No More Mustang Flex - The Ultimate in Under Car Chassis Support

The Ultimate Complete Full Under-Car Chassis Support System for serious drivers, high horsepower, and hard-driven Mustangs. The Extreme Matrix Mustang Chassis Brace Kit significantly improves chassis rigidity as well as improving ride quality, traction & handling of your Mustang.

The Kenny Brown Extreme Kit maximizes the strength of your car's center pan section keeping it from twisting and flexing. The unibody of Mustangs is very flexible with a lack of much torsional rigidity. 

Kenny Brown specifically designed and engineered multiple triangulations into his Mustang Chassis Brace Kit (knowing triangles are the strongest engineering structure) to significantly reduce the flexing in the Mustang's unibody. 

Kenny added four full triangulations per side for maximum rigidity. His design creates an "extremely" strong "matrix" under-body chassis frame system; hence the name - Extreme Matrix Chassis Support Kit.                        

Brown also engineered the kit to be light-weight and heavy-duty without any loss in ground clearance through his low-profile design. One of the benefits due to its superior chassis rigidity is that it reduces squeaks and rattles - especially in convertibles.

Mustang owners are impressed with the vast improvement in ride, handling, and traction.  The kit is excellent for high horsepower Mustangs, drag racing, or hard-driving applications.  It gives a great ride quality while performance driving on the street as well. A MUST for all convertibles.

The kit includes Kenny’s exclusive Double-Cross™ Subframe Connectors, Jacking Rails, and Extreme Matrix Chassis Brace.
