Fitting Porsche 911 RSR wheels? This page gives the 2017 Porsche 911 RSR bolt pattern, centre bore, factory rim size and the offset range for aftermarket and forged Porsche 911 RSR rims: the same spec sheet ANKUSI uses when machining forged wheels for this car.
Quick answer: The 2017 Porsche 911 RSR uses centre-lock hubs (one central nut per wheel).
Forged wheels for the 2017 Porsche 911 RSR, built to the offset you choose. From $220 per wheel, made to order in about 25 days.
Porsche 911 RSR (2017): F 18x12.5J / R 18x13.0J on a centerlock hub. Competition/one-off vehicle -- no aftermarket data published.
Data check: the bolt pattern and center bore on this page have not yet been confirmed by a second independent source. Measure your hub or ask us before ordering. How we verify
Built to order by ANKUSI — IATF 16949 & ISO 9001 certified forged wheel manufacturer, TÜV/SFI/VIA compliant. See our factory & certifications →
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
Competition and prototype hubs are built to a specific series' or shop's homologation rules, not to a retail bolt pattern, so there's no generic 'Flush' or 'Maximum Aggressive' range that means anything here. What forging does contribute is unsprung mass reduction at the exact same structural rating the homologated spec requires — a real, measurable gain in a discipline where every gram of rotational inertia is fought for.
The Porsche 911 RSR runs F 18x12.5J / R 18x13.0J on a homologated racing hub, not a standard retail bolt pattern. ANKUSI's motorsport program forges to this exact homologated specification rather than offering generic Flush or Maximum Aggressive references, which would be meaningless on a hub this specialized — contact us with your series or application's exact hub requirements.
Correction (2026-09-20): the centre bore figure previously shown here (71.6mm) was the road-car 911 hub specification and does not apply to this vehicle. Purpose-built Porsche Motorsport centre-lock racing hubs do not use the production hub-centric bore, so the figure has been withdrawn rather than restated. Confirm the exact hub interface with Porsche Motorsport for any build.
Correction (2026-09-20): this page was previously published as "Porsche 919 RSR". No such model exists — the name conflated the 919 Hybrid (LMP1 prototype) with the 911 RSR (GTE). The car described here is the mid-engined 2017 Porsche 911 RSR (991), whose factory specification is 12.5Jx18 ET25 front (Michelin 30/68-18) and 13Jx18 ET37 rear (Michelin 31/71-18) on centre-lock hubs — matching the figures on this page. The former URL /fitment-guide/porsche-919-rsr/ now redirects here.
The 2017 Porsche 911 RSR (GT / Cup Race Car) runs F 18x12.5J / R 18x13.0J on a centerlock racing hub. These are the factory or homologated racing specifications, not a standard retail bolt pattern.
The Porsche 911 RSR is a competition, prototype, vintage or one-off commissioned vehicle. Unlike a mass-produced road car, there is no generic enthusiast community publishing "Flush" or "Maximum Aggressive" offset ranges for it, and its hub uses a centerlock racing assembly rather than a standard lug-bolt pattern. Publishing invented offset numbers for a car like this would be misleading, so we don't.
ANKUSI forges wheels to exact motorsport specifications -- centerlock, beadlock, homologation-compliant, restoration-correct, or one-off replica builds. Contact ANKUSI with your exact hub pattern, offset and application and we will confirm whether we can build for it.
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.
We do not hold this pattern wheels on a shelf — they are forged to order, which is why any offset, width and bore combination on this page is buildable rather than limited to a stock list.
Does the Porsche 911 RSR use a standard bolt pattern?
No. It uses a centerlock racing hub, not a retail lug-bolt pattern, so off-the-shelf aftermarket road wheels do not apply.
Can ANKUSI build wheels for a Porsche 911 RSR?
Yes, on a custom-quote basis for restoration, motorsport or replica applications. Contact us with your exact specifications.
Why isn't there a Flush/Max fitment guide for this car?
Flush and Maximum Aggressive figures on our other pages come from verified enthusiast community data for mass-produced road cars. No such generic data exists for this vehicle, so we don't fabricate it.
