False. The Hyper has about 20% more spring frequency than the AE does using four yellow front springs (way stiffer than kit) and nobody complains about the Hyper being down on grip. They can also get away with 17mm of ride height as long as they backside all the jumps.

False. Truck has poor air control because of the spring mismatch (rear rates are radically softer than fronts), causing the truck to launch wierd if you have to jump on the gas. If you increase rear spring rate, be aware you'll need to increase damping to match the spring with the shock.
