New Porsche 718 Cayman GT4 Clubsport featuring natural-fibre physique parts

Posted on 03. Jan, 2019 by in Porsche Canada

For a initial time, a near-standard mid-engine racer comes in twin versions ex-works: a “Trackday” indication for desirous pledge racing drivers and a “Competition” various for inhabitant and general engine racing.
