Also very interested in this. I have JRZ Pro coilovers to install, I received the front ones, awaiting the rears. Ben recommended and included 300 lb springs on my fronts (engine is the same as OP, L33 5.3L). The roads around here are incredibly poor...
There's alot more to ride quality then just overall spring rates. It does play a big role but If you put 300 lb springs in 2 240s with 2 different types of dampers you can have completely different ride quality and feel. It all has to be matched to get your desired results.
