I plan on staying N/A and don't ever expect to exceed 300 hp to the wheels. Looking to upgrade clutch and flywheel. have heard good things about orc's and os Giken. I'm deciding b/w these two: Orc 409 single disc hi-mu, silent, dampered: https://www.rhdjapan.com/home/produc...roduct_id=2575

and Os Giken Str series (dual clutch): https://www.rhdjapan.com/home/produc...roduct_id=1115

Since the orc is meant to handle up to 400 hp while the os str is meant for 500-600 hp, I though the latter would be overkill. However, OsGiken touts their STR series as being very streetable (but is this when compared only to twin clutch systems, or to single clutch systems as well?)

I would like to get the less agressive, less quiet, and more streetable choice for my application. I figured the orc 409 w/ upgraded options would be this choice, but am I wrong? Would the Ps Giken Str be a better choice.

 

I wonder if you could use this hub with ATS clutches?
