15mm Hubcentric Wheel Spacers & Bolt Kit

The RacingLine Hubcentric Wheel Spacers & Bolt Kit offers a 15mm increase in track width, aimed at improving both the visual appeal and the driving dynamics of your vehicle. By pushing the wheels further out, these spacers help achieve a desired stance, appearing flush with the wheelarches. Additionally, they provide crucial clearance for fitting larger brake calipers or coilovers, a common need for performance-oriented vehicles. This kit is precision-machined from heat-treated aerospace aluminum 7075 T6, ensuring high strength, durability, and a significant weight saving compared to less advanced materials. The spacers are finished with black anodizing to protect against road debris and corrosion, while a special surface treatment prevents bonding to the wheel or hub. The rear mounting faces include cut-outs for easier removal, even after extensive use. A pair of spacers includes ten ultra-strong grade-12.9 carbon steel black wheel bolts. The Hubcentric design is a key feature, incorporating an alloy spigot that precisely centers the spacer on the hub. This maintains the original 57.1mm center bore, critical for correct fitment and minimizing vibration. Experts strongly recommend hubcentric spacers for performance cars due to the increased risk of imbalance with non-hubcentric designs. When ordering, it is essential to select the correct bolt seat type: Ball-Seat for OEM wheels or Tapered/Conical-seat for most aftermarket wheels. Using the correct, longer replacement bolts is crucial for safety and proper installation, and these are included with the kit.
