Mercedes Wheel Spacers.
The complete guide.
Everything you need to know before buying Mercedes wheel spacers — fitment, spacer thickness, hub lip height, AMG considerations, safety, installation and UK legal requirements.
Mercedes Wheel Spacers
Mercedes-Benz owners fit wheel spacers to improve stance, fill the arches, increase track width and create extra brake clearance. On AMG models in particular, the right spacer setup can make the car look far more purposeful without changing the wheels.
Most modern Mercedes models use a 5×112 PCD with a 66.6mm centre bore, making them suitable for vehicle-specific hubcentric wheel spacers. The key is choosing the correct thickness and checking whether your hub lip allows a 10mm hubcentric spacer to fit properly.
Brightstone Engineering Mercedes spacer kits are CNC machined in the UK from 6082-T6 aluminium and supplied with the correct extended bolts for your spacer thickness.
Mercedes Wheel Spacer Fitment
Most modern Mercedes-Benz models use a 5×112 bolt pattern and 66.6mm centre bore. This includes many C-Class, E-Class, S-Class, CLS, CLA, GLC, GLE and AMG models.
The centre bore is critical. A proper hubcentric spacer locates on the vehicle hub and provides a matching lip for the wheel to sit on. This keeps the wheel centred exactly as Mercedes intended and helps prevent vibration.
Measure Your Mercedes Hub Lip Before Ordering 10mm Spacers
This is the most important point when buying thin Mercedes wheel spacers. A 10mm hubcentric spacer can only fit correctly if your vehicle's hub lip is short enough for the spacer to sit fully flat against the hub face.
Some AMG Mercedes models have a hub lip height of around 15mm. If your hub lip is 15mm deep, a 10mm hubcentric spacer cannot sit properly because the factory hub lip is taller than the spacer itself.
In that situation, you have two sensible options:
- Use a 15mm hubcentric spacer — thick enough to clear the factory hub lip and provide a new hubcentric location for the wheel.
- Use a 5mm shim spacer — a simple flat spacer where a hubcentric lip is not required due to the low thickness.
If your Mercedes hub lip is taller than the spacer thickness, the spacer will not sit flat. Before ordering 10mm hubcentric spacers, measure the hub lip depth from the wheel mounting face to the end of the hub spigot.
Mercedes Spacer Thickness Guide
Brightstone Engineering Mercedes wheel spacers are available in 10mm, 15mm, 20mm and 25mm thicknesses. The right size depends on your wheel offset, tyre width, suspension height and the look you want to achieve.

A clean OEM+ improvement for cars with enough hub lip clearance. Always measure your hub lip before ordering 10mm hubcentric spacers.
Best for: subtle stance, minor offset correction, cars with short hub lips
The safest starting point for many Mercedes and AMG models. Provides a proper hubcentric design even where the factory hub lip is too tall for a 10mm spacer.
Best for: AMG models, OEM+ stance, safe hubcentric fitment
A stronger visual change that fills larger arches and gives the car a wider, more planted appearance. Check tyre and arch clearance carefully.
Best for: larger saloons, AMG models, rear axle setups
For cars needing a more dramatic offset correction. Best used where there is enough arch clearance and the wheel/tyre setup has been checked properly.
Best for: show stance, large arches, carefully measured setups
Popular Mercedes Spacer Setups
These are common starting points for Mercedes owners running factory wheels and standard suspension. Always check arch clearance and hub lip height before ordering.
Rear: 15–20mm
A popular OEM+ setup for improving stance without making the car look overly modified.
Rear: 15–20mm
AMG models may have taller hub lips, so 15mm is often the better hubcentric choice over 10mm.
Rear: 20mm
Larger arches suit a slightly wider setup, giving the car a more planted saloon stance.
Rear: 20mm
A strong road setup for filling the arches while maintaining sensible clearance.
Rear: 15mm
Works well for compact AMG models, but always check front arch and suspension clearance.
Rear: 15–20mm
Improves the stance of AMG GT models while retaining a clean factory-style appearance.
Rear: 20–25mm
SUVs often benefit from wider spacers to fill the larger arches and improve visual stance.

These recommendations are intended for vehicles running factory wheel widths, offsets and suspension. Cars fitted with aftermarket wheels, lowering springs or coilovers may require different spacer sizes.
Common Mercedes Wheel Spacer Mistakes
Most spacer problems are avoidable. Choose vehicle-specific Mercedes hubcentric spacers, measure your hub lip before ordering thin spacers, use the correct extended bolts and re-torque after fitting.
Bolt and Hardware Requirements for Mercedes Spacers
Mercedes wheel spacers must be used with the correct extended bolts. The required bolt length is calculated by adding the spacer thickness to the original bolt length.
For example, if your original bolt is 27mm long and you fit a 15mm spacer, the correct extended bolt length is approximately 42mm. Seat type must also match the wheel. Mercedes wheels commonly use radius seat bolts, but this should always be checked against your exact wheel.
Brightstone Mercedes spacer kits include the correct extended bolts matched to your spacer thickness, removing the guesswork from ordering hardware separately.
Are Mercedes Wheel Spacers Safe?
Yes, provided they are hubcentric, correctly machined and installed with the correct bolts. A proper Mercedes spacer locates on the 66.6mm hub and provides a matching lip for the wheel, keeping the wheel centred exactly as intended.
The bolts provide clamping force, while the hubcentric location keeps the wheel running true. Problems usually come from universal spacers, poor machining, incorrect bolt length or spacers that do not sit flat against the hub.
For Mercedes and AMG models, the main safety consideration with thin spacers is hub lip clearance. If a 10mm spacer cannot clear the factory hub lip, it should not be fitted. Use a 15mm hubcentric spacer or a 5mm shim instead.
Legal and MOT Considerations in the UK
Wheel spacers are legal in the UK when fitted correctly and when the wheels do not protrude beyond the vehicle arches. MOT issues usually arise from tyres sticking out past the bodywork, poor installation or obvious wheel security problems.
You should declare wheel spacers to your insurer as a vehicle modification. This is normally straightforward, especially when the spacers are hubcentric, UK-made and supplied with correct hardware.
