2010 v50 Upgraded Swaybars - 90-degree angle endlinks?

[packetfire]

Swaybars - why would anyone tolerate THIS?

2010 v50 is a wagon, so its rear-end is draggin' without a seriously thicker sway bar than the stock swaybar.

But just look at this - how is this supposed to "stiffen" anything, even with a much thicker sway bar? One has to hunt to find a sway bar that can be "directly" attached without these 90-degree end links. How do these not defeat the entire purpose of "stiffening" the rear end?

Not sure what you are asking here?
I have these same style on my upgraded rear sway on my c30. I intentionally switched from the "stick" style to HD units of this type after seeing the shape the bushes were in on the "stick" style. The ball joints allow for proper movement without wear on the rubber bushes. Even most "solid" end links still have a use heim joints to allow for proper movement/alignment of parts.
I assure you that the sway bar still works with the type of set up you are asking about. MANY manufacturers, Audi, Benz, etc. use this type of end link from the factory. Also, many aftermarket performance companies use this style as well.

Sorry, I will be more detailed.

1) The sway bar works by only twisting so much.

2) Thicker bars twist less, so thicker is much more gooder for wagons.

3) But these 90 degree end-links seem to provide a new "weak point", and can twist themselves, before the sway bar twists.

So, I am thinking that one needs a sway bar with a 90-degree rotation of the "bolt tabs", to allow a straight bolting of the sway bar to the frame. Yes, those bushings will wear over time, and will need to be replaced, and there are "upgraded" bushings made of stiffer materials that won't wear out so quickly.

But what confuses me is why so many cars seem to introduce this thinner, and easier-to-twist linkage on a part that is intended to resist being twisted so as to keep the rear end more stable under load on curves and such.

It’s not to resist twisting so much as it’s to “transfer” the “twist energy” from the compressing side to the lifting side in an attempt to keep the contact patch as great as possible side to side.
ie. left turn, right rear loads and plants while rear left wants to lift. As the bar loads it twists and attempts to load the left rear and unload the right rear in order to “try” to balance the load from side to side keeping the car more level throughout turns.
