Wheel Hop

Dig that, I'm Assuming that's why our cars actually " lift" , or appear to in in the rear? Due to the torsion bars?
No. That due to axle wrap. As the car accelerates, the pinion gear tries to climb the ring gear. Since it cannot, the axle housing rotates the opposite direction of the drive axles causing the leaf springs to push UP on the car while pushing DOWN on the housing ans tires, planting the tires into the pavement. This is much more pronounced in cars with race bred rear suspensions like with SS springs or Cal Tracs. You can really see the body lift during a hard launch. The Mopar leaf spring rear suspension is about the best there is at taking advantage of this, IMO.
