12.6 is awesome man. Wait till you get hooked. My GF says it feels like a rocketship. I love my 4.10's. They win the race for me now. Second gear pulls me out soooo nice. Check this from last night. I did however see a 04 Z06 completely destroy his 2nd gear. It looked like chicken noodle soup on the track with all the metal bits and tranny fluid.
