You said your Dart runs high 12's. What MPH is that, and what is the 60'? If your high 12 second car is really a high 10 second car with slicks, there could possibly be an issue if the tires are "dead". M/T have been on our car since we started racing it. It's gone a best of 10.82 @ 125MPH. It weighs 3600# with me in it. It has a 4.56 gear and a 4200 RPM stall. We run stock, clamped, leaf springs. I have never had an issue with tire spin. Our best 60-foot is 1.49. We run 29.5x9x15's. I think you'd be very happy with the tires.
