Dunlop's there is NOT a better race tire made!
1st off there 100% real rubber were as most the rest are synthetic rubber compounds, they have great feed back and feel, you can tell what the tire is about to do, unlike Michelin slicks that have great traction until they Don't! and feel vague due to the soft carcass of the tire.
PS> you need tire warmers with Dunlop's or ANY Ntec they make. if you don't heat them you will damage the tire due to the VERY low PSI they need
here is my set after 2 hard days of testing and over 340 miles on the track. the Dots were gone the start of day 2, and the tires never let go or got grease!
