Are these £450 17'' wheels any good for my NC?

I have the RC32 wheels in anthracite (aka dark grey), this link to a post on ride height shows them on the car in the very first post.

I really like them, and they were cheaper than refurbing the original wheels (after selling the original set). I bought them with Asym5 fitted and balanced for £660 from pneus online. Good quality tuv approved wheels for the same price as Chinese no name cr@p.
