Best lowering springs for a Mach 1? Car will be on 18s with 305/35/18 & 255/35/18 for the record. I want it as low as possible as the car looks 4x4 right now. Leaning towards the H&R super sport. Any other suggestions? Pics would help. http://www.svtperformance.com/forums/images/attach/jpg_thumb.gif
