I used to run R888's on my GT3 and that did over 200miles of Snetterton at about mid 1.20's and 2000 road miles before I swapped wheels.

I dont know why you are comparing R888 and Paradas though, as the Yokohama equivalent to R888 is Ao48 which are a BRILLIANT tyre and are available in 2 compounds, of which the harder one is slightly harder than the Toyo's and last ages. I use them on the front of the Drift car all the time, and on the rear for track days and they last really well. A friend of mine who competes in Time Attack in his 500bhp Scoob used them for 2 trackdays, quite a few road miles (2000+), and drove them to a trip to the Nurburgring (including sub 9minute laps) and they were still going strong and could have probably done the same again !!
