Wiisass pretty much summed it up with his response. The heims joints wont cause the chassis to really be absorbing any real extra force, it will mainly be on the lca. If that was the case saying the heims joint will negatively impact life... means that larger swaybars would do the same thing.
slideways2004: the largest swaybar was included in a "handling package" (I dont know what the exact title was) which included hicas.
Wiisass:
The generalization on hollow vs. solid tubing was actually from the hotchkis site. By proportianate wall thickness I meant the average, most manufacturers seem to use a very similar wall thickness in proportion to the diameter.
When I commented on the weight of the bars as much as 10-20lbs I was going on shipping weights from some different websites. So yes, you ACTUALLY can save that much weight.
When I spoke on braking/acceleration I was making a statement based on the fact that you are removing weight from the car. That was my only point of reference. It isnt obviously a huge impact that will give you .3 in the quarter mile, but it all adds up when your shaving it off. If you buy a carbon fiber hood for weight, then something like this for weight is in the same ballpark.
Absolutely correct the length of the sway bars will impact the overall spring rate but we only have so much data provided to us to base things off of.
I wish swaybar manufacturers developed some sort of a standard for testing. For example, clamping 50% of the bar and testing the spring rate where the endlink attaches. Doing so on both sides of the bar and averaging the rate.
