A one-of-a-kind creation of unmatched quality and authenticity: This Porsche 911 RSR IROC has been meticulously rebuilt over several years with an uncompromising focus on originality – by a renowned Porsche engine builder and bodywork expert who spent decades working in official Porsche factory racing programmes, including Le Mans and Paris-Dakar.
