Show original supplier description
The ECS Tuning Wheel Spacer & Bolt Kit provides a 12.5mm offset to enhance your BMW's appearance and handling. These spacers are crafted from 6061-T6 aircraft-grade aluminum, precision CNC-machined in-house to exacting standards. ECS has carefully evaluated OEM hub flange and wheel bore tolerances to ensure precise fitment with minimal clearance, promoting vibration-free operation. Included in this kit are extended wheel bolts specifically matched to the spacers, eliminating guesswork for correct fitment. These bolts are designed to meet the strict ISO 898 class 10.9 mechanical and physical properties, which govern material properties, hardening, tempering, and proof load strength. The fasteners have undergone laboratory testing to verify compliance with these requirements. Wheel spacers offset wheels to improve vehicle aesthetics and handling. They install between the wheel and hub, pushing wheels outward for a wider stance. This helps perfect wheel fitment, achieve a flush appearance, or gain necessary clearance from braking or suspension components. The product details indicate that this kit fits a wide range of BMW models, including E23, E24, E28, E30 M3, E31, E32, E34, E36, and E38 chassis, among others. However, specific fitment should always be confirmed using the vehicle selector.
