CTS Turbo Alloy Wheel Spacers Hubcentric Shims BMW 5x112 5x100 66.6 15mm 20mm is a set of wheel spacers designed for precise widening of the wheel track in vehicles with BMW mounting. Thanks to the hubcentric design and compatibility with popular bolt patterns, these components allow for stable wheel installation and improved vehicle handling. This product, from the Wheel Spacers and Centering Rings category, provides a functional solution for suspension and wheel geometry modifications.

Purpose and function of the spacers

The wheel spacers in this set are designed for use on both the front and rear axles of the vehicle, which facilitates consistent adjustment of the track width and the car's appearance. The hubcentric design ensures the wheel rests on the hub rather than just on the bolts, which reduces the risk of vibration and improves stability at higher speeds. Using these spacers allows for:

• achieving a more flush fitment within the wheel arches while maintaining proper wheel geometry,
• increasing clearance between the wheel and suspension or brake system components,
• more even load distribution on the hub.

Construction and mounting parameters

The CTS Turbo set is based on an alloy construction, which promotes a favorable strength-to-weight ratio. The spacers are compatible with 5x112 and 5x100 bolt patterns, allowing for use in a wide range of models with BMW mounting and wheels using these standards. The varied thicknesses in the set allow for selecting a configuration tailored to a specific project – from a subtle widening to a more pronounced change in wheel track.

Hubcentric shims ensure the wheel is centered on the hub, which is particularly important at higher speeds and in cars with stiffer suspension. A properly selected center bore diameter allows for correct axial load transfer and reduces the risk of lateral runout.

Application on the front and rear axles

The ability to mount them on the front and rear of the vehicle provides configuration flexibility – you can use the same set on both axles or choose different thicknesses for the front and rear to achieve the desired handling characteristics. In practice, this allows you to:

• adjust the track width to the specifics of the suspension and tires,
• reduce the "sunken" wheel effect after changing size or offset (ET),
• achieve a visually and technically consistent wheel setup across the entire vehicle.

This solution is particularly useful when installing aftermarket wheels, where it is necessary to correct the offset to avoid rubbing against brake calipers or suspension components.

Characteristics of the pre-owned product

The presented set comes from the secondary market, which allows for reducing modification costs while maintaining the functionality of the component. Spacers of this type, when properly installed and used, retain their performance properties, which is why they are often chosen as an economical solution when changing wheels or suspension configurations. Before installation, a standard inspection of the contact surfaces and the threads of the mounting bolts on the vehicle is recommended.
