Tested at Speed: Xignature’s EZ-Release Plate Holder Runs Simola on Alfa Stelvio QV

Knysna, South Africa - During this year’s Simola Hillclimb, Xignature’s EZ-Release magnetic plate holder was tested at speed on the Alfa Romeo Stelvio Quadrifoglio, driven as part of Alfa Romeo South Africa’s official entry.

While the event marked the product’s first appearance at Simola, the Xignature team was confident. The EZ-Release system has already proven its reliability on road and track cars globally, including 1000+ horsepower builds and some of the most powerful and prestigious vehicles in the world. Our client base includes performance leaders such as Ferrari, Porsche, McLaren, and tuned AMG models, where high speeds and aerodynamic stability are non-negotiable.

Race Conditions. Road-Ready Confidence.

Mounted cleanly to the Stelvio QV’s factory bumper, the EZ-Release plate holder held firm throughout the full hillclimb run. The system’s flush fit, reinforced adhesion, and internal magnetic locking features worked together to deliver stability, even under launch, cornering, and braking at pace.

“We didn’t test it hoping it would hold up, we knew it would,” said the Xignature team. “This is the same system we deliver to clients pushing beyond 300km/h.”

Engineered for Performance. Proven Publicly.

The Stelvio Quadrifoglio, Alfa’s 375kW flagship SUV, is a serious performance machine. Its presence at Simola made it the perfect showcase for a plate holder designed to match the same standard: OEM+ form, real-world function, and road-legal usability.

The EZ-Release system allows for quick, tool-free removal for cleaning, show plates, or detailing, while maintaining a clean visual finish when mounted. It’s already become a favorite among detailing professionals, luxury car collectors, and club-level motorsport clients who need both convenience and integrity.

Another Milestone. Same Mission.

This public demonstration reinforces Xignature’s commitment to building solutions for cars that demand more, not gimmicks, not mass-produced plastic, but engineered products made locally with care, accuracy, and trust.
