Easy for you to say, John.
After 4 years of racing carpet I just today put on .020 springs and a .075 t-bar. I also replaced the 1 year old square diff balls I had, so now I have diff action. So now instead of a bone-stock-asphalt setup-neglected beater 12L3, I'll have a mostly stock-carpet setup-just got some wrenching love 12L3.
See you soon
I have a bag of tires for you.
