Update from the weekend. Started off at 20 lbs. First few runs just blew the tires away at the starting line, even after decent burnouts. talked to everyone at the track I could find running drag radials (but not Nittos). They all said they were running 15-16 lbs. Lowered them to 18 and then down to 15. I think what finally happened was that I burned through the outer layer and they started to get stickier. I also think lowering the air pressure that much was a mistake. I was getting weird wheel hop like movement out of the rear suspension (super stock springs) that I never had with the slicks. One other thing that worries me. I marked the tires at the valve stem, and by the end of the day the drivers side tire had rotated 180 degrees on the rim. The passenger side moved about 6 inches.
