Cusco Lower Bar Suframe Honda S2000 AP1 AP2

The Cusco Rear Subframe Brace (Lower Bar) is a critical reinforcement component for enthusiasts looking to reduce unwanted flex and maximize rear-end stability under hard driving. Mounted beneath the rear subframe, this bar ties key suspension points together to maintain alignment geometry and reduce distortion during aggressive cornering, acceleration, and braking.

While the factory subframe is sufficient for street use, it lacks the torsional rigidity needed for serious performance. The Cusco rear lower brace directly addresses this by minimizing movement between mounting points, helping to preserve the intended suspension dynamics and improve rear-end feedback. The result is sharper turn-in, reduced mid-corner instability, and more confident rotation — especially when running wider tires or stiffer coilovers.

Crafted from high-tensile steel or lightweight aluminum (depending on application), the bar is finished in Cusco’s signature blue for corrosion resistance and motorsport styling. Each unit is engineered for a precise, bolt-on fit with no cutting or modification required, making it an easy and impactful upgrade.

• Reinforces rear subframe to reduce chassis flex and distortion
• Improves rear suspension geometry stability under load
• Enhances turn-in, rotation, and rear-end predictability
• Lightweight, high-strength steel or aluminum construction
• Cusco blue powder-coated finish for durability and style
• Direct bolt-on installation — no cutting, no welding

For serious drivers and track-day regulars, this lower bar serves as the backbone of a more rigid chassis, and pairs perfectly with Cusco’s full suite of undercarriage reinforcement like power braces and sway bars.
