New BIMECC Stud Conversion Kit, M12x1.5mm 20pc 68/75/82/90mm Length Studs and 20pc Open Nuts to Suit (Optional Lock Nuts)

Bimecc Wheel Stud Conversion Kits are perfect for easily fitting various spacer sizes without having to change the bolts each time. They also simplify wheel installation.

This kit includes 20 black M12x1.5 studs and 20 open-ended 17mm black hex nuts to suit your needs.

We offer four different stud lengths, allowing you to select the ideal size for your front and rear axles. This provides the flexibility to customize your setup exactly how you want it.

The listed lengths refer to the total stud length. Each allows 20mm into the hub, with a 5mm space between threads, and the remaining length protruding from the hub for spacers and the wheel to sit on:

- **68mm:** suitable for spacers up to 8mm  
- **75mm:** suitable for spacers up to 15mm  
- **82mm:** suitable for spacers up to 20mm  
- **90mm:** suitable for spacers up to 25mm

Optional locking nuts can be added. If selected, you'll receive 16 open-ended 17mm hex nuts and 4 locking nuts.

This M12x1.5mm fitment is compatible with earlier BMW models, generally pre-2012 E-series vehicles, such as:

- E8X 1 Series  
- E36, E46, E9X 3 Series  
- E12, E28, E34, E60 5 Series  
- E63/4 6 Series  
- E38 7 Series (note: not compatible with E65, which uses M14x1.5mm)  
- E31 8 Series  
- Z3, E86, E89 Z4

The stud kit may also fit other vehicles with M12x1.5 bolts and wheels that use a standard taper.
