Bentley Continental GT & Flying Spur Hubcentric Wheel Spacers – 5×112 PCD, 57.1mm Bore | UK Made | Brightstone Engineering

Product Description:

Fitment

All models above use 5×112 PCD, 57.1mm centre bore and M14×1.5 ball-seat wheel bolts. Always confirm your vehicle's exact PCD and hub bore before ordering.

Not compatible with Mk3 Continental GT (2018+), Flying Spur (2020+) or Bentley Bentayga — these models use different bolt patterns. Contact us to discuss fitment options.

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 a Bentley Continental GT?

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 — the hub carries the load, not the wheel bolts. 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 Bentley warranty?

Most Continental GT and Flying Spur models on this page are now outside their original warranty period. Fitting aftermarket components can affect warranty coverage on modified parts, but does not automatically void your entire vehicle warranty under UK consumer law. We recommend retaining installation records regardless.

What size wheel spacers should I fit to my Bentley Continental GT?

15mm is the most popular choice — it delivers a meaningful track width increase and a more planted, authoritative stance without altering the car's proportions noticeably. 20mm produces a more pronounced flush fitment and works particularly well on GT Speed and Supersports models which carry a more aggressive factory appearance.

What size wheel spacers should I fit to my Bentley Flying Spur?

15mm works well on both generations of Flying Spur, adding presence and correcting wheel offset without affecting the car's grand touring composure. 20mm suits owners wanting a more pronounced change, particularly on the second-generation Flying Spur which has a more sporting stance from factory.

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 suspension or steering geometry directly. However if your car has been lowered or is near the limit of its alignment tolerances, adding track width can push it fractionally out. We recommend a check if the car has been modified.

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

A hubcentric spacer has a precision-machined bore matching your hub diameter exactly — 57.1mm in this case — so the hub 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.

Will these fit my Bentley Bentayga or Mk3 Continental GT?

No. The Bentley Bentayga and Mk3 Continental GT (2018+) use a different bolt pattern and are not compatible with this kit. Contact us to discuss fitment options for those models.
