Coilovers

The coilovers I want to get have always been a really tough choice, but I think ive decided on the powered by max pros, my only concern is if the will go low enough. I want fitment like the white 240sx silvia i posted early with the 17x9 and 17x9.5 ssr's, I will be running the same size wheel. If any one has experience, advice or a link that could help me with this problem pleaseeee post it in the coments.
