Eibach Pro-Kit is a progressive-rate lowering spring set for the SN95 Mustang SVT Cobra with independent rear suspension. It lowers the coupe 1.4 in and the convertible 1.5 in at both ends, dropping the center of gravity for flatter cornering and a tighter stance. Eibach specifies this kit for IRS cars only and tested it with factory dampers.
