Blank carbon-fibre dashboards for a variety of applications. Measuring 1500mm across and 240mm high with a rolled bottom edge these dashboards are suitable for many popular kit car applications.

Available in two patterns - either with the 2x2 twill carbon weave going horizontally across the dashboard or with the weave going diagonally across the dashboard.
