ECCPP 20mm Hub-Centric Wheel Spacers 5x120 — E46/E9x/E6x (4-Pack)

The hub-centric design is the real differentiator here. With a 72.56mm center bore machined to match BMW's hub diameter, the wheel load is carried by the hub itself rather than the studs alone. That means no vibration, no harmonic shimmy at highway speeds, and none of the stress on your wheel hardware that comes with non-hub-centric designs. The 5x120mm-to-5x120mm bolt pattern and 12x1.5 thread pitch make these a direct bolt-on fit for a wide range of BMW platforms including the E46 3-Series, E90/E92/E93, E60/E61 5-Series, E63/E64 6-Series, and select 1-Series and 7-Series models.

At 20mm of added track width per corner, the real-world effect is noticeable — wider stance, improved cornering stability, and a wheel fitment that actually fills the arch the way the body was designed to look. Installation is straightforward, but ECCPP is specific about pre-install checks: confirm you have more than 20mm of fender-to-wheel clearance, that your factory wheel studs do not protrude past the spacer face, and that your wheel center bore is at least 72.56mm. Use thread lock adhesive on the studs and torque to 70–80 ft-lbs. If your existing studs are too long, trimming may be required before fitting.
