Mate, I just got a set of 18's and went Falken 512's no complaints from me yet, much quieter than the 17's but a little less traction in a straight line. I think that is more down to the fact that 40psi was put in the tyres, compared to the mid 30s in the 17s. I really just wanted to steer clear of nankangs as I have not hard a good thing about them really. The Falken 326 are a low level Falken and you can do better for not much more money IMO.
