Subaru WRX Wheel Bolt Pattern by Year
Direct Answer for the 2013 WRX
The 2013 Subaru WRX uses a 5x100 millimeter wheel bolt pattern. This applies to the factory wheel fitment for that model year, regardless of whether the car is the sedan or hatchback body style. The notation means the wheel has five lug holes arranged on a circle with a diameter of 100 millimeters.
Why the Bolt Pattern Changes by Model Year
The WRX does not use one bolt pattern across all production years. The critical dividing line is the generation change for the 2015 model year. Before 2015, the WRX shared its 5x100 pattern with many smaller Subaru models. From 2015 onward, the WRX moved to a larger 5x114.3 millimeter pattern. This change affects wheel interchangeability between older and newer cars.
Bolt Pattern by Model Year Group
Model Year Range | Bolt Pattern | Center Bore; 2002-2014 | 5x100 mm | 56.1 mm; 2015-2021 | 5x114.3 mm | 56.1 mm; 2022-present | 5x114.3 mm | 56.1 mm
The center bore of 56.1 millimeters is consistent across these WRX generations. While the bolt pattern changed, the hub diameter remained the same, which matters when selecting hub-centric rings for aftermarket wheels.
2015 WRX Wheel Bolt Pattern
The 2015 WRX uses a 5x114.3 millimeter bolt pattern. This is the first model year of the VA-generation WRX, and the change from 5x100 is not backward compatible. Wheels from a 2013 WRX will not bolt onto a 2015 WRX without an adapter, which is generally not recommended for a performance vehicle.
2017 WRX Wheel Bolt Pattern
The 2017 WRX continues with the 5x114.3 millimeter pattern. No mid-cycle refresh for the VA chassis altered the wheel bolt spacing. Factory wheels from a 2015, 2016, or 2018 WRX will fit a 2017 model directly, assuming the same wheel diameter and offset are acceptable for brake clearance.
2018 WRX Wheel Bolt Pattern
The 2018 WRX also uses a 5x114.3 millimeter bolt pattern. For owners of a 2018 WRX, this means a wider range of factory Subaru wheels from other 5x114.3 models, such as the STI and larger Legacy and Outback models, may fit the hub pattern, though offset and caliper clearance must still be checked.
Additional Wheel Measurements That Matter
The bolt pattern is only one part of wheel fitment. The WRX also requires attention to thread pitch, offset, and wheel width. The lug nut thread pitch for the 2015 and later WRX is 12x1.25 millimeters. Factory offsets generally range from +53 to +55 millimeters, but aftermarket wheels often use lower offsets. Changing the offset can affect steering feel, bearing load, and fender clearance.
What to Verify Before Buying Wheels
Check the wheel bolt pattern against the specific model year, not just the model name; a 2014 WRX wheel will not fit a 2015 WRX. Confirm the center bore matches or use hub-centric rings for aftermarket wheels. Verify the offset keeps the tire clear of the strut and fender under suspension travel. For 2015 and later cars, confirm the lug nut seat type matches the wheel; factory wheels use a 60-degree conical seat.
Summary of Fitment
A 2013 WRX requires a 5x100 wheel. A 2015, 2017, or 2018 WRX requires a 5x114.3 wheel. Using the wrong bolt pattern wheel is not possible without modification, so the model year must be confirmed before purchase. This is the primary supported distinction in WRX wheel fitment across the years covered.
