ST-01 18x9.5 ET40 5x114.3 Flow Formed Wheel

The Cobb Performance Series ST-01 wheel, presented here in a Stealth White finish, is engineered for enhanced performance and aesthetics on select Subaru models. This 18x9.5 wheel features a 5x114.3 bolt pattern and an ET40 offset, designed to complement the factory suspension geometry of the intended vehicles. Constructed using a flow-forming process, the ST-01 wheel offers superior strength and a lighter weight compared to traditional cast wheels. This manufacturing technique aligns the aluminum grain structure along the wheel barrel, resulting in a more durable component that uses less material. The 56.1mm center bore is specifically sized for a direct fit on Subaru WRX and STI models. The 18x9.5 dimensions of the ST-01 wheel allow for wider tire fitments, such as 265/35R18 or 255/35R18, which can significantly improve the vehicle's contact patch for enhanced cornering grip. This wheel is sold as a set of four and includes center caps and hardware; tires are sold separately. Cobb offers the ST-01 in seven distinct finishes to allow for customization. This wheel is designed to fit the 2015-2021 Subaru WRX and STI, as well as the 2022-2026 Subaru WRX. Cobb Tuning, established in 1999, is known for developing performance software and hardware that integrates seamlessly, offering reliable and consistent results for enthusiast vehicles.
