Credit where credit is due.  They actually aren't full of shit.

Nice little nugget of info.

It might be effective, but it really is a half-cocked solution.

Great for suspension bind.

I was looking at that thinking how the fuck is that not going to bind. absolutely retarded idea.

I like the idea of using the LCA bushing compliance to allow for suspension travel...

Im not sure what the point youre making is.

[EDIT]Ok, Im not sure if this is what you were trying to point out. But I get what HiProfile was saying now. I already have a Full Race Traction Bar, and now after that link, I get the geometry part of it. So If I were to maybe make rear radius rods to the rear crossmember, but make them mount inline with the LCA pivot point and traction bar/radius rod, I should be able to avoid binding, and hopefully keep my tires from sucking into the bumper?

After reading that, Ill definitely be making my own.

Do you guys think if I made the same style rear bars, but mounted them inline with the LCA pivot spot, and rotated the heim 90* to pivot on the same axis as the LCA, it would be optimal? Or just move the mount location to be inline with the LCA pivot, and keep the heim as it is with the K-Tuned setup?

And actually, my Full Race has both heim joints mounted opposite from the way K-Tuned mounts theirs as the LCA. Theyre mounted in the same orientation as the traction bar side, using a bracket to rotate the heim to be perpendicular to the ground, so to speak. Makes sense, to allow the suspension to travel. So Im thinking I should obviously do the same with the rear bars. Make brackets at the LCA and the rear crossmember, to mount the LCAs vertically instead of horizontally, and then keep the mounting inline with the LCA pivot, and it should be perfect. Right?

Looking at the EG A-Arms, maybe find a way to solid mount the radius rod to the LCA, and then have a heim on the rear crossmember, to pivot at the same axis? Maybe even make the radius rod at a 90 or close, with triangulated support, so that it really does pivot at the same axis and angle?

And for some reason, as I was typing this, these came to mind.

Sure, that doesnt completely apply. But it just gave me the idea really.

I could possibly have the radius rod attached solid to the LCA, have it point towards the back of the car, and then 90 or less inwards. And then have a heim joint on that end, and have it mount inline/parallel with the LCA pivot point. Should mimick the EG A-Arms pretty well I would thinking, and not cause any binding. But all the while, reinforcing the LCA to reduce lateral movement. Right????

My point was that they at least understand basic geometry and mechanics principles.  Their engineering data seems to be somewhat legitimate from what I could see. 

Methinks that the LCA is still moving forward because of the revolute (that heim joint allows rotation in 3 axes) joint at the radius rod to LCA attachment point in conjunction with LCA bushing compliance.  I suspect there are other factors at work here as well, but this is one of the main ones it seems.

It would be interesting to load it up on a chassis dyno that can properly load the engine/drivetrain, and observe the reactions of the LCA.  I bet that fucker twists a bit about 2 axes.

Wish the car was still running. I could have put the GoPro under the hood, and seen how the LCA acted. Thats a good idea for sure.

I wouldn't be surprised if it was just bushing flex and the lca pivots at the traction bar connection.

What bushing at the traction bar connection? All of my bushings are Energy Suspension, and new. They have about 5k miles on them maybe?

400 dollars on bearings is for H-T faggots.

true facts.
It'd be a nice upgrade, but the bearing for the shock ain't really needed, and the inboard one would be a fun task with a mill & a HF press.
