Aston Martin DB11, DB12 & DBX Hubcentric Wheel Spacers – 5×128 PCD, 75.1mm Bore | UK Made | Brightstone Engineering

Precision CNC-machined Aston Martin wheel spacers for the DB11, DB12, DBX and DBX707. These hubcentric track widening spacers are engineered in the UK from aerospace-grade 6082-T6 billet aluminium to the exact 5×128 (5x128) PCD and 75.1mm centre bore specification — delivering a measurably wider stance, corrected wheel offset, and a flush fitment that fills the arches without compromise to refinement or safety.

Every pair is bored to exactly 75.1mm to engage the hub register precisely, eliminating vibration at source. Supplied with extended wheel bolts — extended M14×1.5 ball-seat hardware matched to Aston Martin's OEM fastener specification.

Available in 15mm, 20mm, and 25mm. Choose from our full range of Aston Martin wheel spacers to suit your build. For a subtle, OEM-plus correction to wheel offset choose 15mm. For a more pronounced stance change on the DB11 Volante, DB12 Volante or DBX707 choose 20mm or 25mm.

Fitment:

These Aston Martin 5×128 (5x128) wheel spacers are designed specifically for vehicles with 5×128 PCD (pitch circle diameter) and 75.1mm hub bore (centre bore), using M14×1.5 ball-seat wheel bolts. DB11 wheel spacers, DB12 wheel spacers, DBX wheel spacers and DBX707 wheel spacers are all covered by this kit — spanning Aston Martin's full grand tourer and SUV range built at Gaydon, including V8, V12, AMR and Volante variants.

Not compatible with the DBS Superleggera, which uses a different 5×114.3 bolt pattern, or with models using stud-and-nut fastener systems — including the Rapide and Vanquish II (M14×2.0 nuts). Contact us if unsure.

• Aston Martin DB11 — V8 and V12, Coupé and Volante (2016–2023)
• Aston Martin DB12 — V8, Coupé and Volante (2023–present)
• Aston Martin DBX — all variants (2020–present)
• Aston Martin DBX707 — (2022–present)

All models above use 5×128 PCD, 75.1mm centre bore and M14×1.5 ball-seat wheel bolts. Always verify your exact specification and check the bolts against your car before fitting.

Not compatible with Aston Martin models using stud-and-nut fastener systems — including the Rapide and Vanquish II, which use M14×2.0 nuts. If you're unsure which fastener system your car uses, contact us before ordering.

Installation:

Professional fitting recommended. Before fitting, you must check the bolts against your car.

1. Measure a bolt from your car. Remove one of your existing wheel bolts and measure it. Measure the threaded part only — from where the thread starts to the tip, not including the head. The threaded part of the new bolt must be longer than this by the thickness of the spacer you've bought: for example, a bolt with 28mm of thread used with a 20mm spacer needs a bolt with 48mm of thread.
2. Compare it with the bolts you'll be fitting — whether supplied by us or sourced yourself. Thread size, pitch, seat type and head must match your original.
   What is the seat? It's the shape of the underside of the bolt head — the part that presses against your wheel. It's usually either cone-shaped (called "conical" or "60° taper") or rounded (called "ball" or "radius"). It must match the shape of the bolt holes in your wheel: the wrong shape only touches the wheel on a thin edge and can work loose. Simple check: hold your old bolt next to the new one — the underside of the heads should be the same shape.
3. Check the extra length. The threaded part of the new bolt must be longer than the threaded part of your original by the thickness of the spacer you've bought.
4. Confirm thread engagement. Once fitted, every bolt must engage the hub by at least as much thread as your original bolt did without a spacer — never less.
   What is thread engagement? It's how much of the bolt's thread is actually screwed into the hub — this is what holds your wheel on. The spacer moves the wheel further out, which is why the bolt needs to be longer. Simple check: when you take out an original bolt, count how many full turns it takes to come out once it's loose. After fitting the spacer and wheel, each new bolt must take at least that many full turns to screw in by hand before its head reaches the wheel. Fewer turns means less thread holding the wheel on — do not drive the car. If a bolt stops turning before its head reaches the wheel, it may be too long or cross-threaded — don't force it. Once every bolt is in, tighten them to your vehicle manufacturer's specified torque setting using a torque wrench — check your owner's handbook or a main dealer for the correct figure for your car.
5. If anything doesn't match, do not fit them — contact us first.

We make every effort to send the correct bolts, but it is the buyer's and installer's responsibility to verify them before use.

Re-check all wheel bolts after the first 50–100 miles.

Frequently Asked Questions

Are wheel spacers safe on an Aston Martin?

Yes, provided they are hubcentric, correctly specified, and fitted with bolts you have checked against your originals and that achieve full thread engagement. A hubcentric spacer engages the hub register directly, meaning the hub — not the wheel bolts — carries the load. Our spacers are machined to OEM tolerances and supplied with correctly rated M14×1.5 ball-seat hardware for the application.

Will wheel spacers void my Aston Martin warranty?

Fitting aftermarket components can affect warranty coverage on modified parts, but it does not automatically void your entire vehicle warranty under UK consumer law. We recommend informing your Aston Martin dealer before fitting and retaining records of installation. If your car is out of warranty this is not a concern.

What size wheel spacers should I fit to my DB11?

15mm is the most popular choice for a subtle, OEM-plus result that widens the track without altering the car's proportions noticeably. 20mm produces a more pronounced change and is better suited to cars running lowered suspension. 25mm is for buyers who want the wheel face to sit flush with or slightly proud of the arch lip.

What size wheel spacers should I fit to my DBX or DBX707?

15mm works well on standard ride height DBX models for a cleaner, more purposeful stance. The DBX707 responds well to 20mm given its wider factory arches. 25mm is suitable if you are running aftermarket wheels with a higher ET offset than standard.

Do I need to check the bolts before fitting?

Yes — and this is the buyer's and installer's responsibility. We make every effort to send the correct bolts, but vehicles vary by model year, market and previous modifications, so before fitting you must remove one of the bolts currently on your car, measure it, and confirm the bolts you'll fit match it for thread size, pitch, seat type and head, and have a threaded part longer than your original's by exactly the thickness of the spacer you've bought (measure the threaded part only, not the head). Once fitted, each bolt must engage the hub by at least as much thread as your original did without a spacer. Once fitted, tighten them to your vehicle manufacturer's specified torque setting. If anything doesn't match, don't fit them — contact us and we'll sort it out.

Do I need a wheel alignment after fitting wheel spacers?

Wheel spacers do not alter your suspension geometry or steering geometry directly, so a full alignment is not strictly required. However if your car is already at the limit of its alignment tolerances, adding track width can push it fractionally out. We recommend a check if your car has been lowered or has high mileage.

What is the difference between hubcentric and lug-centric spacers?

A hubcentric spacer has a precision-machined bore that matches your hub diameter exactly — in this case 75.1mm — so the hub itself centres the wheel and carries the lateral load. A lug-centric spacer relies on the wheel bolts to centre the wheel, which can cause vibration and places additional stress on the fasteners. All Brightstone spacers are hubcentric.

Are these spacers compatible with the DBS Superleggera or Vantage?

No. The DBS Superleggera uses a 5×114.3 bolt pattern, not 5×128. The V8 Vantage (pre-2018) uses a stud-and-nut system with M14×2.0 thread. Neither is compatible with this kit. See our full Aston Martin wheel spacer range for the correct spacer for your model.
