Here is an update on the OS Giken. Yes, it can get clunky on ya with warm RE11's and tight turns. I am running Motul 75w140 fluid. I may try the OS Giken fluid later if it get's on my nerves.

Mine only makes noise when I'm driving normal, slow sharp corners, never when I'm pushing it.

I have the Quaife in my base/touring,,,as i'm thinking it was about my only option with the factory 3.357 gearing.
I was told that if you lift a rear wheel (teeter it) while tuning up/down pretty sharp incline/decline...that the lifted wheel would only pull. As a Wavetrac unit won't do this.
Quaife is helical & no maintenance/while OS Giken is conventional clutch type & probably require a bit more frequent oil changes.
Gotta see what's available for your's.
My Quaife will draw even black lines as desired & make's 0 noise.....but i'm sure an OS Giken can be shimmed up tighter & potentially chirp a tire on very sharp turn's,,,as it's a more True posi unit.
