When shopping for wheel spacers, you’ll often see the terms hub-centric and non-hub-centric. But what do they mean — and why does it matter? The difference comes down to how the wheel is centred on the hub, and it makes a huge difference in ride quality, safety, and long-term reliability.
What Does “Hub-Centric” Mean?
A hub-centric spacer is designed with a centre bore that perfectly matches the diameter of your car’s hub. This allows the wheel to sit directly on the hub lip, keeping it perfectly centred.
The hub supports the weight of the car, while the wheel bolts simply hold it in place. This is how the factory intended every wheel to fit — and it’s exactly how Killer Offset, Demon, and Bimecc hub-centric spacers are engineered.
What Is a Non-Hub-Centric Spacer?
A non-hub-centric spacer (sometimes called a “flat” or “universal” spacer) doesn’t have a centre bore to match your hub. Instead, the wheel relies only on the bolts to stay centred.
This small difference can lead to wheel wobble, vibration, or uneven load on the hub bearings, especially at higher speeds.
Why Hub-Centric Spacers Are Safer
Because hub-centric spacers mimic the factory wheel fitment, they keep your wheels perfectly aligned and balanced. The hub takes the weight, not the bolts — meaning no vibration, no stress on threads, and no risk of wheel movement.
Every Killer Offset, Demon, and Bimecc spacer sold by Stanced UK is fully hub-centric, CNC-machined from 6061-T6 aluminium alloy for precise fit and strength.
When Non-Hub-Centric Spacers Are Used
Non-hub-centric spacers are generally only used for very small thicknesses (around 3mm–5mm) where the spacer is too thin to include a full centre bore lip. Even then, they should only be used for minor clearance adjustments, and only with perfect bolt torque and alignment.
The Bottom Line
If you’re looking for improved stance, handling, and peace of mind, always choose hub-centric spacers. They’re the only type that maintain proper wheel alignment and balance — and the only type we recommend for daily, show, or performance cars.
