Wheel spacers are a popular upgrade for improving stance and clearance — but will they cause you to fail your MOT test? The good news is: no, quality spacers won’t affect your MOT as long as they’re fitted correctly and your wheels remain secure, safe, and covered by the arches.
MOT and Legal Requirements
During an MOT, the tester checks for safety and roadworthiness, not whether your car uses wheel spacers. Spacers are perfectly legal in the UK, provided they don’t create dangerous conditions such as:
-
Wheel or tyre contact with bodywork or suspension components
-
Wheel studs or bolts with insufficient engagement
-
Excessive wheel poke beyond the arch
-
Vibrations caused by misalignment or poor-quality spacers
If your spacers are properly installed, balanced, and hub centric, they won’t raise any issues.
Hub Centric Fitment Is Key
The safest type of spacer is hub centric, where the wheel is centred on the hub rather than just the bolts. This maintains perfect alignment and load distribution — just like the factory setup.
Every Killer Offset, Demon, and Bimecc spacer sold by Stanced UK is fully hub centric, ensuring no wheel wobble, no vibration, and no risk of MOT failure due to poor fitment.
Avoid Cheap or Universal Spacers
Non-hub centric or low-quality spacers can cause vibration or uneven load, which might lead to failed components or unsafe wheel seating. If a tester notices obvious wheel movement or insecure fitment, that could result in a fail. Quality engineering and correct hardware eliminate these risks completely.
Wheel Arch Coverage
One area where you could fail is wheel coverage. UK regulations state that tyres must not extend beyond the outer edge of the bodywork or arch when viewed from above. If your spacers push the wheels too far out, the tester may record this as a defect. The solution is simple — choose the correct thickness to achieve a flush, not poked stance.
The Bottom Line
As long as your spacers are high quality, hub centric, and fitted with the right bolts or studs, they won’t affect your MOT. Go for proven, precision brands like Killer Offset, Demon, and Bimecc — engineered for both stance and safety.
