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.

UMI Performance boxed weld-in subframe connectors are necessary chassis upgrades when racing and hard driving habits are present. UMI Performance boxed weld-in subframe connectors greatly improve your car's handling ability, while reducing T-top squeaks, dash rattles, and quarter-panel flexing. Subframe connectors essentially tie the front and rear steel subframes together, resulting in a stiffened and strengthened chassis, allowing for better weight transfer and improved traction when launching. When strength is a concern, square tubing has greater torsion resistance over tubular designs. They will work with all aftermarket exhaust systems and will not affect ground clearance. Their weld-in style requires no bolts to tighten and offer less chance of flex when compared with bolt-in types.
