CorkSport’s Rear Chassis Brace Set for the 2004-2011 MazdaSpeed 3 & Mazda 3 is a direct direct bolt-on one inch diameter four bar kit that stiffens up the rear-end of your vehicle’s chassis. The bar set requires you to trim a small amount of carpet out of your cargo area and utilizes stock mounting locations.
The four bar kit installs in about an hour and a half and includes all the necessary hardware to complete the installation. It fits with all existing (three bar set available if you already have our Quick-Release Rear Chassis Brace) and future CorkSport brand parts and offers a design that will set your 3 apart from the crowd.
Features:
The CorkSport Rear Chassis Brace Set utilizes powdercoated 0.25” steel brackets that mount to factory locations on the side of your cargo area and are completely hidden behind the trunk carpet except for the bar mounting holes. The bottom mounts are small and stay close to the corner of your hatch to minimize taking up precious cargo space. The bars feature a black anodized aluminum design with our CorkSport Logo etched into the bars (the two shorter bars do not have the logo). The top bar is attached to the brackets by aircraft grade quick-release pins that allow the bar to be removed quickly and effortlessly in an event that you need to fold down your rear seats and haul a large object in your 3. The end links are threaded for full stiffness adjustablility. Turn the bar one way to stiffen the rear end, turn the bar the other way to lessen the stiffness.
Testing:
The CorkSport Rear Chassis Brace Set has been tested on our own vehicles to ensure fit, form and function. The bar set increases stiffness in the rear end by tying load points together. This results in reduced chassis flex that is a common issue with the hatch-back’s open cargo area design. We have tested the design and with the bars installed, you can expect to see a 12% decrease in rear end deflection.

As with all our CorkSport Brand Mazda Products, the Rear Chassis Brace Set ships with all the hardware you need for installation. Full color step by step installation instructions and telephone technical support are also included with your purchase.
