I have found that KYB markets 6 different models of dampers in Japan. All we get is the GR-2 and the AGX. I am considering two of these models. I know that I have heard of people running the light blue SR Special struts in the US. I also know someone will say just get the Koni yellows, but its always nice to have options---IF the more aggressive of these KYBs can handle high rates and not blow. If anyone has experience with any of these, please chime in.
