my bro used toyo, pirelli, and currently yoko.. he said toyo finishes a lot faster.. dunno y.. korean brand mayb? :P his pirelli lasted for around 2 yrs.. pirelli isnt that expensive... if you dont look at their top of the range products.. Pirelli's P6000 or P7 (4got) cost around the same as the yoko's A drive R1.. hes using A drive R1 now coz.. its a little cheaper. im gonna go and get some quotes for the A drive/S drive tomorrow...
