Current issue of GRM has a side by side test of the new Michelin Sport Cup 4 and the Continental Extreme Contact Sport in dry (Harris Hill) and wet (TWS) Good article, SP 4 still has a slight edge in dry, Conti in the wet. Bottom line was Conti improved dry performance up to the level of the previous Pilot Super Sport and retained wet performance advantage and priced about $50 less per tire. Since I have track only tires think i'm going with the Continental's to replace P Zero's for daily street use.
