My times dropped approx 1.5 seconds from the KU36 to R888 with the car in similar trim. The R888s seem more affected by a cold day than the road spec KU36. The R888s also required a bit more aggresive camber than road spec tyres (I have - 2.2 on the front to get initial turn-in and may go for more).
I chose the R888s on the basis of price for reasonable performance and hopefully a reasonable life as they were not much more expensive than the KU36s or Federal performance road tyres. I also drive on them to the track. The Bridgestone RE55, Dunlop D03, Yokohama 50 or Kumho V70A would all be quicker if you wanted to spend a little more.
I ran the Kumho's V70A on Fanta and was very happy with them. I managed consistent 1.10s on V70As compared to a best of 1.09.25 on full Dunlop slicks.
I have not tried the Bridgestones, but Bryan's times on them show they work well.
