You missed the point.
The coil-over fanboys do just like you did...reach for the most expensive stuff to try and show that the price difference isn't so much.
Your comparison is flawed.
The factory strut rods are fine. The upper control arms are fine. You can get more caster with the offset bushings OR tubular UCAs from sources FAR cheaper than Hotchkis. You can get sway bars from sources FAR cheaper than Hotchkis. The parts in the "Front end kit" you list would remain unused in your scenario...UCA bushings, strut rod bushings, sway bar link kit.
Besides, these A-body cars are the entry level models, the Mopars that appeal often times to a budget minded enthusiast. Your beloved coil-over setup is an All In proposition while a guy that is tight on cash can improve the torsion bar setup a little at a time as money allows.
You will not go any faster on a road course with your coil-over setup. Spending $5000 to get better header clearance is like blowing $10,000 at a casino just to get the free drinks and a night in their hotel on the comp.
