What size wheels fit on a brz?
This article explains which wheel sizes fit a Subaru BRZ (and the related Toyota 86 family), covering bolt pattern, hub bore, and practical size ranges for street and enthusiast setups.
The BRZ uses a 5-lug, 100 mm bolt pattern with a hub bore around 56.1 mm. You can safely run wheels in the 17x7 to 18x8 range, with typical offsets around ET45–ET50. For street use, common tire sizes are 215/45R17 or 225/40R18, depending on wheel width. Always verify clearance with brake calipers, fenders, and suspension before buying.
Bolt pattern, hub bore and fitment basics
Wheel fitment on the BRZ hinges on three constants that determine compatibility: bolt pattern, center bore, and offset. The standard BRZ setup uses a 5-lug pattern on a 100 mm circle, with most aftermarket BRZ-compatible wheels offering a hub bore near 56.1 mm. Matching the offset is key to preserving steering feel and avoiding contact with brakes, fenders, and suspension components.
Key numbers to check
When evaluating wheels, look for: 5x100 bolt pattern, a hub bore close to 56.1 mm (or the use of hub rings if needed), and an offset (ET) in the mid-40s to mid-50s for typical street builds. Exact values depend on brake packages and suspension geometry, so confirm clearance on your specific car before purchasing.
Stock sizes and year-to-year variation
The BRZ has seen small variations in factory wheels across model years and trims, but several patterns recur. Use these baselines when comparing wheels to your car.
- 17-inch wheels are common on many BRZ trims, often paired with lower-profile tires for balanced handling.
- 18-inch wheels are more common on higher trims or sport-oriented packages, frequently paired with wider tires for grip.
- Wheel widths typically range from about 7 to 8 inches for street wheels, with offsets roughly in the 40s to 50s depending on brake package and fender clearance.
These baselines help you avoid misfit issues. If your BRZ has upgraded brakes or a modified suspension, clearance can change, so always verify with the specific wheel you intend to mount.
Common aftermarket options and how they fit
For enthusiasts, the most popular upgrade paths involve moving to 18-inch wheels with wider tires or maintaining a lighter 17-inch setup for a blend of handling and acceleration. The following guidelines summarize sizes that fit most BRZs with stock suspension and brakes, along with typical offset ranges.
- 17x7.0 to 17x7.5 wheels with ET45–ET50 are a safe starting point for many BRZs using 215–225 mm tires.
- 18x7.5 to 18x8.0 wheels with ET45–ET50 can fit on many BRZs, often paired with 235 mm tires for improved grip.
- Wider rear wheels up to about 9.0 inches can fit on some builds with fender adjustments, typically around ET40–ET48, but rubbing is possible without modification.
Always verify fitment on your exact car, especially if you have upgraded brakes or a lowered suspension. When in doubt, consult a wheel/tire professional to confirm clearances.
How to verify fit and avoid rubbing
To ensure a wheel size truly fits, check clearance at full steering lock, full suspension travel, and during dynamic movement. Confirm caliper and rotor clearance, along with any potential contact with fender edges or liners. If unsure, test with a temporary setup or work with a professional to confirm the final fit.
Using a reputable fitment guide or seeking professional advice helps prevent costly errors and ensures the wheels you choose won’t rub or compromise safety.
Summary
Choosing wheels for a BRZ centers on a 5x100 bolt pattern and a hub bore near 56.1 mm, with typical street fitments ranging from 17x7 to 18x8 and offsets around ET45–ET50. Common tire pairings include 215/45R17 or 225/40R18, depending on width. Always verify exact clearance for your year, trim, brakes, and suspension, and consult a wheel specialist if you’re planning aggressive setups or major brake changes. A careful fitment check helps maintain safety, handling, and the BRZ’s driving feel.
What size are stock BRZ rims?
5x100 ET35
The Subaru BRZ bolt pattern is 5x100. 18" Wheels is the most popular sizing for all generations of Subaru BRZ. Paired with a 35mm offset (ET35), you can achieve a more flushed look. If you'd like to stay closer to the oem fitment, we recommend using a 45mm offset (ET45).
What is the best wheel width for the BRZ?
If you are looking to go with a square fitment we would recommend an 8.5″ wide wheel at an ET40 offset OR if you are looking to run a staggered setup you can run the same size in the front of the car but go a bit wider for the rear at a 9″ wide wheel at an ET40 offset as well.
Will 18x9.5 fit BRZ?
Best Fitment Specs for a Flush Toyota GR86, Subaru BRZ or Scion FR-S. Moving on to the flush setups, an 18x9. 5 wheel setup with a +38mm offset can work wonders for giving you that flush look you crave, but if you want to go a little bit lower, it's a good idea to snag yourself a set of coilovers.
What size tires are on a Subaru BRZ?
The standard BRZ tire sizes are 215/45R17 (for the Premium model) and 215/40R18 (for the Limited and tS models). Common aftermarket upgrades include larger or wider tires, such as 225/40R18 or 245/40R17 and 245/40R18, depending on wheel size and suspension modifications.
Factory sizes
- 215/45R17: Often found on the Premium trim.
