FIA HTP Will be renewed 

1976 Porsche 911 3.0 IROC/RSR for Group 4

A rare opportunity to acquire one of the most successful historic Porsche race cars in Denmark.

Driven and developed by Danish semi-professional driver Kenneth Vagtholm, this car represents decades of continuous development, proven race performance, and documented history.

This is a fully sorted, race-winning, turn-key historic Porsche with strong collector appeal.

🏁 

The IROC / RSR Connection

The International Race of Champions (IROC) series became one of the most iconic chapters in Porsche racing history. Only 15 original Porsche 911 IROC/RSR cars were built by Porsche.

This car is built to authentic 3.0 IROC / RSR specification, offering one of the closest experiences to the legendary factory-built IROC cars, both technically and visually.

Cars built to correct and competitive IROC / RSR specification are highly sought after worldwide and continue to attract serious interest from racers, collectors and investors.
