Audi A3, S3, RS3, TT & R8 Hubcentric Wheel Spacers – 5×112 PCD, 57.1mm Bore | UK Made | Brightstone Engineering

Precision CNC-machined Audi wheel spacers for the A3, S3, RS3, TT, TTS, TTRS and R8. These hubcentric track widening spacers are engineered in the UK from aerospace-grade 6082-T6 billet aluminium to the exact 5×112 (5x112) PCD and 57.1mm centre bore specification — delivering a measurably wider stance, corrected wheel offset, and a flush fitment that fills the arches without compromise to handling or safety.

Available in 12mm, 15mm, 20mm, and 25mm. Need a custom thickness? contact us.

Important fitment note: These spacers are designed for Audi's MQB platform — A3, S3, RS3, TT and R8 with 57.1mm hub bore. They are not compatible with the A4, A5, A6, A7, A8, Q5, Q7 or Q8, which use a larger 66.6mm hub bore. Always confirm your centre bore before ordering.

Compatibility / Fitment:

These Audi 5×112 (5x112) wheel spacers are designed for MQB platform Audi vehicles with a 5×112 PCD (pitch circle diameter) wheel bolt pattern and 57.1mm hub bore (centre bore), supplied with M14×1.5 ball/radius-seat (R14) extended wheel bolts. Compatible models include the A3 (8P, 8V, 8Y), S3 (8P, 8V, 8Y), RS3 (8P, 8V, 8Y), TT (8J, 8S), TTS (8J, 8S), TTRS (8J, 8S), R8 (4S — 2015+), Q2 (GA) and Q3 (8U, F3) — including all quattro variants where applicable.

Not compatible with A4, A5, A6, A7, A8, Q5, Q7 or Q8 — those models use a 66.6mm hub bore and require a different spacer. Not compatible with the first-generation R8 (42, 2006–2015) which uses a different bolt pattern.

Check your PCD and centre bore before ordering.

If you're unsure, contact us and we'll confirm the correct fitment before you order.

All models above use 5×112 PCD, 57.1mm centre bore and M14×1.5 ball/radius-seat (R14) wheel bolts. Always confirm your vehicle's exact PCD and hub bore before ordering.

Not compatible with: A4, A5, A6, A7, A8, Q5, Q7 or Q8 — these use a 66.6mm hub bore. Not compatible with the first-generation R8 (42, 2006–2015) which uses a different bolt pattern. See our Audi 5×112 66.6mm wheel spacers for MLB Evo platform models.

Installation Notes:

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 Audi A3, TT or R8?

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/radius-seat (R14) hardware for the application.

Will wheel spacers void my Audi warranty?

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 informing your Audi dealer before fitting and retaining installation records. If your car is outside its warranty period this is not a concern.

What size wheel spacers should I fit to my Audi A3 or S3?

12mm is the most popular choice for a subtle correction to wheel offset that keeps the car looking factory-correct. 15mm produces a more noticeable track width increase and works well on cars running coilovers or lowering springs. 20mm and 25mm are for buyers wanting a pronounced flush fitment, particularly on RS3 8Y models with wider factory arches.

What size wheel spacers should I fit to my Audi TT or TTRS?

15mm works well on standard ride height TT and TTS models. The TTRS responds well to 15mm or 20mm given its wider factory arches and more aggressive stance from factory. 25mm is suitable for buyers 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 suspension or steering geometry directly, so a full alignment is not strictly required. 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 over time. All Brightstone spacers are hubcentric.

Will these fit my Audi A4, A6 or Q5?

No. The A4, A5, A6, A7, A8, Q5, Q7 and Q8 use a 66.6mm hub bore, not 57.1mm. Fitting a 57.1mm spacer to a 66.6mm hub would leave a gap between the spacer and hub, creating a lug-centric fitment which is unsafe. See our Audi 5×112 66.6mm wheel spacers for those models.
