Your wheels look great until you see them from the rear three-quarter and notice the gap between the tire sidewall and the fender lip. Ten millimeters per side pulls the wheel out toward the fender without buying new wheels or changing tire sizes.
Dinan 10mm wheel spacers (part number D210-2027) are machined for the BMW 5x112 bolt pattern and 66.5mm center bore used across the G-chassis lineup. They push each wheel 10mm further from the hub, widening your track for a fuller stance and extra room around big brake calipers. You get a pair, enough for one axle.
Why Dinan 10mm Wheel Spacers Are Worth It
A spacer that does not center properly on the hub shows up as vibration at highway speed. These are CNC-machined from billet 6061 aluminum and anodized black, with a 66.5mm bore cut to BMW's G-chassis hub diameter so the spacer seats on the hub itself instead of floating on the studs.
The bigger question with any spacer is bolts. Your factory wheel bolts are sized for wheel-to-hub contact only, so adding 10mm means you need bolts 10mm longer to keep full thread engagement. Dinan calls out its 40mm M14x1.25 cone seat lug bolts for this spacer, which takes the guesswork out of it. Order those alongside and you are ready to bolt up.
What's Included
- 2 x Dinan 10mm wheel spacers, 5x112, 66.5mm center bore
Lug bolts are not included. Dinan's matching bolt for this spacer is the M14x1.25 cone seat 40mm set (sold separately).

- 5x112 bolt pattern with 66.5mm center bore for BMW G-chassis hubs
- CNC-machined billet 6061 aluminum
- Weight-saving design
- Black anodized finish
- Sold as a pair (one axle)
- Designed to pair with Dinan 40mm M14x1.25 cone seat lug bolts
Vehicle Fitment
Dinan's application guide specifies this 5x112, 66.5mm center bore spacer (used with M14x1.25 bolts) for:
- BMW G-Chassis (5x112 / M14x1.25)
- BMW F9x M5 / M8 and F48 X1 / F39 X2 (exceptions that use the G-chassis fitment of 5x112 with M14x1.25 bolts)
Not for E-chassis BMWs (5x120 / M12x1.5) or other F-chassis BMWs (5x120 / M14x1.25). Contact us before ordering if your car is not covered above.
Installation Notes
A straightforward bolt-on job with a jack, jack stands and a torque wrench. The critical step is using longer bolts: Dinan matches its 40mm M14x1.25 cone seat bolts to 10mm and 12mm spacers. Confirm your wheels use a cone seat before ordering bolts, and check tire-to-fender clearance at full steering lock, especially on staggered or aggressive-offset setups.
- Loosen the wheel bolts, raise the car and support it on jack stands.
- Remove the wheel and clean any rust or debris from the hub face.
- Slide the spacer over the hub pilot so it sits flush against the hub face.
- Mount the wheel and thread in the 40mm lug bolts by hand.
- Snug the bolts in a star pattern, lower the car and torque to your BMW's factory wheel bolt specification.
- Recheck torque after the first short drive.
