Spark ramp plays a huge part in getting the launch down with these cars, especially in first gear. I've done several other things since then and I think they all contribute to where we are now. Things like solid cradle and diff bushings, removing or disconnecting the front sway bar, and getting the air pressure right. With the 17's I had the best luck when the track could hold 18 psi, but would usually start at 15.5 and go up if I could.
