Genuine OEM factory-original Porsche high-speed wheel tire valve stem support bracket (Part Number: 965-361-561-00 / 96536156100). This item is brand new old stock (NOS), uninstalled, and sealed inside its original dealer fulfillment distribution packaging.

The layout features an angled metal structure calibrated for factory-forged alloy wheels. It mounts adjacent to the valve aperture to structurally backstop the flexible rubber stem assembly against severe centrifugal loads generated during high-speed acceleration. This prevents stem distortion, bead flexing, and sudden loss of air pressure on vintage performance packages.
