I see that there exists a Yosh kit to swap out part of the 17+ clutch to make it possible to tweak the amount of slip on downshifts. I have come across a few references that the Yosh kit is just an 11-16 OEM clutch in which it was possible to tweak the amount of slippage. Anyone have any first hand experience in installing an 11-16 OEM clutch assembly into a 17+?
