What is the Subaru stud pattern?
Subaru's standard lug pattern is 5x100: five lug holes on a 100 mm circle, with a typical center bore around 56.1 mm. This configuration covers most modern Subaru models, but always verify your exact year and trim for any exceptions.
In this article, we explain what that lug pattern means for wheel fitment, how to confirm your vehicle's precise specifications, and what to consider when shopping for wheels or adapters.
Core measurements you should know
These data points define Subaru’s common lug pattern and are the starting point when comparing wheels or aftermarket components.
- 5x100 bolt pattern: 5 lug holes on a 100 mm diameter bolt circle.
- Center bore: typically about 56.1 mm across most Subaru models.
- Stock wheel offset: commonly in the +40 to +50 mm range, varying by model and generation.
The exact values can vary by model and year, so always confirm the specific spec for your vehicle before purchasing wheels.
Variations and how to verify your exact pattern
While 5x100 is the standard for the vast majority of Subarus, regional versions or older generations can differ. Verifying your exact lug pattern ensures you don’t run into fitment issues when upgrading wheels.
- Check the owner's manual or official Subaru specifications for your model/year to confirm the lug pattern and center bore.
- Measure the bolt circle diameter if needed: measure the distance between the centers of two opposite lug holes.
- Count the lug holes to confirm the pattern (most Subarus use 5 bolts, but some aftermarket wheels or rare trims may vary).
- Verify the center bore size; if a wheel has a smaller bore than the hub, you may need hub rings, but ensure compatibility and safety before use.
- Consult a dealer or reputable wheel retailer if you’re unsure to avoid mismatched fitment.
In practice, the 5x100 pattern is the baseline for Subaru wheel compatibility, and most factory and aftermarket wheels marketed for Subaru will use this pattern. Always confirm for your exact model and year.
Summary
The Subaru lug pattern you’re most likely to encounter is 5x100 with a center bore around 56.1 mm. This pattern covers the majority of current models, including Impreza, Forester, Outback, Crosstrek, and BRZ/86, but always verify your specific year and trim. When in doubt, consult the owner’s manual or a Subaru dealer to ensure wheel compatibility before purchasing.
