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.

Cadillac CT5-V Blackwing F1 Collector Series OE Wheel Specs

The 2026 Cadillac CT5-V Blackwing F1 Collector Series (Sedan) uses a 5x120 bolt pattern with a 66.9mm center bore. Factory wheels are F: 19x10J R: 19x11J.

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

Flush Fitment

For a flush look with minimal rubbing, F 19x10.5J ET25 / R 19x11.5J ET40 is the recommended starting point on a stock or mildly lowered Cadillac CT5-V Blackwing F1 Collector Series.

Maximum Aggressive Fitment

F 20x10.5J ET22 / R 20x12J ET35 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Real-World Reference Cases

The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.

Case 1: Daily Driver (Factory-Style)

Profile: Everyday driving, prioritizes comfort and low running cost.

Setup: F 19x10.0J ET32 / R 19x11.0J ET45

Cost: ~$620

Outcome: Minimal visual change, ride and fuel economy essentially unaffected.

Case 2: Balanced Enthusiast (Balanced / Flush Fit)

Profile: Wants a sportier stance without sacrificing daily usability.

Setup: F 19x10.5J ET25 / R 19x11.5J ET40

Cost: ~$3,000

Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.

Case 3: Show Build (Max Aggressive)

Profile: Built primarily for shows or occasional track/show use.

Setup: F 20x10.5J ET22 / R 20x12.0J ET35

Cost: ~$5,500

Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.

Decision Guide

1
What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.
2
What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.
3
How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.
4
Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Cadillac CT5-V Blackwing F1 Collector Series owners.

Offset & Backspacing Reference

Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):

  • OE: F 19x10J ET32 → ~6.76″ F backspacing, R 19x11J ET45 → ~7.77″ R backspacing
  • Flush: F 19x10.5J ET25 → ~6.73″ F backspacing, R 19x11.5J ET40 → ~7.82″ R backspacing
  • Max: F 20x10.5J ET22 → ~6.62″ F backspacing, R 20x12J ET35 → ~7.88″ 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.

Frequently Asked Questions

What bolt pattern (PCD) does the Cadillac CT5-V Blackwing F1 Collector Series use?
The 2026 Cadillac CT5-V Blackwing F1 Collector Series uses a 5x120 bolt pattern.
How many lug bolts does the Cadillac CT5-V Blackwing F1 Collector Series use?
The Cadillac CT5-V Blackwing F1 Collector Series 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 Cadillac CT5-V Blackwing F1 Collector Series?
The Cadillac CT5-V Blackwing F1 Collector Series'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 Cadillac CT5-V Blackwing F1 Collector Series?
Factory wheels on the Cadillac CT5-V Blackwing F1 Collector Series are F: 19x10J R: 19x11J.
What is the biggest wheel size I can fit on my Cadillac CT5-V Blackwing F1 Collector Series without rubbing?
The most aggressive fitment we recommend without fender work is F 20x10.5J ET22 / R 20x12J ET35. 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 Cadillac CT5-V Blackwing F1 Collector Series?
For a flush look with minimal to no rubbing, we recommend F 19x10.5J ET25 / R 19x11.5J ET40 as a starting point on a stock or mildly lowered Cadillac CT5-V Blackwing F1 Collector Series.
Do I need wheel spacers for my Cadillac CT5-V Blackwing F1 Collector Series?
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 Cadillac CT5-V Blackwing F1 Collector Series?
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 6.73" backspacing up front and 7.82" 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 Cadillac CT5-V Blackwing F1 Collector Series?
Yes — the Cadillac CT5-V Blackwing F1 Collector Series'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.
