Sled studs are going to suck on a oval, and are "ok" for drag. I run 70 per tire on mine and spin off the line for a little while. I would suggest getting sled chisels instead of regular studs. I would also suggest running one inch kold kutter studs up front. You kinda gotta choose what type of riding your gunna do, I would do two different sets for drag and playing on the tracks.
