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
The Chevrolet Corvette C8 Stingray's chassis tuning assumes a certain amount of rotational mass at each corner. Forging lets ANKUSI cut that mass while matching the factory strength rating, which sharpens turn-in and reduces the energy the brakes have to absorb — a real gain on a coupe platform, not just a styling change.
The Chevrolet Corvette C8 Stingray runs a 5*120 bolt pattern, 66.9mm center bore, and a F: 19x8.5J wheel from the factory. Our Flush Fitment reference is F 20x9.0J ET42 / R 21x11.5J ET52, which tucks the tire under the fender lip on a stock-height Chevrolet Corvette C8 Stingray. Our Maximum Aggressive reference is F 20x9.5J ET38 / R 21x12.0J ET48 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chevrolet Corvette C8 Stingray OE Wheel Specs
The 2020 Chevrolet Corvette C8 Stingray (Coupe) uses a 5*120 bolt pattern with a 66.9mm center bore. Factory wheels are F: 19x8.5J R: 20x11.0J.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Chevrolet Corvette C8 Stingray (2020) we drill the 5x120 pattern and cut the centre bore to 66.9mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Flush Fitment
For a flush look with minimal rubbing, F 20x9.0J ET42 / R 21x11.5J ET52 is the recommended starting point on a stock or mildly lowered Chevrolet Corvette C8 Stingray.
Maximum Aggressive Fitment
F 20x9.5J ET38 / R 21x12.0J ET48 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE (F): 19x8.5J ET52 → ~6.8″ backspacing
- OE (R): 20x11.0J ET64 → ~8.52″ backspacing
- Flush (F): 20x9J ET42 → ~6.65″ backspacing
- Flush (R): 21x11.5J ET52 → ~8.3″ backspacing
- Max (F): 20x9.5J ET38 → ~6.75″ backspacing
- Max (R): 21x12J ET48 → ~8.39″ backspacing
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Chevrolet spec, or want a wheel built to a custom offset for your Chevrolet Corvette C8 Stingray? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Custom Forged Wheels for the Chevrolet Corvette C8 Stingray (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, so the 5x120 pattern and the 66.9mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.
Designs we already tool for the 5x120 pattern — each one is re-cut to your sizes and offsets:

What bolt pattern (PCD) does the Chevrolet Corvette C8 Stingray use?
The 2020 Chevrolet Corvette C8 Stingray uses a 5x120 bolt pattern.
How many lug bolts does the Chevrolet Corvette C8 Stingray use?
The Chevrolet Corvette C8 Stingray uses a 5-lug bolt pattern (5x120), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Chevrolet Corvette C8 Stingray?
The Chevrolet Corvette C8 Stingray's center bore is 66.9mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
What size are the factory (stock) wheels on the Chevrolet Corvette C8 Stingray?
Factory wheels on the Chevrolet Corvette C8 Stingray are F: 19x8.5J R: 20x11.0J.
What is the biggest wheel size I can fit on my Chevrolet Corvette C8 Stingray without rubbing?
The most aggressive fitment we recommend without fender work is F 20x9.5J ET38 / R 21x12.0J ET48. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the Chevrolet Corvette C8 Stingray?
For a flush look with minimal to no rubbing, we recommend F 20x9.0J ET42 / R 21x11.5J ET52 as a starting point on a stock or mildly lowered Chevrolet Corvette C8 Stingray.
Do I need wheel spacers for my Chevrolet Corvette C8 Stingray?
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.
How do I calculate wheel backspacing for my Chevrolet Corvette C8 Stingray?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 6.65" backspacing up front and 8.3" in the rear.
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 Chevrolet Corvette C8 Stingray?
Yes — the Chevrolet Corvette C8 Stingray's factory and our recommended flush/max fitments already use staggered sizing (different width front and rear), and ANKUSI can forge matching staggered sets to your target offsets.
Vehicles With the Same Hub as the Chevrolet Corvette C8 Stingray (5x120, 66.9 mm Bore)
In our database, 161 other vehicle entries from 10 makes use exactly the same 5x120 bolt pattern and 66.9 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x120 is used by 10.3% of the vehicle pages in our English fitment guide (670 of 6,503); 24.2% of those also use a 66.9 mm center bore.
Hub-Centric Rings for a 66.9 mm Center Bore
A wheel with a center bore larger than 66.9 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 67.1 mm | 67.1 → 66.9 mm |
| 70.1 mm | 70.1 → 66.9 mm |
| 70.5 mm | 70.5 → 66.9 mm |
| 71.6 mm | 71.6 → 66.9 mm |
| 73.1 mm | 73.1 → 66.9 mm |
ANKUSI forged wheels are bored to exactly 66.9 mm for this vehicle, so no ring is needed.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M12x1.5, conical-seat lug nut.
Factory Torque Spec: 136 Nm (100 ft-lb). Covers most Chevrolet passenger cars and crossovers on M12 studs.
TPMS: TPMS (Tire Pressure Monitoring System) has been federally mandated on all new light vehicles sold in the US since the 2008 model year. If your wheels use OE-style sensors, have them transferred or cloned to the new wheels at installation.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
Bolt pattern and center bore on this page were cross-checked against at least two independent sources before publication. Last reviewed 2026-09-25. Spotted an error? Email info@ankusi.com and we will verify and correct it.
