Feal Coilovers 15-25 Mustang S550 / S650

Feal Coilovers 15-25 Mustang S550 / S650

Upgrade the suspension of your 2015-2025 Ford Mustang S550 or S650 with a Feal Suspension Coilover System. Developed using experience from top-level international motorsports and years of performance shock tuning, Feal Coilovers provide the control, adjustability, and performance needed for everything from spirited street driving to drifting, road racing, and drag racing.

Standard configurations provide approximately 1-2 inches of lowering capability. Multiple spring rate, damping, and driving-specific configurations are available so the suspension can be tailored to your Mustang's weight, tire setup, intended use, and desired ride characteristics.

IMPORTANT: These coilovers are NOT compatible with MagneRide-equipped vehicles in their factory configuration. The rear lower control arm must be replaced with a non-MagneRide-style arm.

Default Spring Rates:

• 441: 8k Front / 14k Rear
• 441+: 8k Front / 16k Rear
• 441 Drift / Heavy: 12k Front / 14k Rear
• 441+ Drift / Heavy: 12k Front / 16k Rear
• Standard Lowering Capability: Approximately 1-2"

Damping Adjustability Options:

441 - 1-Way Adjustable
Rebound and compression damping are adjusted together using a single adjustment knob. This makes it easy to tune overall vehicle firmness while controlling chassis dive, roll, and suspension response.

441.5 - 1-Way Front / 2-Way Rear
Combines 1-way adjustable front dampers with 2-way adjustable rear dampers featuring remote reservoirs. This configuration offers an excellent performance-to-value solution for drifting and drag racing, providing additional rear suspension tuning without requiring 2-way dampers at all four corners.

Independent rear compression adjustment allows you to fine-tune traction for changing track conditions. Adjustments can be used to dial in forward bite, side bite, squat, and bottoming resistance.

442 - 2-Way Adjustable
Features 2-way adjustable front and rear dampers with remote reservoirs. Rebound and compression are independently adjustable, allowing precise control over chassis roll, weight-transfer rate, traction, and suspension movement during the compression stroke. Rebound adjustments do not alter compression force, allowing the two characteristics to be tuned independently.

443 - 3-Way Adjustable
Features 3-way adjustable front and rear dampers with remote reservoirs. Independent adjustments are provided for rebound, low-speed compression, and high-speed compression for maximum suspension tuning capability.

Low-speed compression adjustment allows you to fine-tune chassis movement caused by throttle, braking, weight transfer, and smoother bumps. High-speed compression adjustment provides control over bottoming resistance and wheel movement when encountering rumble strips, sharp impacts, and square-edge bumps.

Available Driving Setups:

Balance of Comfort and Performance
Provides an excellent overall balance of firmness, handling, and ride quality for spirited street driving, occasional track days, and performance-oriented daily use.

GT Comfort
Formerly known as Max Travel, this comfort-oriented configuration provides slightly increased firmness compared with the OEM suspension for improved stability while maximizing shock and spring stroke for superior compliance. GT Comfort allows for approximately 1" of lowering or up to 1" of lift.

Road Racing with Street Tires
Uses firmer shock valving and spring rates for improved chassis control on road courses when utilizing street-oriented tires with a 200 UTQG or higher rating.

Road Racing with Racing Slicks
Uses substantially firmer shock valving and spring rates for maximum chassis control when running racing slicks or competition tires rated below 200 UTQG.

Drag Racing
Optimized shock valving and spring rates provide greater control over front-to-rear weight transfer to help maximize straight-line traction and launch performance.
