Detailed Specifications & Features

Dongguan Changxinda Precision Technology Co., Ltd. is a leading CNC machining expert specializing in high-precision automotive performance components, custom wheel solutions, and motorsport-grade parts. With 18+ years of manufacturing experience, the company has established itself as a trusted partner for automotive parts manufacturers, custom wheel suppliers, and performance vehicle builders worldwide. This 6061-T6 aluminum performance wheel rim exemplifies the precision engineering and manufacturing excellence that defines Changxinda's capabilities, delivering a high-performance forged-style wheel for demanding automotive applications.

The performance wheel rim is a critical safety and performance component that directly impacts vehicle handling, acceleration, braking, and overall driving dynamics. This precision-engineered aluminum wheel features a sophisticated multi-spoke design that combines aesthetic appeal with structural optimization, providing maximum strength at the hub while reducing unsprung weight at the outer rim. The 5x120 bolt pattern is specifically engineered for BMW 3 Series, 4 Series, 5 Series, and M Series vehicles, ensuring perfect fitment with factory hub centers, brake clearance, and suspension geometry.

Manufactured from aerospace-grade 6061-T6 aluminum alloy using advanced CNC machining center technology, this wheel rim delivers exceptional strength-to-weight performance essential for high-performance driving. The 6061 aluminum provides an optimal balance of strength, corrosion resistance, and machinability, making it ideal for performance wheel applications where both durability and lightweight characteristics are critical. The CNC machining process enables precise production of complex three-dimensional geometry including the multi-spoke pattern, hub mounting surface, lug seat pockets, and outer rim profile in a single integrated operation.

The wheel features a precision-machined 5x120 bolt circle with five lug holes accurately positioned to ensure proper wheel centering and balanced force distribution during dynamic loading. The hub-centric mounting surface is machined to tight tolerances to ensure vibration-free operation at all speeds. The lug seat pockets are precision-machined to accommodate either conical or ball-seat lug hardware, providing secure wheel attachment under all driving conditions including hard cornering and aggressive braking.

Available in 18-inch, 19-inch, and 20-inch diameters with common widths of 8.5J, 9.5J, or 10J, this wheel accommodates a wide range of vehicle fitments and tire combinations. The multi-spoke design features optimized spoke geometry that maximizes strength while minimizing weight, with smooth transitions between the hub area, spokes, and outer rim. The careful balance between spoke count, spoke width, and spoke profile provides both structural performance and the aesthetic appeal that performance car enthusiasts demand.
