I bought a RS6 wheel, but don't have DSG. For me, having the paddles only reminded me that I should have specced DSG, doh! I looked at removing the paddles, but IMO the "holes" would be too big and "messy".
I've seen and held the TT-RS in person and I actually quite like the perforation, matched the perforated side bolsters in my buckets. I still plan on getting the TT-RS wheel, but prices have gone up.
When I was looking to buy, I called Audi direct and they were looking to charge more than Trade Part Specialists for some bizarre reason. They do pop up on ebay and ebay.de, but sometimes bidding gets out of hand. One day though, but it might just be attached to the TT itself when I finally get my hands on it.
