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
On a homologated racing or prototype hub, there's no aftermarket offset range to reference — there's no enthusiast community running this exact hub pattern, because every wheel on a build like this is application-specific. Forging still matters here, arguably more than on a road car: less rotational mass translates directly into faster acceleration, shorter braking distances and quicker direction changes, without touching the homologated hub geometry the racing series or one-off build already specifies.
The Porsche 718 Cayman GT4 Clubsport runs F 18x9.0J ET61 / R 18x10.5J ET50 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.

The 2019 Porsche 718 Cayman GT4 Clubsport (GT / Cup Race Car) runs F 18x9.0J ET61 / R 18x10.5J ET50 on a 5*130 homologated bolt pattern. 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 718 Cayman GT4 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 is homologated to a specific racing application. 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 718 Cayman GT4 Clubsport use a standard bolt pattern?
No. It uses a 5*130 homologated bolt pattern, not a retail lug-bolt pattern, so off-the-shelf aftermarket road wheels do not apply.
Can ANKUSI build wheels for a Porsche 718 Cayman GT4 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.
