Default rear lca's job

i was thinking about this and this would make sense if this is how they work.

i always hear angle the lca's uphill 2*.

are TA cars using the upward angle on the LCA's to help seperate the housing from the body?

that would make sense why you would want them in the lowest hole of hte LCA brackets to give the car a better leverage point to push up against the body at a better angle and then in turn would push the housing back against the ground...

am i getting closer to what the hell these LCA's actually do?

Just take a pen, lay it on a desk, put one end against something that doesnt move and pretend its an LCA. Then push on the other end at various angles and you can see what makes 99% of an f-body rear suspension work (or not work) in a drag car.

But yea you describe how it works, except for the actual length of the torque arm its angle doesnt mean a whole lot unless its solid mounted in the front.

i think he means sliders and shackel mounts on the front..cant be solid because that could cause binding issues...and if what kp is saying is true then to hit tires harder all you need is more lca angle?

they usually have a slider in the front or a bracket that lets it pivot like the BMR. if it is mounted solid it will bind with the lca's.

more angle might do that... but it seems from parallel to 2* is plent for most cars...

well... im excited to get back to the track again
