This is from a few weeks ago at the KW Tech Day. Same day I ran a 1:55.1 on A052's, but this is from the morning on a fresh set of Nexen SUR4G's, 275/35/18 all around. Definitely have to work a lot harder to be quick on these tires vs the Yokohama's, but they're really impressive for the money, and they last.
