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
Coupes and performance platforms are where rotational mass shows up fastest — in acceleration, in braking, and in how quickly the chassis changes direction. Forging lets us build to the same strength spec as the factory wheel at a meaningfully lower rotational weight, which is where the performance gain actually comes from, not just the visual one.
The Chevrolet Camaro 45th Anniversary Edition runs a 5x120 bolt pattern, 66.9mm center bore, and a F: 20x8.0J wheel from the factory. Our Flush Fitment reference is F 20x9.5J ET25 / R 20x10.5J ET35, which tucks the tire under the fender lip on a stock-height Chevrolet Camaro 45th Anniversary Edition. Our Maximum Aggressive reference is F 21x10.0J ET20 / R 21x11.0J ET30 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chevrolet Camaro 45th Anniversary Edition OE Wheel Specs
The 2012 Chevrolet Camaro 45th Anniversary Edition (Coupe/Convert) uses a 5x120 bolt pattern with a 66.9mm center bore. Factory wheels are F: 20x8.0J R: 20x9.0J.
Why the factory spec works for most owners:
- Balances ride comfort with everyday fuel efficiency
- A widely used size in this segment, so tire and wheel availability stays strong
- Keeps unsprung weight low for stable, predictable handling
- Maintains clearance for the factory brake calipers and suspension components
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Chevrolet Camaro 45th Anniversary Edition (2012) 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.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.
The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 20x8.0J ET35 → ~5.88″ F backspacing, R 20x9.0J ET40 → ~6.57″ R backspacing
- Flush: F 20x9.5J ET25 → ~6.23″ F backspacing, R 20x10.5J ET35 → ~7.13″ R backspacing
- Max: F 21x10.0J ET20 → ~6.29″ F backspacing, R 21x11.0J ET30 → ~7.18″ R 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 Camaro 45th Anniversary Edition? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Frequently Asked Questions
What bolt pattern (PCD) does the Chevrolet Camaro 45th Anniversary Edition use?
The 2012 Chevrolet Camaro 45th Anniversary Edition uses a 5x120 bolt pattern.
How many lug bolts does the Chevrolet Camaro 45th Anniversary Edition use?
The Chevrolet Camaro 45th Anniversary Edition 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 Camaro 45th Anniversary Edition?
The Chevrolet Camaro 45th Anniversary Edition'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 Camaro 45th Anniversary Edition?
Factory wheels on the Chevrolet Camaro 45th Anniversary Edition are F: 20x8.0J R: 20x9.0J.
What is the biggest wheel size I can fit on my Chevrolet Camaro 45th Anniversary Edition without rubbing?
The most aggressive fitment we recommend without fender work is F 21x10.0J ET20 / R 21x11.0J ET30. 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 Camaro 45th Anniversary Edition?
For a flush look with minimal to no rubbing, we recommend F 20x9.5J ET25 / R 20x10.5J ET35 as a starting point on a stock or mildly lowered Chevrolet Camaro 45th Anniversary Edition.
Do I need wheel spacers for my Chevrolet Camaro 45th Anniversary Edition?
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 Camaro 45th Anniversary Edition?
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 6.23" backspacing up front and 7.13" 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 Camaro 45th Anniversary Edition?
Yes — the Chevrolet Camaro 45th Anniversary Edition'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.
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.
