It is flat, but it's because the bottom end is much stronger not because the top is wanting. You don't get the surge you get with a turbo but it's certainly not lacking in speed. It's much more capable, and so the speed does seem to feel a little bit less impressive but I think that makes it more impressive really; it's effortless. I keep getting caught out thinking I should change up soon and then realising I'm just hitting 5000rpm which is when the RS just gets going.As for the wheels, I don't mean black. I don't like black wheels, especially on a black car. My speedlines worked because the rims were polished so it broke it up a bit. The picture is a bit misleading because the wheels are dirty so they look darker. I've seen some US cars with Titanium pack wheels (almost the paint colour) which I'm not 100% on, so if they do go darker it'll be to a BBS titanium finish or maybe even lighter. Not black.
