Konigs look much better. I strongly dislike xxr's for they way they look and the way they preform. I know you road course race so I'd highly recommend spending some more money on good wheels. I spent about 2k on a brand new set of Enkeis and I have zero regret. When I'm flying in hot to a corner at 100+mph on the track, I have a piece of mind. Its worth spending the money in the long run too, they better wheels will hold their value much better too.
