I spoke with Roger from Speedtech, (thanks for the help!), and he stated that they sell the track time package with 450/220# coils. (these rates are assuming an LS2 or LS3 Block) Unless I'm missing something, wouldn't the Speedtech system ride nearly as rough as the originally tested TCI Car given the 450# rates?
Thanks in advance for you input.

The ride quality depends on the motion ratio and the spring rate. In simple terms, if the spring is farther out towards the ball joint, it has a higher motion ratio and the spring is more effective. If the same spring is moved closer to the bushings of the control arm, the motion ratio is decreased and so is the spring effectiveness and the ride will get softer.
What will effect the ride quality is the final wheel rate. This is determined based on the spring rate and the motion ratio.
For the rear suspension, as far as I know, both set ups have springs mounted directly to the axle housing and therefore have a 1:1 motion ratio, so the springs are a direct comparison.
Shocks are also a huge part of ride quality, and should not be overlooked. Adjustables are a major help as you can tune them down for the street.
Hope that helped
