M14 x 1.5 Variable PCD "Wobble" Wheel Bolts with Hub Centric Spigot Rings
Variable PCD wobble bolts feature an engineered floating conical collar that allows the safe, certified fitment of alloy wheels with up to a 2mm difference in PCD (bolt circle pattern). The floating 60° conical washer seats perfectly against the wheel cavity, while the high-tensile threaded bolt enters straight into your vehicle hub without lateral bending stress or shearing force.
The most popular application for this kit is fitting genuine or aftermarket BMW alloy wheels (5x120 PCD / 72.6mm centre bore) onto Vauxhall Vivaro, Renault Trafic, Nissan Primastar & Fiat Ducato vans (5x118 PCD / 71.1mm hub). This kit includes the exact 72.6mm → 71.1mm hub centric spigot rings required to centre the wheels and eliminate high-speed steering vibration.
Vehicle & Wheel Compatibility Guide:
- Vauxhall Vivaro A (2001–2014) & Renault Trafic II (2001–2014): Hub is 5x118 PCD with a 71.1mm centre bore. Safely fits BMW 5x120 wheels using these M14x1.5 wobble bolts and the included 72.6mm → 71.1mm spigot rings.
- Nissan Primastar (2001–2014): 5x118 PCD / 71.1mm bore → fits BMW 5x120 / 72.6mm wheels.
- Fiat Ducato Light Chassis (5x118): Fits 5x120 alloy wheels.

Other 2mm PCD Variations:
- Fit 5x112 wheels (Audi / VW / Mercedes) onto 5x110 hubs (Vauxhall Astra, Vectra, Zafira / Alfa Romeo / Saab).
- Fit 5x114.3 wheels (Japanese / Ford) onto 5x112 hubs (Audi / VW / SEAT / Skoda).
- Fit 5x100 wheels onto 5x98 hubs (Alfa Romeo / Fiat).
- Note: 2014+ Vivaro B and Trafic Mk3 models switched to 5x114.3 PCD and cannot use wobble bolts with 5x120 BMW wheels because the PCD difference exceeds the 2mm safety threshold.

Frequently Asked Questions (FAQ):
Are wobble bolts safe for everyday driving and commercial vans?
Yes. Our wobble bolts are manufactured by Bimecc in Italy from Class 10.9 high-tensile steel and carry rigorous TÜV approval. The floating collar bears the full clamping force against the wheel seat perpendicular to the bolt axis, meaning there is zero bending fatigue on the bolt threads.
Do wobble bolts pass UK MOT inspections?
Yes. Wobble bolts are fully road-legal in the UK and will pass an MOT inspection provided the bolts have correct thread engagement (minimum 6 full turns / 10-12mm), correct torque, and the wheels are safely centered with the included spigot rings.
What torque setting should I use for wobble bolts?
For Vauxhall Vivaro and Renault Trafic applications, torque to 140 Nm (103 lb-ft). Always recheck bolt torque after driving approximately 50 miles.
Why are spigot rings included and required?
Wobble bolts locate and clamp the bolt circle, but they do NOT locate the center of the wheel. The vehicle's center hub spigot must support and center the wheel. The included 72.6mm → 71.1mm spigot rings ensure 100% concentric alignment, eliminating steering wheel wobble at 50-70 mph.
