What is needed to build a 7 second (1/8th) street car

Very good time out of the dart. I was thinking about pulling the front sway bar and installing softer tortion bars for better weight transfer on the duster. It does spin some off the line (not alot, but any and im loosing momentam) and Im pretty sure that is what is killing me. I have had the car for 3 years. Finally decided to see what she would do at the track and Im thinking it should deff. be quicker than it is
