What is the bolt pattern on a Subaru Impreza?
The bolt pattern for most Subaru Impreza models is 5x100, meaning five lug holes arranged on a 100 mm circle.
Understanding this pattern helps owners and shoppers ensure wheels and braking components fit correctly. The following article explains what that means, how to confirm it on your car, and what to consider when replacing wheels.
Bolt pattern basics
The bolt pattern, also called PCD (pitch circle diameter), specifies how many lug holes a wheel has and the diameter of the circle those holes lie on. For the Subaru Impreza, the standard configuration is five lugs on a 100 mm circle (5x100). This pattern is shared across most modern Subaru models and underpins wheel compatibility with a wide range of aftermarket options.
Generations and consistency
Subaru has kept the 5x100 pattern across the Impreza line through multiple generations and market variants. As of model year 2024/2025, that standard remains in place, but you should verify with the exact year and market to account for any regional exceptions or special editions.
How to confirm the bolt pattern on your Impreza
To verify the bolt pattern on your vehicle, you can use a few practical checks. Start with the official documentation, then confirm on the wheel itself by counting lug holes and measuring the bolt circle.
- Check the owner's manual or Subaru official parts catalog for your model year’s wheel specifications.
- Inspect the wheel hub for lug holes; five holes indicate a 5-lug pattern.
- Measure the bolt circle diameter: from the center of one lug hole to the center of the opposite lug hole across the wheel; a measurement near 100 mm confirms 5x100.
- Check the center bore size and note whether hub-centric rings are needed for aftermarket wheels. Subarus typically have a center bore around 56.1 mm.
- When in doubt, bring a wheel or the vehicle’s paperwork to a tire shop or use a reputable online catalog to cross-check against your year and market.
Accurate verification helps prevent mismatches that can affect wheel fit, braking clearance, and driving safety.
Common considerations when replacing wheels
Beyond bolt pattern, pay attention to wheel offset, width, diameter, and center bore. Even with a correct 5x100 pattern, incorrect offset or a mismatch in bore size can cause clearance or hub-fit issues. If in doubt, consult a professional or stick with wheels listed as compatible for your exact Impreza year and market.
Summary: The Subaru Impreza’s standard bolt pattern is 5x100, a 5-lug arrangement on a 100 mm bolt circle. This has been consistent through most generations, but always verify against your specific model year, market, and VIN-based specs to ensure proper fit and safety.
