the kit is definitely overkill for most drivers on the street; the SA's are plenty. however, if you like an agreesive ride, with 500 - 600 spring rates, that's when you can take advantage of the compression; but you woudl never move the compression higher than 4 click on the street. Otherwise, you ribs will start shaking
but I agree, the DA kit definitely caters to the "track junky"
