The Flat 6 Motorsports 718 GT4 Track Performance Kit is designed for the enthusiast looking to maximize the chassis set up of the 718 GT4 Cayman for track use. This kit is optimized with thorough track testing, backed by data analysis and driver feedback. The enhancements bring improved grip, cornering speeds and balance. The result is a significant reduction of lap time and improved driver confidence.

The 718 GT4 comes from the factory with a detuned mindset to preserve the gap between the Cayman and 911 models. As a consequence, the handling promotes understeer and reduced cornering speed. The car scrubs front tires upon corner entry causing the vehicle to reduce slip angle and plow through corners. Flat 6 Motorsports focuses on correcting the alignment and balance of the car to promote cornering speeds and improved grip levels at the front of the car. This data-proven approach allows more direct corner entry and improved cornering speeds. The Track Performance Kit yielded an impressive -5.63 second reduction of lap time at Circuit Florida's 1.7 mile circuit. It promoted minimum cornering speeds of +4-5mph throughout the majority of the turns with improved grip and balance. This kit closes the gap between the 718 GT4 and 718 GT4 RS on track.

This kit is available in two different configurations. The Performance Kit is everything we developed in our testing and designed to be used on track but still offers street usability and functionality. Our High Downforce Kit is offered for customers looking for advanced track use or club racing where permitted with regulations. The High Downforce Kit further improves downforce for added stability for high speed tracks. Flat 6 Motorsports utilizes the best in industry to develop the Track Performance Kit. Proven, high-quality solutions are used to provide hassle free usability with world-class performance.
