Get my car to launch better...

I made multiple passes, but I think it's something static weight transfer (battery in trunk), properly heated tires (install line lock and get good burnout), and less driver error will help with. All I've done to this point is clamp the springs and put longer shocks in. If I start pulling 1.8 60' times, that's shaving about .4 off where I started. It sure is easy to get a car into the 14s, and then the 13s, but I'm realizing you gotta put in some work to have a street car that runs in the 12s.
