Get rid of the street tires! Drag radials will really help, regular slicks would help more.
Soften the front, get some 90/10 shocks they are fairly inexpensive. Loosen the control arm bolts so the bushings pivot instead of reacting on the rubber. Disconnect the front sway bar at the track.
You are going to have to play with the launch, you will not be able to tell anything until you get a sticky tire. With the tire you have I probably would not spray until it starts to recover from the 1-2 shift.
I know I seem to be stressing tire a lot, But that is the next step before any real suspension tuning. I leave off of a trans brake. I am on the two step at 3400 when I leave the converter spikes to 5500 and I shift at 7000. That is on a 28/10.5 MT slick
