I think the Dunlops were the control tyre last year for the Vtec Challenge, I seem to remember negative reviews, but this was over a 15 minute race, not a trackday, maybe try the VTC forum or HOT for accurate feedback. TGM race with the Dunlops, and rate them over an hours race (17").
I spoke to a couple of racers last year on the FZ-201, said they were good in the warm/hot weather but on a cool day really struggled to get heat into them and found them lacking for grip, again a race application.
I recommend the Kumho V70A, not quite the grip of the 48's but better than the 888 for me anyway, its what I raced with last year, 40 minutes, (hard front, medium rear), although I still have some 48's left the cost for new even in 15" is staggering.
Even after reviews its good to try them yourself as your car/driving may suit better, maybe try the 888 in hard?
