What are the rules for NASA touring? Do they restrict the number of damper adjustments or assign more points for more adjustment and that's why you're looking at 1-way instead of the more typical 2 or 3-way dampers used in motorsports?

Anyways, my understanding is that all of the high end suspension manufacturers are licensing the same few sets of patents for their valves, adjusters, etc and have similarly excellent quality control, and the industry is small and specialized enough that its really only a handful of principal engineers or their proteges (e.g. MCS was founded by former Moton and JRZ staff). So the quality between them all is very close, and the thing that will set them apart is how convenient it is for you to work with the engineers to get the product that's right for you based on proximity, communication style, etc.

Cost no object, go with Multimatic. They're dominating the touring car and formula racing world right now.
