Motons on a F355

Thinking of putting triple adjustable Moton Shocks on my F355. I have P Corza tires on Challenge wheels. I would like to lower it. The car always feels light above 120mph . I know some of this is the power steering, but would lowering the car help this? I had triple adjustables on my Viper and that car road great and really handled. I also have alot of lift on the front end in hard acceleration. Would stiffer springs help with the weight transfer. I would like to get the best handling for street driving without hurting the ride. Any ideas including alignment specs. I am not worried about tire wear.
