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
Every gram of rotational mass on a supercar fights the acceleration, braking, and rotational inertia numbers the factory spent enormous engineering effort achieving. A forged wheel for the Dodge SRT Viper GTS Launch Edition holds the OE strength rating at meaningfully less weight, which is a real, measurable performance gain rather than a cosmetic one.
The Dodge SRT Viper GTS Launch Edition runs a 6x114.3 bolt pattern, 71.5mm center bore, and a F: 18x10.5J wheel from the factory. Our Flush Fitment reference is F 18x11.0J ET45 / R 19x13.5J ET52, which tucks the tire under the fender lip on a stock-height Dodge SRT Viper GTS Launch Edition. Our Maximum Aggressive reference is F 18x11.5J ET40 / R 19x14.0J ET48 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Dodge SRT Viper GTS Launch Edition OE Wheel Specs
The 2013 Dodge SRT Viper GTS Launch Edition (Supercar) uses a 6x114.3 bolt pattern with a 71.5mm center bore. Factory wheels are F: 18x10.5J R: 19x13.0J.
Why the factory spec works for most owners:
- Preserves the factory-tuned ride and steering feel
- A mainstream size for this segment, keeping tire choice wide and prices reasonable
- Leaves full clearance for the stock brakes and suspension hardware
- Keeps handling predictable and consistent in everyday conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Dodge SRT Viper GTS Launch Edition (2013) we drill the 6x114.3 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.
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 18x10.5J ET52.5 → ~7.82″ F backspacing, R 19x13.0J ET60 → ~9.36″ R backspacing
- Flush: F 18x11.0J ET45 → ~7.77″ F backspacing, R 19x13.5J ET52 → ~9.3″ R backspacing
- Max: F 18x11.5J ET40 → ~7.82″ F backspacing, R 19x14.0J ET48 → ~9.39″ 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 Dodge spec, or want a wheel built to a custom offset for your Dodge SRT Viper GTS Launch Edition? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Vehicles With the Same Hub as the Dodge SRT Viper GTS Launch Edition (6x114.3, 71.5 mm Bore)
In our database, 10 other Dodge entries use exactly the same 6x114.3 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.
6x114.3 is used by 0.5% of the vehicle pages in our English fitment guide (30 of 6,503); 36.7% of those also use a 71.5 mm center bore.
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.
Frequently Asked Questions
What bolt pattern (PCD) does the Dodge SRT Viper GTS Launch Edition use?
The 2013 Dodge SRT Viper GTS Launch Edition uses a 6x114.3 bolt pattern.
How many lug bolts does the Dodge SRT Viper GTS Launch Edition use?
The Dodge SRT Viper GTS Launch Edition uses a 6-lug bolt pattern (6x114.3), so you need a 6-lug forged wheel to bolt straight on.
What is the center bore size on the Dodge SRT Viper GTS Launch Edition?
The Dodge SRT Viper GTS Launch Edition'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 Dodge SRT Viper GTS Launch Edition?
Factory wheels on the Dodge SRT Viper GTS Launch Edition are F: 18x10.5J R: 19x13.0J.
What is the biggest wheel size I can fit on my Dodge SRT Viper GTS Launch Edition without rubbing?
The most aggressive fitment we recommend without fender work is F 18x11.5J ET40 / R 19x14.0J 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 Dodge SRT Viper GTS Launch Edition?
For a flush look with minimal to no rubbing, we recommend F 18x11.0J ET45 / R 19x13.5J ET52 as a starting point on a stock or mildly lowered Dodge SRT Viper GTS Launch Edition.
Do I need wheel spacers for my Dodge SRT Viper GTS Launch 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 Dodge SRT Viper GTS Launch 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 7.77" backspacing up front and 9.3" 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 Dodge SRT Viper GTS Launch Edition?
Yes — the Dodge SRT Viper GTS Launch 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.
