I've only ran it a few times on street tires, 4 to be exact. It really spins, a lot. You have to get the perfect balance of spin. First 2 runs were awful, all spin. Then went home b/c the clutch was brand new and I kinda slipped it on the second run. Second time I went did a 13.4, then a 13.3. Can't launch it, it will lose traction if you let it go at 2500-3000 completely. So I'm rolling off the line, getting a 2.2 60', and a 107 mph. so It definitely has 12's in it,just have to have a little more seat time. Slicks for sure 12's would be easy. I beat the 2002 camaro SS w/ bolt ons and a new g8 gt.
