Rear Grip Package 1999-2004 Ford Mustang Cobra

Reduce IRS wheel hop and improve handling with this Delrin Control Arm Bushing Package for upper and lower control arms. Fits 1999-2004 Mustang Cobra Eliminates deflection allowed by stock rubber upper and lower control arm bushings. Greatly reduces wheel hop because there is no bushing deflection. Precisely locates the upper and lower control arms for improved dynamic alignment. Handling is greatly improved because there are no unpredictable camber changes caused by bushing deflection. NVH and ride comfort virtually unchanged. Much easier to install than urethane control arm bushings. Installation tools included. This package includes MMIRSB-1 and MMIRSB-2. Handling is improved and wheel hop reduced by eliminating deflection allowed by the stock rubber control arm bushings. These Delrin bushings precisely locate the rear control arms, and maintain rear wheel alignment in a manner that is impossible with the compliant stock rubber bushings. Rubber bushings provide barely adequate suspension control, albeit the best noise and vibration reduction, but they cannot accurately position the control arms well enough to achieve maximum performance from the suspension. Wheel hop is a major complaint about IRS-equipped Mustangs. The un-damped compression of the rubber bushings in the rear suspension is the primary cause of wheel hop. That un-damped movement is amplified by repeated loss of traction. Wheel hop occurs because the rear tires continually oscillate between losing and then regaining traction. The extremely soft stock rubber bushings are the biggest contributor to this oscillation. The rubber compresses easily and then springs back, over and over again. To reduce wheel hop the stock rubber bushings must be eliminated.
