If you put commodore wagon rear shocks in cut rear springs will stay perfectly captive, technically it's illegal to cut springs, but anyone who's played with KE's know if you have commo shocks it's as safe as factory with full height springs.
Rear Kings are fine, but the fronts are a bit soft IMO, unless they're custom ordered. They're low height standard weight spring.
$300 Otomoto weld on coilover kit, is the path I'm going on my corona struts, can be had in any spring weight.
What you do just depends on if your looking for looks, or handling I guess.
