Hmm. Harder isnt proven to be better. I would think maybe the material is denser but will absorb more force and will deteriote.
Put it this way - hardrace is copy parts , not grossly engineered / designed like MUGEN or J's RACING oem replacements. Only time will tell if these hardrace bushes last.
I worry that yet again , you lot are falling for this "hardrace y0 150% harder = BETTER". Rofl. That , and its alot cheaper than OEM parts.
