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.

Scion FR-S OE Wheel Specs

The 2013 Scion FR-S (Sports Coupe) uses a 5x100 bolt pattern with a 56.1mm center bore. Factory wheels are 17x7.0J F/R.

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

Flush Fitment

For a flush look, F/R 17x7.0J ET28 is a commonly used starting point — clearance must be verified on a stock or mildly lowered Scion FR-S.

Maximum Aggressive Fitment

F/R 18x9.5J ET18 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: 17x7.0J ET48

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: 17x7.0J ET28

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: 18x9.5J ET18

Cost: ~$5,500

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

Decision Guide

What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.

What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.

How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.

Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Scion FR-S owners.

Offset & Backspacing Reference

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

OE: 17x7.0J ET48 → ~5.89″ backspacing
Flush: 17x7.0J ET28 → ~5.1″ backspacing
Max: 18x9.5J ET18 → ~5.96″ 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 Scion spec, or want a wheel built to a custom offset for your Scion FR-S? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

Frequently Asked Questions

What bolt pattern (PCD) does the Scion FR-S use?

The 2013 Scion FR-S uses a 5x100 bolt pattern.

How many lug bolts does the Scion FR-S use?

The Scion FR-S uses a 5-lug bolt pattern (5x100), so you need a 5-lug forged wheel to bolt straight on.

What is the center bore size on the Scion FR-S?

The Scion FR-S's center bore is 56.1mm. 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 Scion FR-S?

Factory wheels on the Scion FR-S are 17x7.0J F/R.

What is the biggest wheel size I can fit on my Scion FR-S without rubbing?

The most aggressive fitment we recommend without fender work is 18x9.5J at ET18 offset. 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 Scion FR-S?

For a flush look with minimal to no rubbing, we recommend 17x7.0J at ET28 offset as a starting point on a stock or mildly lowered Scion FR-S.

Do I need wheel spacers for my Scion FR-S?

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 Scion FR-S?

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 5.1" 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 Scion FR-S?

The Scion FR-S 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.
