Is your car a daily driver? If it is I would not go more than an Inch and a half. Your car will ride so horribly. If you do, put strut tower braces on the front and rear watch the profile of you tires, thinner, equals hard ride, thicker, equals softer ride. Work with the math on this one, you still want travel with the shocks. Coil overs would be the most optimum way to enjoy the ride and have superb handling.
