And don't come with drag radials on that have used at all, they don't work on a Dyno Dynamics. They will slowly spin on a layer of their own goo. You can't tell they are spinning/slipping, but the power readings won't be right. Slicks actually work much better, brand new drag radials might work, but any that have been driven on at all and picked up oil from the ground will give weird power readings.
