Rotella t6 $22/5qts is plenty good for track and daily driving. Its prob the most popular oil for people who track their cars. Really don't need to shell out a lot of money for bandwagon type brands. If you want to get a little fancier, brad penn $6/qt oil is also great, but much harder to find readily. Valvoline vr-1 $9/qt racing is also great too and is available at autozone and such but not really needed unless you run e85.
I don't know how well our cars wear but 3 track days on a single change might be too much. Only way to tell is universal oil analysis.
