Audi Hubcentric Wheel Spacers – 5×112 PCD, 66.6mm Bore | UK Made | Brightstone Engineering

Precision CNC-machined Audi wheel spacers for the A4, A5, A6, A7, A8, Q5, Q7, Q8 and all S and RS derivatives. 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 66.6mm 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 66.6mm to engage the hub register precisely, eliminating vibration at source. Supplied with extended M14×1.5 conical-seat wheel bolts matched to Audi's OEM fastener specification.

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

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

Compatibility / Fitment:

These Audi 5×112 (5x112) wheel spacers are designed for MLB Evo platform Audi vehicles with a 5×112 PCD (pitch circle diameter) wheel bolt pattern and 66.6mm hub bore (centre bore), supplied with M14×1.5 conical-seat extended wheel bolts. Compatible models include the A4 (B8, B9), S4, RS4, A5, S5, RS5, A6 (C7, C8), S6, RS6, A7, S7, RS7, A8 (D4, D5), S8, Q5, SQ5, Q7 (4M — 2015+), SQ7, Q8, SQ8 and Audi e-tron/Q8 e-tron — including all quattro variants where applicable.

Not compatible with A3, S3, RS3, TT, TTRS or R8 — those models use a 57.1mm hub bore and require a different spacer. Not compatible with the first-generation Q7 (4L, 2005–2015) which uses 5×130 71.6mm.

Check your PCD and centre bore before ordering. Not sure how? Contact Us.

All models above use 5×112 PCD, 66.6mm centre bore and M14×1.5 conical-seat wheel bolts. Always confirm your vehicle's exact PCD and hub bore before ordering.

Not compatible with: A3, S3, RS3, TT, TTRS or R8 — these use a 57.1mm hub bore. Not compatible with the first-generation Q7 (4L, 2005–2015) — that model uses 5×130 71.6mm PCD.

Installation Notes:

Professional fitting recommended. Torque wheel bolts to Audi's specified setting — 120Nm. Always use a calibrated torque wrench and re-check torque after 50–100 miles.

Frequently Asked Questions

Are wheel spacers safe on an Audi?

Yes, provided they are hubcentric, correctly specified, and fitted to the correct torque. 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 conical-seat 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 A4 or A5?

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. 20mm and 25mm are for buyers wanting a pronounced flush fitment, particularly on B9 A4 and F5 A5 models with wider factory arches.

What size wheel spacers should I fit to my Audi Q5, Q7 or Q8?

15mm works well on standard ride height Q5 and Q7 models for a cleaner, more planted stance. 20mm is better suited to Q8 and SQ8 models given their wider factory arches. 25mm is appropriate if you are running aftermarket wheels with a higher ET offset than standard.

What is the correct torque for Audi wheel bolts?

120Nm, tightened in a star pattern using a calibrated torque wrench. Always re-check torque after 50–100 miles following installation.

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 is already near the limit of its alignment tolerances, adding track width can push it fractionally out. We recommend a check if the 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 matching your hub diameter exactly — 66.6mm 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 A3, TT or R8?

No. The A3, S3, RS3, TT, TTRS and R8 use a 57.1mm hub bore, not 66.6mm. These spacers are designed for Audi's MLB Evo platform — A4, A5, A6, A7, A8, Q5, Q7 and Q8 with 66.6mm hub bore. Fitting a 66.6mm spacer to a 57.1mm hub would create a lug-centric fitment which is unsafe. Contact us if you are unsure which hub bore your car uses.
