Your going to have to submit a request to use aftermarket non adjustable struts like tokico hp's and probably eibach pro-kit springs will be the stiffest aftermarket springs. You will have to do some research to find what threaded shock adjusters will fit the strut you may even have to have them made. Basically ride height and spring preload are adjustable but adjustible struts are out. And as for camber plates real racers dont use the adjustable kind your thinking of as they can slip under hard cornering. You will have to make fixed plates at lets say 2-5 degrees of camber.
