Transform Your Mustang to a Street-Legal Racecar. By creating a drop lower than the legendary Pro-Kit, the Eibach Sportline Springs set brings out racecar-level handling from your Mustang. This is through aggressively bringing down the Mustang’s center of gravity by employing precision-engineered progressive spring rates. With this lower center of gravity, you can now say goodbye to nosedive when hard braking, body roll in the corners, and squat during rapid acceleration.
Lowered Stance. Not only does a lower center of gravity translate to better handling performance. But, it also gives your Mustang a more aggressive stance. These Sportline Springs lower the ride height to approximately 1.5″ in the front and 1.3″ in the rear to reduce the ridiculous factory wheel to fender gap.
Progressive Design. Progressive springs (also known as variable-rate springs) are designed to be more compliant when riding over rough and uneven surfaces like public roads. Progressive springs are engineered with a low starting spring rate that increases as the spring compresses. Variable-rate compression allows for a smoother ride, while still providing good handling characteristics when pushed hard. This makes progressive rate springs a popular choice for daily street-driven Mustangs.
Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your stock size wheels and tires, as well as AmericanMuscle’s pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.
Professional Installation Recommended. Seeing that a spring compressor is required for installation of these Coil Springs, Function Factory Performance recommends professional installation. With the proper tools, installation can be completed in about three hours. Please note that an alignment is highly recommended after installation.
Technical Note. The Springs are not compatible with vehicles equipped with the MagneRide Suspension.
