COBB Performance Series ST-01 Wheel 18x9.5 ET40 5x114.3 - Silver cobb82W605-SL

Upgrade your vehicle's appearance and performance with the COBB Tuning Performance Series ST-01 Wheel in Silver. Featuring a classic six-spoke design with modern COBB styling, this performance wheel combines an aggressive appearance with flow-formed aluminum construction for a lightweight, durable alternative to traditional cast wheels.

Manufactured using advanced flow-forming technology, the ST-01 is designed to provide improved strength and reduced weight compared with conventional cast wheels. Reducing unsprung and rotational mass can benefit suspension response and vehicle dynamics, depending on the wheel and tire combination.

The wheel features an 18 x 9.5-inch size, +40 mm offset, and 5 x 114.3 mm bolt pattern, with a 56.1 mm hub bore. These specifications are designed primarily for compatible modern Subaru applications, including select WRX and WRX STI models. The silver finish provides a clean, timeless appearance that complements a wide range of exterior colors.

Each wheel includes a paint-matched center cap for a coordinated finish. Wheels are sold individually, allowing customers to purchase the quantity needed for their vehicle.

Manufactured by COBB Tuning, the ST-01 Performance Series wheel is an excellent option for enthusiasts seeking a balance of distinctive styling, flow-formed construction, and performance-oriented fitment.

Important Fitment Note: A matching bolt pattern alone does not guarantee fitment. Confirm brake-caliper clearance, wheel offset, hub compatibility, tire dimensions, and suspension setup before ordering. The 18 x 9.5-inch width and +40 mm offset may not suit every vehicle without additional clearance checks. Verify compatibility for vehicles outside the confirmed Subaru applications.

• Verify wheel specifications against your vehicle's factory requirements before purchase.

• Check brake-caliper clearance using the manufacturer's wheel-clearance template.

• Confirm the correct lug hardware and seating type for your vehicle.

• Ensure the wheel is properly centered on the hub and tightened to the vehicle manufacturer's torque specifications.

• Professional installation and balancing are recommended.

• Wheel fitment can vary with suspension modifications, ride height, brake upgrades, and tire selection.
