I would highly doubt it, the hotchkis kit is ENGINEERED to make your r/t handle the best. So dropping it lower will probly make it not handle as well...there slogan says it best "horsepower for your suspension" i'm sure hotchkis would have designed another model of the kit that was lower if the dynamics and physics of the complete setup would be the same...that's why they only provide the 2/3 drop.
