It will work with poly in the housing but run the watts in one of it`s 3 highest settings to prevent RC conflict. As far as running the watts with beefy upper arms AND hard bushings or bearings in the axle housing, just don`t do it. It`s dumb. 
PS. Lowering the rear RC with the watts actually requires a big increase in rear spring or swaybar rate. That`s one reason we designed the watts and Spohn adj. rate rear bar to work together. I still prefer to run the watts relatively high, 16" or so. We haven`t seen any measurable gains from lowering it much more and it requires an uncomfortable increase in spring rate and sway bar rate to keep the car neutral. Been there,done that.  Mark SC&C |
Hey Marc, great info. And I hate to hijack this thread. But I have a couple questions. The pivot point for the propeller. Can you steer me to a good description of a baseline to start with to weld it in. I have read up on roll center and I "kinda" get it, still kinda baffling. I gotta try and wrap my mind around that issue.
What I have is a AME 4-link, poly bushed
Air Ride tech shockwaves. The car is a light 62 nova. Im just trying to determine the correct location, height wise to mount the adjustable plate for the propeller. I have as much room up and down that I need. Im just lost as to where a good starting point would be. Centered on the axle housing with equal amounts of adjustability up or down? A lil lower, a lil higher??
And the spring rate issue you talked about? With these air springs Im kinda stuck. I think they are fairy progressive in spring rate, being an air spring.
Dont mean to be a pest, or to hijack this post (sorry). Any help would be gratefully appreciated. Thanks... JR
