Spec-1 Wheels SPT-3318105BL-8MZBL SPT-33 18x10.5 Blank Matte Bronze Black Lip Wheel

The Spec-1 SPT-33 is a bold, aggressive aftermarket wheel designed for enthusiasts seeking a custom fitment solution. This wheel features an 18-inch diameter with a wide 10.5-inch width, perfect for achieving a deep concave profile and aggressive stance on performance vehicles.

Key Specifications:

• Size: 18x10.5 inches
• Bolt Pattern: Blank (universal/undrilled) - requires custom drilling for your specific vehicle's bolt pattern
• Offset: -8mm (negative offset for aggressive fitment and increased track width)
• Center Bore: 73.1mm
• Finish: Matte Bronze face with Black Lip for striking two-tone appearance
• Construction: Cast aluminum alloy for strength and lighter weight

Important Note: This wheel comes with a blank (undrilled) bolt pattern, which allows for custom drilling to match your vehicle's specific bolt configuration. Professional installation and drilling by an experienced wheel specialist is required. The negative offset design pushes the wheel outward from the hub, creating a more aggressive stance and may require fender modifications depending on your vehicle.

The SPT-33's distinctive matte bronze center paired with a black outer lip delivers a premium custom look that stands out from standard wheel finishes. Ideal for builders looking to create a unique, show-quality appearance with proper fitment customization.
