ARC adjustable sway bars?

[NotableGuest]

Anyone know anything about these? They look interesting but I'm not sure about the sliding mounts...

21mm rear bar! Jesus

I've never seen them before. BTW they are Auto Refine Co, Ltd. (http://www.autorefine.co.jp/stb_application/stb_mazda.html) not Abbey Road Company (http://www.arc-brazing.co.jp/).

They're for NA6 but have long been out of production. Specs say they are adjustable from 1.51 to 2.10 times stiffer than stock 19mm/12mm bars. It's hard to say what they were thinking with the adjustable control arm/ end link mounting point. Perhaps it's to accommodate the full range of rear sway bar adjustment at varying ride heights without interference with the coilover assembly. Also, if they're not the same geometry as stock bars then you can't compare diameter/roll stiffness apples to apples since the length of the moment arm appears different.

Thanks for the thorough reply! Yes, I am reminded of the 2 different ARCs...
