The new finalized rules package was released this afternoon, I didn't know the plates are finally done after Daytona in favor of spacers depending on track length, 750 hp at road and short tracks with a 1.17" spacer and 500 hp at tracks over 1 mile with a .922" spacer. Some aero mods as well including ducting at the 1 mile plus tracks.
