• Check torque regularly, especially after tire rotations
• Ensure wheels clear brake calipers and suspension components

Hub Centric Design:

Hub centric wheel spacers are engineered to center on the vehicle's hub bore rather than relying on lug studs for centering. This design eliminates vibration and ensures proper load distribution, just like factory wheels. The 66mm hub bore matches common Nissan and Infiniti applications, providing precise fitment and smooth operation. Hub centric design is critical for wheel spacers - lug-centric spacers can cause vibration and uneven wear.

7075 Aluminum Construction:

ISC wheel spacers are CNC-machined from 7075 aluminum, a high-strength aerospace-grade alloy. This material provides exceptional strength-to-weight ratio, resisting deformation under load while keeping unsprung weight to a minimum. The precision CNC machining ensures tight tolerances and perfect fitment, while the black anodized finish provides corrosion resistance and a stealthy appearance.

25mm Thickness:

The 25mm (1 inch) thickness provides a noticeable increase in track width without being excessive. This spacing is ideal for filling wheel wells on lowered vehicles, clearing larger brake calipers, or accommodating wider wheels and tires. The 25mm thickness strikes a balance between aggressive stance and maintaining proper suspension geometry.

Wider Track Width Benefits:

Increasing track width by 50mm total (25mm per side) improves handling characteristics by increasing the moment arm for lateral forces. This translates to improved cornering stability, reduced body roll, and enhanced grip during aggressive driving. The wider stance also improves appearance by filling the wheel wells and creating a more aggressive, planted look.

Grade 10.9 Hardware:

The included M12x1.25 lug nuts are Grade 10.9 specification, providing high tensile strength for secure wheel mounting. Grade 10.9 is equivalent to SAE Grade 8, ensuring the hardware can withstand the clamping forces required for safe wheel installation. The low-profile design allows clearance in tight wheel pockets.
