Torsion bars and lower control arm set-up

That wasn't actually the factory spec though if you look at the measurements. That might have been something they did at the dealer to sell the car, or someone screwed up.

Oddly enough, the AAR and T/A cars that were actually raced in the TransAm series were higher than the factory spec to clear the tires they were running for the competition.
nope, that was the way they came. They also had special rear springs, which contributed to the rake. I'm pretty sure the rear springs was for clearance on the side exit exhaust, which came in pieces in the trunk, because it wasn't legal in some states
And no, the dealer never touched my car.
