Hub-centric Wheel Spacers

What are hub-centric wheel spacers, and when are they needed?

A hub-centric spacer sits directly on the vehicle’s hub and is machined with its own precise centre bore, so it locates on the hub in exactly the same way the wheel normally would — then the wheel locates on the spacer. This keeps everything running true, rather than relying on the wheel bolts to hold the assembly central. Hub-centric spacers are typically needed when:

• Fitting wider wheels or tyres that need extra clearance from the arch, suspension, or brake components
• Correcting stance or track width for improved handling and cornering stability
• Restoring a staggered fitment where front and rear wheels sit at different offsets
• Replacing bore-centric spacers that have caused vibration or an insecure fit

How Our Hub-centric Spacer Process Works

1. Measurement — We confirm the vehicle’s hub diameter, wheel bolt pattern, and the additional offset required.
2. Material Selection — Spacers are machined from high-grade aluminium alloy, sized correctly for the load and application.
3. CNC Machining — Each spacer is precision turned to a hub-centric bore and bolt pattern on calibrated CNC equipment, ensuring a true, tight-tolerance fit.
4. Fitment Check — Spacers are test-fitted to confirm secure, centred location on the hub before sign-off.

Why Hub-centric Fitment Matters

A bore-centric spacer — one that relies on the wheel bolts to hold it central — can shift slightly under load, leading to vibration and uneven wear. Hub-centric spacers avoid this. Correct hub-centric fitment delivers:

• Vibration-Free Running — The spacer and wheel are both centred by the hub, not the bolts, for smooth running at speed.
• Reduced Stress on Wheel Bolts — Bolts clamp the assembly rather than positioning it, reducing wear and the risk of them working loose.
• Improved Handling and Stability — A correctly widened track can improve cornering grip and overall vehicle stability.

Commonly Paired With

Hub-centric spacers are often supplied alongside other wheel fitment work:

• Spigot Rings for Hubcentric Fitment — Used where a wheel’s own centre bore also needs bridging to the hub.
• Offset Adjustments for Alloy Wheels — Achieving a specific stance without altering the wheel itself.
• Center Bore Modifications — Where a wheel needs its centre bore machined to accept the spacer and hub correctly.

Built on Precision Engineering Experience

TT Precision Engineering brings decades of CNC machining experience to every spacer we produce. Each one is turned to calibrated tolerances so the finished fit is secure, accurate, and vibration-free — the same standard of accuracy we apply across our wider wheel machining and precision engineering work.

Frequently Asked Questions

What is a hub-centric wheel spacer? A hub-centric wheel spacer is a precision-machined disc fitted between the vehicle’s hub and the wheel. It locates on the hub with its own precise bore, keeping the wheel centred while increasing offset for a wider stance.

How are hub-centric spacers different from bore-centric spacers? Hub-centric spacers are machined to locate precisely on the vehicle’s hub, so the assembly stays centred under load. Bore-centric spacers rely on the wheel bolts alone to hold them in position, which can allow slight movement and vibration over time.

Will wheel spacers affect my car’s handling? Correctly specified hub-centric spacers can improve stability and cornering grip by widening the track. Incorrect sizing or bore-centric spacers can have the opposite effect, so accurate measurement and machining are essential.

What are hub-centric spacers made from? They’re machined from high-grade aluminium alloy, sized and specified according to the vehicle, load requirements, and offset needed.

Do I need longer wheel bolts with spacers fitted? In most cases, yes — extended bolts or studs are needed to maintain a safe thread engagement once a spacer is added. We can advise on this as part of your spacer specification.

How much do hub-centric spacers cost, and how long does it take? Cost and turnaround depend on the spacer thickness, bolt pattern, and quantity required. Contact us with your vehicle and wheel details for an accurate quote and current lead time.
