The 3rd Gen Camaro and Firebird are known for having a weak and flexible steering box area. To address flex and improve handling, a steering brace, also known as the Wonder Bar from QA1, is available. These tubular components bolt directly above the front sway bar, tying the front subframes together. Installing a QA1 Wonder Bar helps stiffen the front frame, reducing stress on this weak point. This translates to improved steering response to your vehicle with benefits like sharper handling, improved cornering, and overall better vehicle performance. Features and benefits: * Tubular construction strengthens the front chassis * Thoughtful design—the QA1 Wonder Bar installs cleanly between the sway bar and frame rails, maintaining a factory appearance without compromising ground clearance * Bolt-in installation makes the upgrade hassle-free Fitment Notes: Please be aware that 1982-1984 cars may need to slot existing mounting holes.
