Small experiment in doubling sway bars.

Post by DevC »

2 stock sway bars doubled up, crap channel bar and u-bolts to attach second bar to original bar.

Works ok :D

Seems like it would bind on compression and make the ride much firmer.

Nope, no binding, looks janky, but works well.

I guess I don't understand the physics of it entirely, but wouldn't the force to bend one be the same as the force to bend another one of the exact same diameter? i mean, i know that ropes and things like that gain strength by being stranded together, but in this case, is the u bolt enough to make them be considered as one piece?

LOL YES. That brings back good memories. Yeah...I watched that show. Probably every episode. Some of the most ridiculous shit I've ever seen put on a car on that show.

To the original poster, What about cutting the ends off and welding the bay to the original bar, say an inch or two apart. maybe that'd be more efficient?

It's an experiment I suppose, so we don't know the actual effectiveness (like a percentage). But, when you go to that amount of labor, wouldn't it be better to go to an outback sway bar for like 20 bucks? It'd be nice to know (for the experiment), if two swaybars is actually doubling the torsional stiffness.

I stole this from the forester forums, who i believe stole it from Oakos.

It took me 20mins some scrap and $4 in u-bolts and was completely reversible. And I have since installed new gr2's in the rear and removed the second bar.

It was a lot stiffer and did increase oversteer nicely but for cruising around it did feel slightly off balance because you could feel the front articulating more then the rear.

Definatly not an ideal replacement for a nice set of proper upgraded bars......obviously haha
