from what i remember when changing mine, i found the difference minuscule. not even noticeable, but i mostly bought it for the extra "reliability" and bling anyway.
the biggest difference i found to help the clutch, was by rebuilding the clutch with new friction and steel plates with a new beveled ring too. as yours is a RC8R does it have the slipper clutch installed, or the non slipper clutch? could be worth an inspection if you have the time.
