C8 ZR1 & ZR1X Race Ready Tuning 1RR Performance Package

The Race Ready 1RR Performance Package for the 2025+ Chevrolet Corvette ZR1 and Chevrolet Corvette ZR1X was engineered to elevate the already extraordinary LT7 platform to an entirely new level of performance while preserving the factory refinement, comfort, and drivability expected from Chevrolet’s flagship supercar platforms.

Designed as our entry-level performance package for the twin turbocharged ZR1 and hybrid-assisted ZR1X platforms, the 1RR Package delivers an incredible 1100+ rear wheel horsepower on the ZR1 and 1275+ combined all-wheel horsepower on the ZR1X — representing roughly a 150 horsepower increase over factory output while maintaining OEM-like drivability and seamless power delivery.

The 1RR Package focuses on maximizing airflow efficiency, reducing exhaust restriction, optimizing throttle response, and refining the factory calibration to unlock the full capability of the LT7 powertrain. Every component was selected to enhance performance while retaining the sophisticated driving characteristics that make the ZR1 and ZR1X exceptional both on the street and at the track.
