eye standard trophy seats, tbh being stripped it isnt that bad, I had a VTS which i set up for track which was fully stripped - carpet sound proofing the lot ... i havent went as extreme with this yet but its not that noisy. you can hear the road noise a bit more but you can still hold a conversation lol.
Im going to paint the rear in the near future and carpet the floor with some light material just to tidy it up a bit.
