would have been increased and you would have more rubber between you and the road, so a more absorbing ride. 

21 inch wheels must surely be around the maximum diameter wheels available for this car, resulting in a very low tyre profile setup. 

Summary:- The benefit of Koni shock absorbers with your current skinny tyres ?? 

                  Fitting smaller dia. wheels (secondhand?)? Maybe you can roadtest another similar model with this set up. 

Not sure if any of this helps.

Kind regards,

Gareth.
