I personally would go with coil-overs up front with adjustable struts and something like a FMS B, Mach 1, or Bullitt rear spring. This is a very popular combo choice for a reason. I run a similar combo on my car with 14" 175lb springs set just a little lower than stock ride height (this helps to store a good bit of energy) and bullitt springs out back with strange adjustable shocks/struts all around.
