BMW G26 wheel spacers: wider track, bolts included
This pair of wheel spacers with a 5x112 bolt pattern and 66.6 mm center bore is designed for 2023 BMW 4 Series Gran Coupé G26 and BMW i4 models. Each set includes 2 wheel spacers and 10 14x1.25 seat bolts in the correct length: nothing else to order to bring the wheels flush with the wheel arches.
Why choose this wheel spacer
- 66.6 mm hub-centric design: the machined shoulder retains the original centering, preventing steering wheel vibration.
- Bolts included: 10 14x1.25 seat bolts provided, lengthened to compensate for the added thickness.
- Four thicknesses: 10 mm, 12 mm, 15 mm, and 20 mm per side, to adjust the rim offset to the millimeter.
- Two finishes: silver aluminum or black anodized with matching black bolts.
- Machined aluminum: flat and parallel faces, full contact surface against the hub and rim.
5x112 wheel spacers for BMW 4 Series and i4
The 5x112 bolt pattern combined with a 66.6 mm center bore and 14x1.25 bolts is compatible with recent BMWs, including the 4 Series G26, i4, and their G22 and G23 counterparts. A BMW wheel spacer of 10 to 15 mm remains subtle and corrects a rim that sits too far inside; at 20 mm, the visual stance changes significantly. Remember to check clearance under the wheel arch when loaded, especially if the vehicle is already fitted with wider rims or a lowering kit.

Installation and maintenance
Allow 40 minutes for both wheels. Raise the vehicle on jack stands, remove the wheel, clean the hub mounting surface with a brass brush, position the spacer, then reinstall the wheel using the included bolts. Tighten in a star pattern to the manufacturer's recommended torque using a torque wrench and recheck the tightness after 50 to 100 km. Compatibility must be checked before installation depending on the model: check the bolt pattern, center bore, and original bolt thread.
Frequently asked questions
Are wheel spacers allowed on public roads?
In France, any modification to the track must remain compliant with the vehicle's type approval. Check your exact situation before driving on public roads.
Do you need longer bolts with spacers?
Yes, and they are included: the 10 14x1.25 bolts provided compensate for the added thickness to maintain the required thread engagement.
Do you need hub-centric spacers?
This is highly recommended. The machined 66.6 mm centering here prevents the vibrations caused by simply drilled models.
How many millimeters should you choose?
10 to 12 mm to correct a slight inward offset, 15 mm for a flush-with-the-arch look, 20 mm for a pronounced widening — to be confirmed according to the width and offset of your rims.
Can you install spacers only at the rear?
Technically yes, and this is common to correct a more inward rear offset. The set contains enough to equip a complete axle.
Two spacers, ten bolts in the correct length, and a track that finally matches the width of the arches.
