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 Mazda 3 TCR runs 18x10.0J F/R 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.
Mazda 3 TCR Wheel & Hub Specs
The 2020 Mazda 3 TCR (GT / Cup Race Car) runs 18x10.0J F/R on a 5*114.3 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 Mazda 3 TCR 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.
Custom Forged Wheels for the Mazda 3 TCR (2020)
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.
Frequently Asked Questions
Does the Mazda 3 TCR use a standard bolt pattern?
No. It uses a 5*114.3 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 Mazda 3 TCR?
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.
