Greg,
The set of camber plates for my charger are installed underneath the towers so it is possible. They are a universal kit since for some reason no one made a kit for my car but it made more sense to provide additional bearing area during compression rather than relying on bolt tension.
Also, it may be important to mention that the reports on the neons suggest it doesn't respond well to excessive lowering. Supposedly the geometry doesn't respond well and there is not a lot to be done that is IT legal. That is just secondhand information though so there are some others with first hand development experience that can hopefully chime in. What about it Chris, any hints?
Of course with the right spring choice you should be able to allow for however you decide to install the plates.
