I've seen a Jeep SRT run a 12.94 stock... That's the quickest I've seen an 8 of any description run without mods. But like I mentioned before, I think my track is about .2 slow. My personal best was a 13.36 @105.19 on Michelin PS2 Summer Tires. The weather was terrible and the track was greasy as hell. Traction was an issue in addition to the 97 degree ambient temp outside. With a nice cool day and a sticky track, I'm fairly certain my car has a 12.99-13.0X in it with a little practice...
