KAX 5x120 Wheel Spacers 15mm +20mm Hub Centric - Improved Fit

In this review the KAX 5x120 wheel spacers are judged for drivers who need a bolt-on solution to offset and clearance issues on BMW 5x120 cars. The single biggest reason to consider them is their hub-centric 72.56mm design and forged 6061-T6 construction, which give a precise fit and strong build for widened track and corrected offset. Installation is straightforward for anyone comfortable with basic wheel work, and the package includes nuts and a manual so buyers get what they need to fit four wheels.

Key Features

• Forged 6061-T6 aluminum: Provides aircraft-grade strength and consistent durability under typical road and weather conditions.
• Hub centric 72.56mm bore: Ensures concentric seating on compatible BMW hubs for reduced vibration compared with non hub-centric spacers.
• 15mm +20mm thickness: Widens track to correct offset and improve stance or wheel clearance for aftermarket wheels and fenders.
• M12x1.5 studs and 10.9 split nuts: High-strength hardware is supplied to secure the spacer and maintain clamping force under load.
• Recommended torque 70-80 ft/lbs: A clear torque range helps installers apply the correct preload for safe, reliable fitment.

Who It's For

This spacer set is aimed at owners of BMW models using a 5x120 bolt pattern who need a simple, robust way to push wheels out for clearance or aesthetic reasons. It is well suited to people fitting aftermarket wheels that sit too far inward, or drivers who want to widen the track for a more aggressive stance while keeping a hub-centric mount.

These spacers are not for vehicles with less than 2 in of clearance between fender and wheel or for users who cannot verify stud length; some installations may require trimming long factory studs. Buyers seeking extreme offsets or an adapter to change bolt pattern should look for a different product.

Pros & Cons

Pros

• Solid construction and feel from forged 6061-T6 material for confidence on the road.
• Hub-centric design and correct bore make for a precise fit and reduce vibration risk.
• Comes with 10.9 class split nuts and an instruction manual, easing installation.

Cons

• One customer reported scratches during installation, so careful handling and protective steps are advisable.
• May require stud trimming on some cars if factory studs extend more than the spacer thickness.

Frequently Asked Questions

Will these fit my BMW?
They fit BMW models that use a 5x120 bolt pattern and a 72.56mm hub bore; verify you have at least 2 in of fender-to-wheel clearance before purchase.

Is additional hardware required?
The kit includes 10.9 class split nuts and studs as specified, so no extra hardware is normally required for installation.

Do I need to trim my factory studs?
If factory studs are longer than the spacer thickness you may need to trim them; the product notes this and recommends checking stud length first.
