Wheel Stud BMW Conversion Kit M12x1.5 – Black – 20 Studs + 20 Nuts

This Racing Wheel Stud Conversion Kit M12x1.5 is the perfect upgrade for BMW drivers who want to improve how their wheels are mounted. The kit replaces the original wheel bolts with high-quality wheel studs and wheel nuts, giving you a stronger, safer and more user-friendly way to fit your wheels.

In motorsport, a stud conversion is practically standard. Many BMW race cars use studs instead of wheel bolts because they are more reliable and make wheel changes considerably faster. This upgrade also offers plenty of advantages for road use.

Once the studs have been fitted, they stay permanently in the wheel hub. When changing wheels, you only need to remove the lug nuts (wheel nuts). This lets you simply slide the wheel onto the studs without having to line up the holes of the wheel, spacers and hub at the same time.

Advantages of a Wheel Stud Conversion

• Faster wheel changes – ideal for track days and maintenance

• Stronger fastening than traditional wheel bolts

• Less wear on the threads of the wheel hub

• Easier wheel fitting

• Suitable for use with wheel spacers

Thanks to the extended studs, you can use different spacer thicknesses without having to buy new wheel bolts each time. These studs are suitable for spacers of 3 mm, 5 mm, 10 mm and 12 mm, but can also be used without a spacer.

Kit contents

• 20x black wheel studs (M12x1.5)

• 20x black wheel nuts (lug nuts)

Fitting

Installation is straightforward:

1. Screw the studs into the wheel hub until they are fully seated.

2. Use a 5.5 mm Allen key to speed up fitting.

3. Use red Loctite or a comparable threadlocker to prevent loosening.

4. Tighten the studs to a maximum of 40 Nm.

5. The wheel nuts can then be tightened to the standard BMW torque of 80–88 ft-lbs.
