Even the base brakes are pretty good once you upgrade the pads/fluid. I put XP8's and RBF600 in mine and my braking is limited by my tires (RE050A's).
I ended up buying a used touring non-sport because that was the best I could afford at the time. While I do like the Nismo, I don't think I would have bought it even if I could afford it. Actually, if I were to do it all again I'd probably get a 5.0
