2016 GTI Autobahn. I’m not following “A3 damper”. What is that? I apologize as I don’t know much about mods, since i’ve been a warranty pussy for a few years.What year is your car? The biggest noise difference for me was the A3 rear subframe damper, it made a bigger difference in cabin noise than tires, although the AS4 are pretty quiet. I changed from stock to AS3+, which are stupidly loud, to AS4 which are a lot quieter, but I couldn't tell you for sure that they're quieter than stock. I had a Mk7 with the sound deadening around the rear tire and the underhood blanket and then this Mk7.5 with neither of those and the A3 damper makes the Mk7.5 seem quieter than the Mk7 ever was. I suppose the ideal would be a Mk7 with the damper.
