I'm thinking 1000 lbs/in might be better, then it should only sag an inch or so.
I am going to give GC a call.

Remember, it's not just lbs, it's "lbs per inch". If the 450lb/in spring is compressed 3", then it is holding a load of 1350lbs. Switch to 1000lb/in with the same length and your spring will only be compressed 1.35".
Note, I said spring, and wasn't referring to ride height. Your suspension acts as a lever to increase the load at the spring, I'd guess by about 50% on the rear (I'd have to measure to determine exactly). So, 950lbs at the wheel is probably ~1400lbs at the spring.
Increasing your spring rate means your suspension will be underdamped as well, unless you replace the shock too. Going to a taller spring with a similar spring rate may be a better option if you can.
