Shock questions

No no no no no. You do not want the rear to squat. Squatting takes weight off the rear tires. You do want rise- that puts more weight on the tires for traction.

The CalTracs need a loose front end for them to really work well. The Vikings are double adjustable so you could loosen them up when you want to launch, and then go back to stiffer for street driving. Just spend the money.
