Stage 1 Street/Track

Stage 1 NA Street / Track Package

The Vertex Motorsports Stage 1 NA Street / Track Package is a complete naturally aspirated performance upgrade designed to dramatically improve handling, sound, responsiveness, and overall driving confidence—without sacrificing street reliability. This package is engineered for Mustang owners who want a balanced, track-capable setup that performs just as well on the street as it does during aggressive driving or open-track events.

At the foundation of this package is our S550 Suspension Overhaul Package, which transforms the chassis by eliminating unwanted deflection, reducing wheel hop, and sharpening steering response. Performance coilovers, upgraded bushings, IRS bracing, and precision alignment components work together to keep the car planted and predictable under hard braking, cornering, and acceleration.

To complement the improved chassis control, the Stage 1 package adds long-tube headers and a performance cat-back exhaust, unlocking additional naturally aspirated horsepower while delivering a deep, aggressive exhaust note. A custom calibration is then applied to optimize throttle response, fueling, and power delivery for both street and track use.

Power is efficiently transferred to the rear wheels through a 1-piece driveshaft, reducing rotational mass and drivetrain loss while improving throttle response. A driveshaft safety loop is included for added safety and track compliance.

The package is completed with professional installation, ensuring every component is installed, aligned, and dialed in to work as a cohesive performance system.
