Includes 1, 2, or 4 spacers to suit your needs Thickness options: 3 mm, 5 mm, 8 mm, 10 mm Universal compatibility across bolt patterns: 4x100, 4x108, 4x114.3, 5x100, 5x108, 5x114.3, 5x120 Key benefits Improve driving safety: spacers increase wheelbase by 1 inch (25.4 mm), widening the wheelbase to lower the center of gravity. This arrangement helps reduce strong body vibration during speed cornering and significantly enhances grip, stability, and handling. Durable construction: forged aluminum alloy provides strong wear resistance for long lasting use. The surface has an antioxidation coating and a heat treated finish to ensure precision and stability while improving hardness and wear resistance. Greater tire clearance and stance: increases clearance to accommodate wider, larger or more traction tires. Helps your vehicle achieve a more aggressive look and enhances overall driving experience. What makes it stand out Wide compatibility: designed to fit a range of common bolt patterns (4x100, 4x108, 4x114.3, 5x100, 5x108, 5x114.3, 5x120) with multiple thickness options to match your wheel and tire goals. Practical performance improvement: aims to improve grip, stability, and handling on the road by adjusting wheel spacing without compromising fitment quality. Material and finish Forged aluminum alloy for strength and wear resistance Antioxidation coated surface with heat treated finish for improved hardness and long term stability Built for precision and reliable performance under regular driving or sport driving conditions Applications and use scenarios Daily street driving with aftermarket wheels: use to widen stance for enhanced stability and grip during cornering on highways and city roads. Performance and track days: optional spacers help achieve a more stable feel at speed by increasing wheelbase and reducing vibrations in speed cornering. Tire upgrade or fitment projects: enables the use of wider or larger tires by increasing tire clearance, while maintaining compatibility with a range of bolt patterns.
