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
Convertibles lose some of the structural rigidity a fixed roof provides, which means the suspension and wheels end up doing more of the work to keep the chassis composed. A forged wheel keeps unsprung mass down without sacrificing the strength margin the factory built in — useful on a platform that's already managing extra flex.
The Chrysler Crossfire SRT6 Roadster runs a 5x112 bolt pattern, 66.5mm center bore, and a F: 18x7.5J wheel from the factory. Our Flush Fitment reference is F 19x8.5J ET30 / R 20x10J ET20, which tucks the tire under the fender lip on a stock-height Chrysler Crossfire SRT6 Roadster. Our Maximum Aggressive reference is F 19x9J ET25 / R 20x10.5J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chrysler Crossfire SRT6 Roadster OE Wheel Specs
The 2005 Chrysler Crossfire SRT6 Roadster (Convertible) uses a 5x112 bolt pattern with a 66.5mm center bore. Factory wheels are F: 18x7.5J R: 19x9J.
Why the factory spec works for most owners:
- Matches the chassis tuning used to help offset reduced structural rigidity
- Balances ride comfort with the sportier character typical of this body style
- Keeps unsprung weight low for stable handling
- Maintains clearance for the factory brake package and suspension components
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Chrysler Crossfire SRT6 Roadster (2005) we drill the 5x112 pattern and cut the centre bore to 66.5mm 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.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 18x7.5J ET35 → ~5.63″ F backspacing, R 19x9J ET22 → ~5.87″ R backspacing
- Flush: F 19x8.5J ET30 → ~5.93″ F backspacing, R 20x10J ET20 → ~6.29″ R backspacing
- Max: F 19x9J ET25 → ~5.98″ F backspacing, R 20x10.5J ET15 → ~6.34″ R backspacing
A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
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 Chrysler spec, or want a wheel built to a custom offset for your Chrysler Crossfire SRT6 Roadster? 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 Chrysler Crossfire SRT6 Roadster (5x112, 66.5 mm Bore)
In our database, 167 other vehicle entries from 6 makes use exactly the same 5x112 bolt pattern and 66.5 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.
5x112 is used by 21.6% of the vehicle pages in our English fitment guide (1,407 of 6,503); 11.9% of those also use a 66.5 mm center bore.
Hub-Centric Rings for a 66.5 mm Center Bore
A wheel with a center bore larger than 66.5 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 66.6 mm | 66.6 → 66.5 mm |
| 67.1 mm | 67.1 → 66.5 mm |
| 70.1 mm | 70.1 → 66.5 mm |
| 70.5 mm | 70.5 → 66.5 mm |
| 73.1 mm | 73.1 → 66.5 mm |
ANKUSI forged wheels are bored to exactly 66.5 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Chrysler Crossfire SRT6 Roadster use?
The 2005 Chrysler Crossfire SRT6 Roadster uses a 5x112 bolt pattern.
How many lug bolts does the Chrysler Crossfire SRT6 Roadster use?
The Chrysler Crossfire SRT6 Roadster uses a 5-lug bolt pattern (5x112), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Chrysler Crossfire SRT6 Roadster?
The Chrysler Crossfire SRT6 Roadster's center bore is 66.5mm. 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 Chrysler Crossfire SRT6 Roadster?
Factory wheels on the Chrysler Crossfire SRT6 Roadster are F: 18x7.5J R: 19x9J.
What is the biggest wheel size I can fit on my Chrysler Crossfire SRT6 Roadster without rubbing?
The most aggressive fitment we recommend without fender work is F 19x9J ET25 / R 20x10.5J 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 Chrysler Crossfire SRT6 Roadster?
For a flush look with minimal to no rubbing, we recommend F 19x8.5J ET30 / R 20x10J ET20 as a starting point on a stock or mildly lowered Chrysler Crossfire SRT6 Roadster.
Do I need wheel spacers for my Chrysler Crossfire SRT6 Roadster?
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 Chrysler Crossfire SRT6 Roadster?
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 5.93" backspacing up front and 6.29" 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 Chrysler Crossfire SRT6 Roadster?
Yes — the Chrysler Crossfire SRT6 Roadster'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.
