Everyone wants to lower, I want to lift...

I found a ton of info about springs to lower my GSW but I want to do the opposite. I'd like a little increased ride height, or at least something a little more stiff to prevent sag when the car is loaded down or I have my bike rack on. There's also a lot of info out there about doing this to the JSW but it's my understanding that none of that will work for the GSW. Any input would be greatly appreciated.

Thanks!
