Subaru BRZ Wheel Bolt Pattern: A Complete Fitment Guide
Direct Answer and Scope
The Subaru BRZ uses a 5x100 millimeter bolt pattern for both the first generation (model years 2013 through 2021) and the second generation (model year 2022 and later). The pattern is expressed as five bolt holes arranged on a circle with a diameter of 100 millimeters. This specification applies to all factory wheel options sold in North America, including the base 17-inch alloy wheels and the optional 18-inch wheels. No factory variant or trim level changes this measurement.
Supporting Wheel Fitment Specifications
Wheel bolt pattern alone does not guarantee a safe fit. Three additional measurements matter for the BRZ. The center bore is 56.1 millimeters. The factory wheel stud thread pitch is 12x1.25 millimeters. The recommended lug nut torque specification is 89 foot-pounds, or 120 newton-meters. Aftermarket wheels with a larger center bore require hub-centric rings to seat correctly on the hub.
Generation-Specific Offset Notes
Factory wheel offset differs slightly between generations. First-generation BRZ wheels carry an offset of +48 millimeters for the 17-inch wheels. Second-generation models use a factory offset of +48 millimeters for the base 17-inch wheel and +45 millimeters for the available 18-inch wheel. Offset measures the distance between the wheel mounting surface and the wheel centerline. A lower positive number pushes the wheel outward toward the fender.
Practical Fitment Guidance
When selecting aftermarket wheels, verify the 5x100 pattern, the 56.1 millimeter center bore, and an offset reasonably close to factory range. Many aftermarket wheels use a larger bore to fit multiple vehicles; in that case, hub-centric rings are required to prevent vibration. Reuse or replace lug nuts with the correct 12x1.25 thread pitch. Torque the lug nuts to 89 foot-pounds in a star pattern and recheck after approximately 50 miles of driving.
Common Misconceptions
The BRZ shares its platform and bolt pattern with the Toyota GR86 and the earlier Scion FR-S, but not with most Subaru models. Several Subaru vehicles, including the WRX and many older Legacy models, also use a 5x100 pattern, but newer WRX generations and other Subaru crossovers may use 5x114.3. A wheel from a 5x114.3 Subaru will not fit the BRZ without an adapter, which is not recommended for street use. Always confirm the pattern stamped or listed on the specific wheel rather than assuming brand compatibility.
