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 Challenger SRT Demon 170 runs a 5x115 bolt pattern, 71.5mm center bore, and a F 18x8.0J ET18 / R 17x11.0J ET24 wheel from the factory. Our Flush Fitment reference is F 20x9.5J ET15 / R 17x11.5J ET20, which tucks the tire under the fender lip on a stock-height Challenger SRT Demon 170. Our Maximum Aggressive reference is F 20x10.0J ET12 / R 17x12.0J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Dodge Challenger SRT Demon 170 OE Wheel Specs
The 2023 Dodge Challenger SRT Demon 170 (Coupe) uses a 5x115 bolt pattern with a 71.5mm center bore. Factory wheels are F 18x8.0J ET18 / R 17x11.0J ET24.
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 Challenger SRT Demon 170 (2023) we drill the 5x115 pattern and cut the centre bore to 71.5mm 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 20x9.5J ET15 / R 17x11.5J ET20 is the recommended starting point on a stock or mildly lowered Dodge Challenger SRT Demon 170.
Maximum Aggressive Fitment
F 20x10.0J ET12 / R 17x12.0J ET15 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): 18x8.0J ET18 → ~5.21″ backspacing
- OE (R): 17x11.0J ET24 → ~6.94″ backspacing
- Flush (F): 20x9.5J ET15 → ~5.84″ backspacing
- Flush (R): 17x11.5J ET20 → ~7.04″ backspacing
- Max (F): 20x10.0J ET12 → ~5.97″ backspacing
- Max (R): 17x12.0J ET15 → ~7.09″ backspacing
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or can’t find your exact Dodge spec, or want a wheel built to a custom offset for your Dodge Challenger SRT Demon 170? Contact ANKUSI with your bolt pattern and offset target and we’ll confirm the correct forged wheel spec for your build.
Custom Forged Wheels for the Challenger SRT Demon 170 (2023)
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 5x115 pattern and the 71.5mm 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 5x115 pattern — each one is re-cut to your sizes and offsets:
Ford Mustang / Corvette C7 Forged Wheels – Brushed Silver Multi-Spoke Beadlock (5-Lug)
Belak-Style Black / Machined 16-Spoke Beadlock Forged Drag Racing Wheels – Ford Mustang / Corvette C7 Fitment (5-Lug)
Chevrolet Camaro / Dodge Challenger Forged Wheels – Gloss Black 5-Spoke Polished Lip (5-Lug)
Ford Mustang / Chevrolet Corvette Forged Wheels – Gloss Black / Machined Multi-Spoke Deep Lip (5-Lug)Frequently Asked Questions
What bolt pattern (PCD) does the Challenger SRT Demon 170 use?
The 2023 Challenger SRT Demon 170 uses a 5x115 bolt pattern.
How many lug bolts does the Challenger SRT Demon 170 use?
The Challenger SRT Demon 170 uses a 5-lug bolt pattern (5x115), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Challenger SRT Demon 170?
The Challenger SRT Demon 170's center bore is 71.5mm. 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 Challenger SRT Demon 170?
Factory wheels on the Challenger SRT Demon 170 are F 18x8.0J ET18 / R 17x11.0J ET24.
What is the biggest wheel size I can fit on my Challenger SRT Demon 170 without rubbing?
The most aggressive fitment we recommend without fender work is F 20x10.0J ET12 / R 17x12.0J ET15. 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 Challenger SRT Demon 170?
For a flush look with minimal to no rubbing, we recommend F 20x9.5J ET15 / R 17x11.5J ET20 as a starting point on a stock or mildly lowered Challenger SRT Demon 170.
Do I need wheel spacers for my Challenger SRT Demon 170?
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 Challenger SRT Demon 170?
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 5.84" backspacing up front and 7.04" 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 Challenger SRT Demon 170?
Yes — the Challenger SRT Demon 170'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 Challenger SRT Demon 170 (5x115, 71.5 mm Bore)
In our database, 69 other vehicle entries from 5 makes use exactly the same 5x115 bolt pattern and 71.5 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.
5x115 is used by 3.2% of the vehicle pages in our English fitment guide (209 of 6,503); 33.5% of those also use a 71.5 mm center bore.
Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 18x8J | ET18 | 5.21 in (132 mm) | — | — |
| Flush | 20x9.5J | ET15 | 5.84 in (148 mm) | +16 mm | +22 mm |
| Maximum | 20x10J | ET12 | 5.97 in (152 mm) | +19 mm | +31 mm |
Hub-Centric Rings for a 71.5 mm Center Bore
A wheel with a center bore larger than 71.5 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 71.6 mm | 71.6 → 71.5 mm |
| 72.6 mm | 72.6 → 71.5 mm |
| 73.1 mm | 73.1 → 71.5 mm |
| 74.1 mm | 74.1 → 71.5 mm |
ANKUSI forged wheels are bored to exactly 71.5 mm for this vehicle, so no ring is needed.
