I just put those on my Z. I have put a lil' ove 1000 miles on them so far. I have nothing but good things to say about them. Also been in the rain 3 times. The last time could be classes as a torrential downpour. No slip and all grip even at highway speeds. On the dry they ride great and corner better. Also I got an email from sportbiketrackgear.com that they are rolling their prices back to something like 2 years ago prices. That's through August I believe.
