I've only run them on the street since installation. No track yet, but they, imo, provide very good traction from dead stop, and that is on SHR heads and cam, from both a peddle stomp and a 1000rpm brake. Very good in turns as well. Been running them at 36 psi cold. Pics tell the story on appearance. Oh yes, and the White and Orange GT500 Shelby (1 of 128 in that color) I put 1.5-2 cars on from a dead stop to 95 mph Sunday on my way over to Eddie's to get my air/fuel leveled out thought they hooked pretty well. :yahoo: Went to track last weekend and they did well. Very little if any spin. 60 ft times were consistently low 1.80s. Best et was 12.71. Terrible mugginess at 77 degrees temp. Everyone was pretty slow and boggy that night, but tires did fine.
Well I just ordered the Michelin Latitude PS2s in the same size WOW they are not cheap almost double what I paid for these but I think they are much better they are on my Cayenne and it drives smooth.
That was one of my factors - about $1050 delivered for 5 of the Vreds. Hard to pass up, but it sounds like you got a really good set of tires.
