The 1967-69 F-body was designed in an era when high performance driving and modern tire technology weren't as prevalent. Their unibody chassis, while innovative at the time, can flex and twist under stress, particularly when cornering aggressively or accelerating hard. QA1's bolt-on subframe connectors offer a simple and effective solution to this common issue. They tackle the flex issue by increasing frame rigidity, leading to a significant improvement in handling performance—especially during cornering, acceleration, and braking. The tubular design connects the front Camaro/Firebird subframe to the rear subframe, providing additional structural support and stiffness to the chassis. Additional details: * Included solid body mounts and hardware further reduce chassis flex. Their aluminum construction offers a noise-free alternative to polyurethane. * Thoughtful design: The QA1 subframe connector contours to follow the body lines for a factory-like look without sacrificing ground clearance. * Easy bolt-in installation makes the upgrade hassle-free. * Fitment notes: Does not fit convertibles.

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.
