Well it's been almost 10K with the Pilot Sports now. Got to hit a major canyon with them a few weeks ago! Grrrrrrrrreat! Took some 20mph corners at 55. Pushed and pushed and pushed. Finally got the car to go into just a bit of understeer at about 56 through a tight pin. Definetly grunting before the car did. Even so, where they shine the most is in the rain. Poured all day today in Modesto. The car still stuck like glue. The original tires would have given up way before these. If your thinking about Pilot Sports and wondering if there worth the extra money? they are. Oh ya, so far the feathering hasent returned and I show no signs of ware. Yes!
