Just pulled this thread up and realized it was mine from a few years ago. The ET streets are still in great shape, but they haven't seen many street miles, as I drive on street tires for the most part and just put the ET Streets on for track days. To further skew the results, the car has seen less than 20 passes in the past two years. Now that I think about it, I might throw them on just to go with the "strip" part of the Street / Strip look for a while, as they're mounted on black steelies (the car now rides on black spoked torque thrust style wheels).
Edit: Oh, and by the way, the car dead-hooks with them (255/60's) and 60's @ 1.63.
