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
Most of the engineering value in a forged wheel over a cast one shows up in rotational mass, not outright strength — both can meet the same load rating, but the forged piece gets there lighter. On a sedan platform tuned for everyday balance, that weight saving is felt directly in steering response and ride quality.
The Startech Chrysler 300C ships from the factory on a 5x115 bolt pattern with a 71.5mm center bore and a 20x9J ET24 wheel. Our flush reference for the Startech Chrysler 300C is 21x9.5J ET18.; our maximum aggressive reference is 22x10J ET15. — beyond that, expect clearance issues against the fender liner without further modification.
Startech Chrysler 300C OE Wheel Specs
The Startech Chrysler 300C ships from the factory on 5x115 bolt pattern wheels with a 71.5mm center bore. The stock wheel size is 20x9J ET24, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Startech Chrysler 300C (2004) 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.

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) | 20x9J | ET24 | 5.94 in (151 mm) | — | — |
| Flush | 21x9.5J | ET18 | 5.96 in (151 mm) | 0 mm | +12 mm |
| Maximum | 22x10J | ET15 | 6.09 in (155 mm) | +4 mm | +22 mm |
Vehicles With the Same Hub as the Startech Chrysler 300C (5x115, 71.5 mm Bore)
In our database, 69 other vehicle entries from 4 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.
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 Startech Chrysler 300C use?
The 2004 Startech Chrysler 300C uses a 5x115 bolt pattern.
How many lug bolts does the Startech Chrysler 300C use?
The Startech Chrysler 300C 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 Startech Chrysler 300C?
The Startech Chrysler 300C'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 Startech Chrysler 300C?
Factory wheels on the Startech Chrysler 300C are 20x9J ET24.
What does a flush wheel fitment look like on the Startech Chrysler 300C?
For a flush look with minimal to no rubbing, we recommend 21x9.5J at ET18 offset as a starting point on a stock or mildly lowered Startech Chrysler 300C.
Do I need wheel spacers for my Startech Chrysler 300C?
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 Startech Chrysler 300C?
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 5.96" of backspacing.
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 Startech Chrysler 300C?
The Startech Chrysler 300C runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
