Whether you're looking to add a little more performance to your daily driver or planning to push the limits with a full custom project, Stage 3 Motorsports has the parts to help you get there.

Easy Upgrades for First-Time Modders

Not every build starts at full throttle. If you're working on your first Mustang or simply want to make the car more enjoyable to drive, there are a few simple upgrades that offer great results without requiring deep mechanical experience.

Recommended Beginner Mods:

• Cold Air Intakes – Increase airflow for better throttle response and improved engine sound
• Axle-Back Exhaust Kits – Add volume and tone without overwhelming the cabin
• Tuning Devices – Improve drivability, sharpen throttle feel, and unlock small power gains
• LED Lighting Kits – Replace outdated bulbs with brighter, modern options for better visibility
• Lowering Springs – Improve ride height and handling while reducing body roll

Build a Stronger Street Performance Mustang

The New Edge V6 might not make GT-level power from the factory, but it can become a serious street machine with the right combination of bolt-ons, handling parts, and supporting upgrades. The key is to focus on airflow, suspension, and drivetrain improvements that deliver noticeable results.

Performance-Oriented Upgrades:

• Cat-Back Exhaust Systems – Boost exhaust flow and give your V6 a deeper, more aggressive tone
• Throttle Bodies and Spacers – Improve intake velocity for a stronger mid-range pull
• Suspension Packages – Combine springs, dampers, and sway bars for sharper response
• Brake Kits – Upgrade rotors, pads, and lines for confident, fade-free stopping power
• Performance Wheels and Tires – Wider wheels and sticky rubber improve both traction and appearance

Push the Limits with a Track-Ready V6 Build

If you're chasing lap times or planning to take your Mustang to autocross or HPDE events, the V6 platform can still deliver when properly prepped. With its lighter nose and simpler drivetrain, it offers a fun and rewarding track experience when combined with the right parts.

Track-Focused Upgrades:

• Chassis Bracing and Subframe Connectors – Increase rigidity and improve turn-in stability
• Cooling System Upgrades – Keep temperatures under control during extended sessions
• Drivetrain Mods – Add a limited-slip differential and re-gear for better corner exit traction
• Coilovers and Adjustable Suspension – Fine-tune your handling balance for any road or course
• Racing Seats and Interior Upgrades – Improve driver comfort and control for serious builds
