Hi. 60 yr old motorcycle crash survivor amputee. Has anyone put one of these on an 2011 RSS? I think I need a longer axel but currently don't know the length or diameter of the existing one. If someone has done this mod please give me all the details. I know it will be cool looking if I can do it. Anyhelp from this great forum is appreciated. 2011 RSS SE5 Alloy Orange Metallic.
