The hatchback style EK9 has a large rear hatch opening, which means the body rigidity is a weak point. The three parts that make up for this lack of rigidity and have a great effect in mitigating body distortion and twisting are the rear pillar bar, rear monocoque bar, and rear cross bar. The rear monocoque bar is fastened together with the genuine rear beam at the bottom of the body. It is a bolt-on installation, so there is no need to drill holes or do any other processing, so even users can easily install it themselves.
It is introduced on Ameblo's "M&M HONDA's Honda Honki."
