i had a 1"-1.25" drop for 2-3 washers, and it wasnt perfect, will be using 4-6 per side later to get it to 0 degrees.
AGAIN it depends on the thickness of the washers. I measured mine and told you the thickness.
btw, i have a set of front control arms off a 94 ex if you want to get the ball joints but dont want to press your current ones off. They came w/ the boots busted so replacing the ball joint w/ camber adjustable ones would work perfectly.
