Kenny Brown Extreme Matrix Kits for 1979-2014 Mustang, SVT Cobra, Boss 302 and Shelby GT500

May 2013

Wauconda, IL --  Kenny Brown’s Extreme Matrix Kit represents the ultimate in under car chassis support for 1979-2014 Mustang, SVT Cobra, Boss 302 and Shelby GT500.  This complete chassis support system is designed to maximize strength at the center section of the car with no loss of ground clearance and minimal addition in weight creating the most rigid subframe support system available for Late-model Mustangs.

In 1989, Kenny Brown introduced his critically-acclaimed Doublecross Subframe Connectors and focused the market in a whole new area of performance, chassis support.  In 1994, Kenny released his Super Subs, an extra heavy-duty version of the original subframe connectors.  Following that, Jacking Rails to further reduce chassis flex and allow for convenient jacking positions along both sides of the vehicle.  To top the system off Kenny later released the Extreme Matrix Brace to act as a support “bridge” connecting the subframe connectors with the Jacking Rails at the outside of the car, through geometric triangulation to form the Extreme Matrix Kit.

Power-robbing chassis flex and twist, caused by engine torque, acceleration, cornering, braking and irregular road surfaces, are formidable enemies when adding power and more performance to contemporary Mustangs.  Born out of Kenny’s need for increased chassis rigidity in the high-performance Mustangs he builds, the concept of maximizing chassis support has grown to an essential component in managing power, ride and handling in today’s Mustang platform.

The Extreme Matrix Kit is designed to fit all 1979-2014 Mustangs and is a modular system that can be added in stages, or all at once.  1979-2004 kits include Super Subs, Jacking Rails, and the Extreme Matrix Brace.  2005-2014 kits include Jacking Rails and the Extreme Matrix Brace, tying the components to the factory frame rails.  All components are plated in silver zinc, and backed by a lifetime warranty on workmanship and materials.
