Belak 17x4.5 / 2.25 BS / 5x114.3 BP / Series 3 Wheel - Monoblock (Req Spacer/Extended Studs)

This Belak Series 3 wheel is constructed from a single piece of forged aluminum, a monoblock design that offers a strong yet lightweight foundation. The 17-inch diameter and 4.5-inch width are specifically chosen for applications where a narrow front wheel is beneficial, often for drag racing or weight reduction. Its 5x114.3 bolt pattern and 2.25-inch backspacing are key dimensions that determine how the wheel sits on the hub and interacts with suspension components.

The monoblock forging process starts with a solid block of aerospace-grade aluminum that is heated and then subjected to immense pressure. This process realigns the metal's grain structure, creating a wheel that is exceptionally strong and resistant to flexing under load, all while keeping rotational mass down. This particular wheel is designed to be used with a spacer and extended studs, which are necessary to ensure proper clearance and secure mounting given its specific dimensions and intended use.

When installing this wheel, remember that you will need to source appropriate wheel spacers and extended lug studs separately. These are critical for safe and correct fitment. The 2.25-inch backspacing means the wheel will sit further out than a wheel with more backspacing, so the spacer helps to center the wheel properly in the wheel well and ensure adequate brake caliper clearance.
