Seeing that SS springs have been used on the fastest stock/super stock eliminator cars in the country running 9-10 second elapsed times @ 130-150 mph would mean that these systems are working great on cars putting over 700 horses to the ground and have been doing so for around 40 years, it is really hard to improve upon that type of performance.
Also, if your super stock spring set up is working properly, you don't need a pinion snubber. The whole principle of the SS spring is that it creates body seperation. So if the springs are working properly, the body levers itself up, rendering the snubber ineffective. Snubbers are only necessary on street cars using stock style spring packs that may also see racing type launches.
The quad shock set up is sold as the Ground Pounder by Just Suspension. It is actually a second set of shocks that mount over and almost parallel to the leaf spring. The whole idea is that is absorbs and eliminates the wrap up of the springs. The reality is that it is a band aid fix for a problem of weak springs or incorrect spring rates and all it is doing is dampening the movement and it is not eliminating it. It is, after all, a "shock absorber" that is just mounted in a different axis. Just like regularly mounted shocks don't stop movement but dampen them, so do the quad shock addition. Unless you have your combo together and know you have a spring problem, there really is no need to add extra parts, weight, and cost to an already decent system. Get better springs and fix the problem for good.
