I'm planing to attend CSS in 2004 and hopefully go to a few track days. It is time to replace my 3rd set of Michilin Pilot Sport's. I was hoping someone can give me some input about Dunlop 208 GP-A, ZR, and 207 RR. Can anyone tell me the characteristics of each/why would I choose one over the other? Also, the 208 gp only comes in a 180 rear. My bike has a 6" wheel I have been told that a 180 rear on a 6" actually turns in quicker. Is it safe to put a 180 on a wheel made for a 190? Any thoughts on tire width would also be appreciated. If it matters I ride an '01 cbr 929. Thanks
