2026 NSR Porsche 997 Challenge

Porsche 997 Challenge: Where Precision Meets Passion

Experience the exhilarating world of the Porsche 997 Challenge, a race where engineering mastery meets the relentless pursuit of speed. Each pulse-pounding lap showcases the perfect marriage of performance and luxury, highlighting the 997’s renowned engineering prowess. The 997 encapsulates Porsche’s rich legacy, blending timeless aesthetics with cutting-edge technology. Its striking silhouette commands attention on and off the track.

Join in a race of camaraderie and competition where we put our skills to the test by racing NSR Porsche 997 in their Anglewinder configuration on our Rally and Road track. The track for the day will be up to chance, depending on the toss of a coin, forcing racers to find a setup balance between road and rally.

This race will be a spicy one for competitors as we try to thread the performance needle between Road and Rally track, decided by a coin flip on race day.  The extra shake of spiciness on top of that is that we will be trying to tame angle winder setups for both tracks in one build!
