Do I need wheel spacers for my Porsche 911 GT2 RS Clubsport?

No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.

What's the difference between wheel offset and backspacing?

Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.

Can I run staggered wheels (different sizes front and rear) on my Porsche 911 GT2 RS Clubsport?

The Porsche 911 GT2 RS Clubsport runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.

How to Read Wheel Offset & Measurements

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.

ANKUSI Engineering Expert Advice

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 GT2 RS Clubsport runs F 18x11.5J / 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.

Porsche 911 GT2 RS Clubsport Wheel & Hub Specs

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.

The 2019 Porsche 911 GT2 RS Clubsport (GT / Cup Race Car) runs F 18x11.5J / R 18x13.0J on a centerlock racing hub. These are the factory or homologated racing specifications, not a standard retail bolt pattern.

Why We Don't Publish Generic Aftermarket Fitment for This Vehicle

The Porsche 911 GT2 RS Clubsport 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.

Custom & Motorsport Wheel Program

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.

Frequently Asked Questions

Does the Porsche 911 GT2 RS Clubsport 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 GT2 RS Clubsport?
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.
