Kawahara Rear Blade Swaybars. Just installed. Took 3 min. minus dialation.

The blades are marked with grooves in about 1/8 increments and the main blades' support is marked with a center line for equal side-to-side balancing. No more guestimating.

The main (middle) support fits perfectly into the center of the stock upper chassis brace. Almost like it was planned from birth.

After fine tuning, both wheels have even lift as the opposite wheel is elevated. This was measured with the chassis on droop blocks. The trick is to lift each rear wheel and fine tune the set screws that hold the main rod (where the stock swaybar went). If you lift a wheel and notice the rod moving upward, turn in the set screw in until the rod is stabilized. You don't want to lock down the rod, because it still needs to move freely as the stock swaybar did.

Stock swaybar with 2 ballends and set screws weigh in at 8.5g.
The entire Kawahara swaybar unit weighed in at 11g.
Not to bad. And it looks bad @ssss!

What I should've done was measure the Mugen swaybars' wheel lifts to know what increments of the Kawahara's blades equal 2.0, 2.1, 2.2...
