    Improved Handling. Obtain the handling and traction that your Cobra's IRS Suspension should have had from the factory by upgrading to the Maximum Motorsports IRS Rear Street Grip Package. This collection of modifications will significantly reduce that dreaded wheel hop and improve the overall handling and performance of your IRS equipped 4V Mustang.

    Reduce Wheel Hop. The Rear IRS Street Grip Package comes with everything necessary for a complete replacement of those stock, worn out bushings, provide proper alignment for improved handling and reduce wheel hop. Wheel Hop can cause damage to your differential cover due to violent movement so replacing your stock, weak components with those found in this package will prove to further protect your 4V investment.

    Street Grip Package Includes. Delrin Upper and Lower Control Arm Bushings, Urethane Differential and Subframe Bushings, a IRS Bumpsteer Kit and Adjustable Rear Sway Bar End links are all included. Specialty tools, all necessary hardware and detailed instructions round out this package to aid in making installation a breeze.

    Delrin Bushings. Upgrading to Delrin Control Arm Bushings will significantly reduce deflection, which will improve the handling of your Cobra and significantly reduce wheel hop. Soft, stock rubber bushings are the main culprit for wheel hop from the independent rear of your Cobra, so eliminate those inferior rubber bushings and upgrade to some high quality Delrin replacements.

    Application. This Maximum Motorsports Street IRS Rear Grip Package is specifically designed to fit 1999-2004 IRS equipped Cobra Mustangs.

        What is the difference between this kit and the Full Tilt Boogie Complete Rear IRS Bushing Kit and which one is the best to stop wheel hop on launch?

        • The Maximum Motorsports Rear IRS Grip Package and Full Tilt Boogie Complete Rear IRS Bushing Kit will be similar, however the Full Tilt Boogie kit will use a differential delrin diff mount bushing and UHMW subframe bushings, compared to the Maximum Motorsports Urethane bushings for these locations. This will translate to slightly better handling and wheel hop control from the Full Tilt Boogie kit, and slightly better ride quality from the Maximum Motorsports Kit.

        It says 99-04 cobra, would this package work on a 99 convertible GT?

        • This kit is designed for the 99-04 Cobra with IRS. Unfortunately it will not work with a 99 GT convertible.

            How it should be !

            This kit went in smooth even thought it's a long process. Instructions were perfect, and the kit includes everything you need. The car feels planted now and no more clunk when shifting !
