Yeah, $320 for SVT shocks and Ford Racing springs and it gives you a 1.5" drop. The SVT shocks are just fine for the FRPP springs as they have more dampening than stock. Steve will know exactly what you want.
The advantages of the BSD are exactly what you stated plus you add 1qt of oil which allows your engine to run a little cooler.
