Bimecc Alloy Wheel Spacers Hubcentric Shims BMW 5x120 72.6mm 12mm SPK80 Pair

Bimecc Alloy Wheel Spacers Hubcentric Shims BMW 5x120 72.6mm 12mm are precisely manufactured, used spacers designed for wheels with a 5x120 bolt pattern and a 72.6 mm center bore, providing a 12 mm track width increase per side. Thanks to their well-matched technical parameters, this product allows for more stable vehicle handling and improves the visual fitment of wheels within the wheel arches while maintaining high functionality. This is a solution for users looking for a balanced compromise between aesthetics and driving dynamics.

Purpose and key technical parameters

These wheel spacers are designed for the typical BMW wheel mounting configuration with a 5x120 bolt pattern and a 72.6 mm hub diameter. The 12 mm thickness allows for a noticeable yet controlled offset of the wheel from the hub, which helps to better fill the wheel arch without excessive interference with the suspension geometry. Such components are particularly valued when installing wheels with factory specifications, where a visual improvement and a slight widening of the track width are desired.

Benefits of using wheel spacers

Using spacers with these parameters can bring a number of practical benefits in daily vehicle operation:

• more even filling of the wheel arches while retaining factory wheels,
• potential increase in stability at higher speeds due to a wider track width,
• the ability to better fit wheels with different offsets (ET) to a specific body,
• visual improvement of the car's stance through a wider wheel offset. Properly selected spacers from the Spacers and centering rings group are often used both in daily driven cars and in projects focused on more dynamic driving, where predictable suspension behavior is essential.

Product characteristics and fitment

The model designated as SPK80 comes from the manufacturer Bimecc, known for producing wheel mounting components. The product is marked as used, which in practice means that before installation, it is worth verifying the condition of the contact surfaces and the cleanliness of the mounting holes to ensure proper seating on the hub and wheels. Spacers with these parameters are particularly useful for:

• correcting wheel fitment after changing width or ET,
• installing wheel sets with similar, but not perfect, parameters compared to factory ones,
• achieving a more "pushed out" wheel look without the need to replace the entire set of wheels. Due to the specific dimensions, it is recommended to carefully compare the hub and wheel parameters of your specific BMW model before purchase to ensure full mechanical compatibility and safe operation of the running gear.

Professional application and assembly aspects

In a workshop environment, spacers with a fixed thickness of 12 mm are often chosen as a solution that allows for a reasonable safety margin while providing a noticeable widening of the track. During installation, pay attention to:

• thorough cleaning of the hub and wheel surfaces from corrosion and dirt,
• checking the length of the bolts or studs after applying the spacer,
• the correct sequence and torque for tightening according to the vehicle manufacturer's recommendations. This approach minimizes the risk of wheel wobble, uneven tire wear, and unwanted vibrations while driving. A used component, properly prepared for installation, can still provide stable and predictable behavior of the running gear.

More about used OEM parts

When choosing used wheel mounting components, it is worth considering not only the technical parameters but also the availability of parts and the repair lead time.
