Eibach ProKit Mustang Cobra 99-04.

Ford: 1999-2002 Mustang Cobra, with IRS rear suspension, 1.4 in. lowering front and rear, steel, powdercoated, Pro-Kit Springs

Eibach's Pro-Kit is their most popular kit--and there's a reason for that. This kit reduces fender gap to give your vehicle a lower, more aggressive stance. Plus, the springs lower the center of gravity to improve handling during acceleration, cornering, and braking. They'll lower your vehicle a total of 1.4 in. without having to change your shocks.
