Forged Aluminum Wheel Spacers with Active Cooling

The BONOSS Forged Active Cooling Hubcentric Wheel Spacers are a premium upgrade for vehicles seeking an improved stance and enhanced braking performance. Crafted from high-grade forged AL7075-T6 aluminum alloy, these spacers boast a tensile strength of ≥572 Mpa, ensuring robust durability and resistance to wear, impact, and high temperatures. A key innovation is BONOSS's patented "active cooling" technology. Integrated grooves within the spacers capture and direct airflow as the wheels rotate, actively drawing heat away from the braking system. This feature helps to maintain optimal brake temperatures, improving braking efficiency and reducing the risk of thermal exhaustion, thereby enhancing driving safety. The hubcentric design ensures a precise fit with the vehicle's hub, minimizing high-speed vibrations and promoting a stable driving experience. These wheel spacers are meticulously machined to a tolerance of 0.02mm for safety and accuracy. They are paired with high-strength ISO Grade 12.9 studs (tensile strength ≥1220 Mpa) and ISO Grade 10 lug nuts, both featuring BONOSS engraving for guaranteed quality. The spacers are available in multiple thicknesses, ranging from 15mm to 50mm, with custom sizes from 3mm to 160mm available, allowing for precise fitment and aesthetic customization. Specifically designed for vehicles with a 5x120 bolt pattern and a 64.1mm center bore, these spacers are ideal for models like the Honda Civic Type R (FK2, FK8, FL5). They are sold in pairs (2 pcs) and include necessary hardware. It is important for users to measure their fender gap and confirm the desired thickness before purchase to ensure proper fitment and clearance.
