They aren't drag radials, they are street tires. For the first launch, I think I was at 4,000 rpms, the second was I belive 4500, and the last 2 were 5800-6300 about. I have ground control coilovers and kyb agx's. Im not exactly sure how much Im lowered, about 2 inches probably. The reaction times I felt were irrelevant since the clock didnt start at the green light, it started when your tires passed the gate. But if it means anything to you, my r/t's were anywhere from around .298 and a lil higher. Thanks for the input, more is very welcome.
