Alright guys, I'm looking to borrow your sway bars so I can test them and get accurate rates that we can all benefit from.
I have built a sway bar test rig that should work for all the supra bars, if not, I'll make another one. This is the rig I used to test S13 sway bars before.
Basically, I load the bar with several different weights and measure the angular displacement. When used with the moment arm length, also measured, this will give me the ft-lbs/deg measurement for the stiffness of the actual sway bar. This will factor into spring rate selection and suspension tuning and is very valuable to have. It's just as important to know as actual spring rate and it's a shame that these rates aren't published.
So if any of you guys would be interested in helping me with this. I figured we could split shipping or possibly donations from other members who are interested in this testing could help offset this cost. I will publish the rates of all the bars that I test. I'm looking for both Mk3 and Mk4 bars. And I figure that now, since it's getting cold out and the racing season is pretty much over, a lot of cars are just going to be garaged or getting work doen for the winter and the sway bars will just be sitting around doing nothing, so it would be the best time.
Please post here and/or PM me if you have sway bars that I could test. I have stock Mk3 bars, but I need everything else. I think this will benefit all of us, so if you have the bars and would be willing to participate, please let me know.
