I'm guessing the allroad lads would just code the car to a normal a6, if there was a d3 without adaptive suspension from factory I'd try and go from there, it's my own opinion obviously but why coilovers? If you want stance people use air as its best of all worlds, if you want handling then coilovers, but the a8 even though it does handle remarkably well, will never be a track car.
