Lance, you've got a lot more knowledge on this then I do and an actual set up to stare at. With that being said....In my mind, articulating the axle does not seem accurate, we used to do this with 4wd suspension but we were looking for clearance and droop. Finding a point in which the 4 link binds with everything disconnected may not present everything you need to see...does it travel that far with CO's and sway bar in place? What about chassis/body flex and forces applied on the mounting points?

I'm paying attention and do appreciate you sharing what you're learning!

I'm sure it's not 100% real world dynamic, but it's a start.

Think of it this way though, if the suspension is binding with everything else unhooked except trailing arms and a watts link, just think how hard it is going to bind once weight is on it and sway bars, springs and shocks are all hooked back up again. Talk about stiction...

We've been working on this for a while trying to come up with a reasonable answer, and we'll get there. I just saw an opportunity to share a visual demonstration we don't usually get to see and had to go for it.

I saw the FB post and read through the replies, it's a great conversation amongst friends. Could you achieve a lower roll center by changing the mounting points and not adding the watts? It seems in the video that the watts is what was hanging up the suspension, unless it was adjusted all the way to the point that it wasn't doing much of anything anyway....just thinking out loud.

Keep on keepin on!

Yeah, bunch of good guys I have for friends...all just trying to learn how to make our cars better together.

I guess you could rearrange the uppers to help the roll center, not sure how good you could make it though and even then it would still be a fixed roll center, not adjustable.

Why go through all the trouble of rebuilding the rear suspension and not make it as good as it can be? I'm more in the clean slate frame of mind since I know I'm redoing it all anyway.

Bye-bye backseat!

[SSLance]

Oh that ship sailed a few years ago already...

[Flash68]

That's a nice clean back seat area there Lance.

That's all I got. Carry on with the Basher.

[WSSix]

Well, this just got more interesting that's for sure. Keep us posted, Lance, and good luck.

[SSLance]

Thanks guys... It's good to have goals...especially when it's single digit temps outside and everything is covered in ice.

Spring will come soon enough though, so time to get cutting soon.

[DBasher]

It'll be interesting to see what you come up with, Lance. I wonder how much lighter the car will be without that shag carpet.
