The FFR Roadster is a replica of the AC Cobra: see also Legacy of the FFR Roadster.

BUILD MANUAL covers 12 major topics in clearly written how-to sections illustrated with over 650 photos, drawings, and diagrams. Click on the 12 tabs above for a overview of our detailed instructions and technical assistance. Full access requires a membership pass.
