Will STi wheels fit Crosstrek?
Many STI wheels can fit a Subaru Crosstrek because both models commonly use a 5x100 bolt pattern and similar center bore, but fitment ultimately depends on offset, width, and brake clearance for your exact year and wheel design. If the dimensions don’t align, you may face rubbing or braking issues, and spacers or different wheels may be required.
Compatibility snapshot
The Crosstrek and many STI wheel designs share the essential specs, but there are caveats. The key is to verify three main dimensions: bolt pattern, center bore, and offset/width. Other factors include brake caliper clearance and fender/travel clearance, as well as load rating and tire compatibility.
- Bolt pattern matches: 5x100 on most Crosstrek generations and STI wheels; a 5x114.3 pattern would require adapters (not generally recommended).
- Center bore: 56.1 mm is common on Subaru vehicles; if the wheel bore is larger, hub-centric rings can center the wheel; if smaller, the wheel won’t mount without modification.
- Lug seat type and hardware: Subaru typically uses lug nuts with a conical/tapered seat; ensure the wheel’s seat type and thread size match your lug hardware.
- Wheel width and diameter: STI wheels come in a range (often 17–18 inches in various widths); wider wheels or nonstock widths can rub inner fenders or suspension if offsets aren’t matched.
- Brake clearance: Larger or uniquely designed STI wheels may contact brake calipers or larger rotors; verify caliper clearance for your build.
- Tire size and overall diameter: Maintain a compatible overall diameter to avoid speedometer inaccuracy and gearing changes; verify tire compatibility for the chosen wheel.
Conclusion: If the wheel’s bolt pattern, center bore, offset, width, and brake clearance line up with your Crosstrek, STI wheels can fit. If any dimension is off, you risk rubbing, braking interference, or other issues.
Technical compatibility details
Bolt pattern and center bore
Most Subaru Crosstrek models run a 5x100 bolt pattern with a center bore around 56.1 mm. STI wheels used on WRX/STI platforms have historically matched this pattern and bore, but there are exceptions by generation or aftermarket designs. If the wheel bore is larger, hub-centric rings can help with centering; if smaller, the wheel won’t mount properly.
- If the wheel is 5x100 with a 56.1 mm bore, it will typically center and mount correctly on a Crosstrek.
- Wheels with a different bolt pattern (e.g., 5x114.3) require adapters, which can compromise safety and handling and are generally not recommended.
Conclusion: Start by confirming the exact STI wheel’s 5x100 pattern and 56.1 mm bore for a straightforward fit, and consider rings only if the bore is larger than 56.1 mm.
Offset, width, and clearance
Offset (ET) and width determine how far the wheel sits from the hub and how much clearance exists to the fenders, calipers, and suspension. The Crosstrek’s suspension geometry and fender design tolerate some variance, but wheels that are significantly wider or have a different offset can rub under compression or during full steering lock. Aim to keep offset within a range that preserves close-to-stock clearance, and verify brake caliper clearance for the specific STI wheel design.
- Wider STI wheels with low offsets can push the wheel outward, risking rubbing on fender lips or caliper clearance.
- A much higher offset can push the wheel inward, affecting steering response and clearance.
Conclusion: Matching offset and width to the Crosstrek’s stock values minimizes rubbing and brake interference. If in doubt, perform a careful test fit with the tire mounted and consult a professional if needed.
Practical steps to confirm fitment
Before purchasing or attempting to mount STI wheels on a Crosstrek, follow these steps to confirm compatibility and avoid surprises on the road or at the shop.
- Collect exact wheel specs: bolt pattern, center bore, offset, width, diameter, and lug seat type, then compare against your Crosstrek’s specs.
- Check brake clearance and caliper size for the specific STI wheel design you’re considering.
- Assess fender and suspension clearance; consider a test fit with the intended tire size to gauge rubbing under compression.
- Consult a reputable tire/wheel shop or Subaru technician to verify feasibility and to discuss spacers or other accommodations if needed.
Conclusion: Do not rely on appearance alone. Accurate measurements and professional confirmation are essential when mixing STI wheels with a Crosstrek.
Safety, warranty, and alternatives
Mixing wheels across model lines can affect warranty coverage, ride quality, and safety. If the wheels aren’t a proper fit, you risk contact with brakes, suspension, or fenders, which could lead to accelerated wear or damage. If you’re uncertain, consider Crosstrek-approved aftermarket wheels or OEM alternatives from Subaru that publish explicit fitment for your year and trim.
Summary
In short, STI wheels can fit a Crosstrek in many cases thanks to common bolt pattern and bore, but exact fit depends on offset, width, and brake clearance. Always verify the specific wheel model’s 5x100 pattern, 56.1 mm bore, lug seating, and the wheel’s width/offset against your Crosstrek’s specs. When in doubt, seek professional guidance, and use hub-centric rings or spacers only as a last resort and with caution.
What is the bolt pattern on a Subaru Crosstrek?
The Subaru Crosstrek bolt pattern is 5x100 for models from 2013-2023, but it changed to 5x114.3 (also known as 5x4.5) for the 2024 and newer models. Therefore, compatibility depends on the vehicle's model year.
By model year
- 2013-2023: 5x100
- 2024 and newer: 5x114.3 (5x4.5)
What this means for you
- If you have a 2013-2023 Crosstrek: You need wheels with a 5x100 bolt pattern.
- If you have a 2024 or newer Crosstrek: You need wheels with a 5x114.3 (5x4.5) bolt pattern.
- If you have older wheels: Wheels from a 2013-2023 Crosstrek will not fit a 2024 or newer model, and vice versa.
Is Crosstrek just a lifted Impreza?
Like the Outback Sport, the Crosstrek is a lifted Impreza hatchback with minor differences, though with a more substantial lift than the Outback Sport. Initially, the vehicle was marketed as the XV globally, and as the XV Crosstrek in the United States and Canada.
What Subaru has a 5x114.3 bolt pattern?
If you're looking for the latest, most advanced wheels with the 5x114. 3 bolt pattern, 2015 WRX wheels, 2015 STI wheels, 2018 STI wheels, 2020 STI wheels, 2021 STI wheels, and 2022 WRX wheels are all great choices.
What is the bolt pattern on a STI wheel?
The STI bolt pattern is 5x114.3 for most models from 2005 onward, but the 2004 STI model uses a 5x100 bolt pattern. This difference in bolt pattern is a key distinction for parts compatibility, so it's essential to verify the year of the STI before purchasing wheels or other related parts.
By year and model
- 2004 STI: 5x100
- 2005-2007 STI: 5x114.3
- 2008-2023 WRX STI: 5x114.3
Why it matters
- Wheel and brake fitment: The bolt pattern (also called PCD, or Pitch Circle Diameter) must match exactly for a wheel to bolt on properly.
- Performance and design: The switch to a 5x114.3 pattern starting in the 2005 STI allowed for more robust wheel options and improved brake setups.
