The hatchback-style EK9 has a large rear hatch opening, which means the body rigidity is a weak point. The rear pillar bar, rear monocoque bar, and rear cross bar are three items that make up for this lack of rigidity and are highly effective in reducing distortion and twisting of the body. To install the cross bar, the pillar bar and monocoque bar must be installed at the same time. It cannot be installed alone. It is a bolt-on installation, so there is no need to drill holes or perform other processing, making it easy for users to install it themselves.
It is introduced on Ameblo's "M&M HONDA's Honda Honki."
