Suspension needs & thinking outside the box
Here's the challenge: I would like to build up some type of suspension dampening system that's light weight and have super low cg. Any ideas are welcome. I don't really want to have the standard shocktowers and coil overs, and not interested in low pro towers/shorty shocks. Here's what I'm working with:

Create your own pull rod suspesion

Low CG you could simply flip over the dampers... But you'd still need the shock towers..
#7
Flip over dampers is giving more mass to the suspension.
#8
spring in the suspension as an old BMT?

Yes. They are usually referred to as "clock springs". Ride height/corner weight adjustment was via a set screw in the suspension arm (which is visible in the photo). Dampers were conventional piston, just like on 99% of all RC cars. There were a few different springs available, differing in wire diameter to get different spring rates.

A flat steel leaf would work fine for springing. Not only does it keep the CG low, but you could arrange to make the active length infinitely adjustable, giving all possible spring rates (within a limited range) using just one leaf... Just like the Awesomatix!
It will be interesting to see what you come up with for low-CG dampers. The Awesomatix rotary damper is a pretty good solution, but maybe there is a better one?

Make a solution with pull rod suspension (Not push rod) and place the damper right above the chassis plate.
Dont know if you can make it with your chassis but it would definately be new

You might like to try some friction dampers. Try looking for a book called Shock Absorbers Handbook, it´s easily found in pdf, it has a few ideas that you might like to try.
I too agree that the next big RC revolution lies in the dampers design. Today´s dampers are probably just as efficient as 1930´s technology. Lots of hysterisis, and unwanted cavitation, not to mention that they all probably behave linearly. IMO, the solution would be an evolution in the piston design, with a digressive behavior, and lightweight body parts.

What about the Tigermoth LCG V10
