Sulli,
Yes, given a torque tube, lowering would create havoc with the drivetrain geometry by use of mono leafs.
Following this thread? Open driveshaft will lead you to the lowering ability if you are dead set on it.
AFA "The ride and handling will suck.." I have 90k miles on a stock suspension dd/only vehicle, although not a sports car, very comfortable ride with very good handling courtesy of front steering damper, front sway bar, all zerks greased on schedule, good king pins, radial tires, etc. I can't imagine for instance driving at the speeds and distance I travel with bias plys (just for the period correct skinny tire look).
In addition, driving 'at truck height' has made me a better driver just because I can see OVER all those low identical cars on the road nowadays.
Regards,
