that sounds about right. springs could be less..my setup was
sprint springs - 90 shipped
gr2s - 190 shipped
install was about 150, which i regret not trying to do myself 1st
alignment - 75, normal pricing..
i do however regret not doing it right the FIRST time, and not getting camber kits, which i dont think it will kill me right away, but i definitly have negative in the rear, -2. its a 1.5' drop. so in conclusion, get everything at once, get the top brands you want, and you'll love it.
