The vehicle in detail

Unique rebuild based on the original IROC RSR - built by Porsche racing specialists

A vehicle that rarely exists in this quality and authenticity: This Porsche 911 RSR 3.0 IROC was built over many years to the highest standards by a renowned Porsche engine builder and bodywork expert - a man who worked for decades for official Porsche works racing, including in the Le Mans and Paris-Dakar programs.

The entire body is based on an original IROC RSR, which was available as a reference vehicle for this project for the entire duration. The result: a unique rebuild of the legendary Porsche RSR IROC - technically and emotionally indistinguishable from the original. The interior was refined to the highest standards, including a carbon steering wheel, leather applications and turbo seats, transforming the unique vehicle into a road-legal racing machine suitable for everyday use.

Highlights

  • Professional bodywork by former Porsche racing mechanics
  • Exclusive use of original Porsche racing parts
  • "From-the-bolt" full restoration - every part overhauled, replaced or improved
  • Built on the exact model of an original IROC RSR, which served as a reference during the project
  • Only original Porsche components in the engine, chassis and body
  • Unique collector's car with true racing spirit
  • On a par with an original IROC RSR in every detail
