Ford Performance assembled Street Handling Pack is the perfect suspension system for the driver who wants improved handling and a lower stance but doesnt want or need all of the benefits of the Track Handling Pack. The Street Handling Pack includes pre-assembled struts, which do NOT require a spring compressor, and are ready to bolt-in! Give your Mustang the look and performance you want with the Street Handling Pack! NOTE: Mustangs that originally came equipped with the Performance Pack option only need to purchase the M-5300-X Street Lowering Springs to achieve the lowered ride height or upgrade to the M-FR3A-M8 Track Handling Pack. Please reference a Ford service manual for installation information and correct torque specifications. May require alignment after installation.
