experiences (with my car and several others that people were silly enough to let me drive), it seems the stock springs and shocks/struts work best. "We" set the front up on touring and the back on sport to allow the front end to lift some, and transfer weight. That set up seems to allow for mid 1.5s to mid 1.6 60' on a variety of manual cars. The autos w/o nitrous range from mid 1.6 to 1.8 60', depending on the stall of the converter and turbo type. Add some n2o and as you've seen with Greg's car, 1.46 on stock suspension. A good alignment on both front and rear is critical to allow a good footprint on the rear tires, and to make sure the fronts aren't being "dragged' down the track. The alignment for drag racing isn't particularly road racing friendly. Hope that helps some, Mark
