The S650 Mustang has officially arrived, and it’s a beast. Ford didn’t just iterate; they evolved. But for the modern muscle enthusiast, "stock" is just the starting line. To truly unlock the potential of that dual-throttle-body Coyote, you need the right parts, the right plan, and zero compromises.

Choosing the best S650 Mustang performance parts isn't just about picking the most expensive item on the shelf. It’s about synergy. It’s about building a vehicle that dominates the street and the strip without breaking a sweat. Whether you’re chasing 700+ horsepower or a track-ready stance, this guide breaks down the high-performance outcomes you need.

Push The Limits: Cold Air Intakes

Your Coyote engine is essentially a giant air pump. The more cool, dense air you can cram into it, the more power it puts down. The S650 dual-intake design is unique, and upgrading it is one of the fastest ways to see immediate gains.

JLT Performance vs. Steeda

When comparing cold air intakes (CAI) for the S650, two names consistently lead the pack: JLT and Steeda.

• JLT Performance: Known for maximum airflow. Their S650 kits focus on large-diameter tubing and high-flow filters that minimize restriction. If your goal is pure, unadulterated power for a drag build, JLT is a heavy hitter.
• Steeda: Steeda takes a more engineered approach, often integrating heat shields and CAD-designed velocity stacks. Their focus is on consistent intake temperatures and "no-tune" options that still deliver measurable gains.

Unleash The Sound: Exhaust Systems

The stock S650 exhaust is decent, but "decent" doesn't turn heads at a car meet. You want that signature American V8 growl: deep, aggressive, and loud enough to notify the neighbors you're leaving.

AWE Touring vs. Stainless Works

• AWE Tuning: Their Touring Edition Exhaust for the S650 is a masterclass in acoustics. Utilizing 180 Technology®, it cancels out drone while maintaining a ferocious exterior bark. It’s the perfect balance for a daily-driven muscle car.
• Stainless Works: If you want a more "raw" racing sound, the Stainless Works Legend or Redline series is the way to go. Built with 304 stainless steel and aggressive X-pipes, these systems are designed to push exhaust gases out with zero resistance.

Control The Beast: Suspension Upgrades

Power is useless if you can't put it to the pavement. The S650 platform is agile, but to eliminate wheel hop and body roll, you need to upgrade your chassis.

BC Racing vs. Steeda Suspension

• BC Racing: For those looking for a "slammed" look without sacrificing ride quality, the BR Series Coilovers are the industry standard. They offer 30-way damping adjustment and full height adjustability, allowing you to fine-tune your S650’s center of gravity.
• Steeda: If your goal is the road course, Steeda’s "Stop the Hop" kits and lowering springs are essential. They focus on geometry and bushing stiffness, ensuring your IRS (Independent Rear Suspension) stays planted under heavy load.

Select Your Stance: Wheels & Tires

Wheels are the soul of your build. For the S650, you need wheels that are lightweight, durable, and wide enough to house the rubber required for 5.0L power.

Weld vs. Forgestar

• Weld Racing: The ultimate choice for drag enthusiasts. A set of Weld S71s or Laguna wheels provides the strength needed for high-torque launches while shaving significant unsprung weight.
• Forgestar: Perfect for the "Modern Muscle" aesthetic. Forgestar’s rotary-forged technology allows for custom offsets and deep concave profiles that fill the S650 wheel wells perfectly.

Maximum Gains: Forced Induction

Ready to cross the 700-wheel horsepower mark? The S650 is built for boost. While the factory internals are strong, adding a supercharger transforms your Mustang from a pony car into a supercar killer.

• Whipple Superchargers: Their massive twin-screw blowers provide instant torque and a high-pitched whine that is unmistakable.
• VMP Performance: VMP offers specialized kits and tuning for the 2024+ GT, focusing on integrated cooling and turn-key reliability.
