First, what do all the tubes on the axle have to do with a frame mounted watts link? The only thing that connects to the axle are the links?

Second, are you telling me this design was accomplished through trial and error? Shouldn't it have been designed by engineering principles.

It just seems like there is a bunch of unsprung weight on that axle.

Hmmm...my background...Internet poster. What is the background of Mark. I would assume he is a suspension engineer or has a great deal of race experience. Maybe we should be concerned about his background.

The question was intentionally open ended. I want justification for all the tubing on the rear axle. I am not making it, I am buying it, so I want to have some level of confidence that I am buying something from a qualified company.

OK, so you don’t like my vague questions. So, I will ask engineering questions. Then I can do the math to see if this is something I need.

1. Was this designed for a range of ride heights? If so, what is the range and the Jounce and Rebound levels for each ride height.
2. It looks like the tubes for the watts link hang below the diff. How far below, and what is the ground clearance at curb and full jounce?
3. What is the rear roll steer % at each curb height?
4. What is the range of anti squat and anti lift %?
5. What CG height are you assuming?
6. I know you need to remove a portion of the tunnel, do you need to remove any of the floor or trunk to accommodate the rear mount for the three link. It seems like it would limit jounce travel.
7. How long are the links for the watts link? What about the length of the bell crank?
8. What are the tube diameters and wall thicknesses for this setup?
9. What is the weight of the whole system and how much of that is unsprung?

There a few questions to ponder. I assume at the very least Mark is an ME.
