Achieving the Perfect Flush Fitment

BMW M performance vehicles are renowned for their precision engineering, powerful performance, and distinctive design. One of the popular modifications among BMW enthusiasts is the use of wheel spacers. Wheel spacers can enhance both the aesthetics and handling of your vehicle by pushing the wheels outwards for a flush fitment. This guide will help you choose the correct size spacers for your BMW M to achieve that perfect look and performance.

What Are Wheel Spacers?

Wheel spacers are components installed between the wheel hub and the wheel itself. They effectively push the wheel outwards, increasing the track width of the vehicle. This modification can improve the stance of the car, provide better stability, and accommodate larger brake kits.

Benefits of Wheel Spacers

1. Enhanced Aesthetics: Achieving a flush fitment where the wheels are perfectly aligned with the fenders can dramatically improve the vehicle's appearance.
2. Improved Handling: By widening the track, spacers can offer better cornering stability and reduced body roll.
3. Brake Clearance: Spacers can create additional space for larger brake kits.

Choosing the Correct Size Spacers

Selecting the right size wheel spacers is crucial for ensuring optimal fitment and performance. Here’s a detailed guideline for both F and G series BMW M models:
