The direction of the bends doesn't make any difference. The bar is under no torsional tension until one side or the other induces vertical movement on the bar via the links. As one side loads and forces the link up, the other unloads and pulls it down and at this point the bar rotates into torsional tension, hence the thicker the bar the more load it takes to generate any torsion and thus less roll.

 

There is no problem with adjusting an anti roll bar asymetrically, as long as any static pre-tension is taken out. If any pre-tension is there it will add spring rate to one side and take it away from the other. So ideally, adjustable drop links are needed but for a road car a small amount of pre-tension can be acceptable and most drivers will not notice. If you are chasing the last tenth of a second around a track it will make a difference.

 

yes so unless you are planning on tackling ovals not a lot of point. i mean you wouldn't jack corner weights on a car again unless is was ovals or only RH bends.

"As one side loads and forces the link up, the other unloads and pulls it down"
also this is not right one side loads the other side experiences the same force - you seem to be describing what the springs do?

no point arguing about this if ARB manufacturers thought it was a good idea they'd say so.

 

Without going OTT with the computational stress/strain/shearforce malarky, I was just "allowing" for the possibility that the lever ratio would alter slightly due to moving the mounting point of the drop-links relative to the pivot point of the ARB.

agreed as before. bet the needlework comes in handy with worn seat bolsters?
