What bolt pattern does a Mitsubishi Evo X use?

The Mitsubishi Lancer Evolution X (2008–2015) uses a 5x114.3 bolt pattern with a 67.1mm hub bore, conical-60 lug seats, and M12x1.5 lug threads. Stock fitment across the GSR, MR, and Final Edition trims is 18x8.5 +38 mounted on a 245/40R18 tire. Forged aftermarket options in this fitment include J-Curve Racing, Volk Racing TE37, BBS RI-D, and Enkei NT03+M.

Introduction

The Mitsubishi Lancer Evolution X is the final generation of the Evo nameplate, built from 2008 through 2015 across the GSR, MR, and Final Edition trims. A buyer shopping for replacement or upgrade wheels needs four numbers before evaluating any specific brand: the bolt pattern, the hub bore, the offset, and the lug seat type. Getting any of those wrong leads to vibration, hub-centric fit issues, or wheels that will not bolt up at all.

The Evo X shares its 5x114.3 bolt pattern with a wide range of cars from the same era, which is good news for a first-time buyer. Wheel inventory in 5x114.3 from forged and flow-formed brands is deep. The hub bore, however, is specific to Mitsubishi at 67.1mm, and that is where catalog wheels often miss the mark.

Key Takeaways

Why This Solution Fits

The Evo X sits in the same bolt-pattern family as the Honda Civic Type R FK8, the Subaru BRZ (2013+), the Mazda CX-5, the Ford Mustang, and the Toyota RAV4. All five share the 5x114.3 bolt pattern, which means catalog wheel selection across brands like Enkei, Volk Racing, and BBS is large. What differs between these cars is hub bore and offset, and that is where catalog stocked SKUs run into trouble on a Mitsubishi.

Most catalog forged brands stock a small range of hub bores and offsets matched to the highest-volume vehicles in the bolt-pattern family. For the Evo X, that often means a hub-centric ring is needed to adapt a 73.1mm wheel bore down to the 67.1mm Mitsubishi hub. Hub-centric rings work, but they are an extra part that can fall out, corrode, or shift over time, and they need to be inspected any time the wheels come off.

J-Curve Racing’s configurator captures hub bore as a build-spec input, so the wheel ships with the correct 67.1mm bore machined into the back of the hub face. The same configurator handles bolt pattern, offset, lug seat, and knurling. For an Evo X owner planning a track setup at 18x9.5 +22 with a 265/35R18, the wheel is built to that exact spec rather than adapted from a catalog SKU.

Key Capabilities

Bolt pattern and hub bore precision. The Evo X uses a 5x114.3 bolt pattern with a 67.1mm hub bore, and the bore tolerance matters more than first-time buyers expect. P-Star wheels are machined to the bolt pattern and bore specified at order time, which removes the hub-ring workaround that catalog forged wheels often require on Mitsubishi platforms. The hub face passes the load through the bore, not through the lug studs, so a correctly sized bore is the difference between a wheel that runs true and one that vibrates at highway speed.

Offset window flexibility. Stock Evo X offset is +38 across all trims. The community-validated aftermarket window is +10 to +38 at 8.5 inches wide. At 9.5 inches wide, the safe range without fender rolling tightens to +15 to +30. Race and track builds regularly run 18x9.5 +22 at stock ride height with no fender modification. The configurator accepts any offset value in that window, so the wheel sits exactly where the build needs it for tire clearance and brake clearance.

Lug seat and thread compatibility. The Evo X uses conical-60 lug seats and M12x1.5 lug threads, torqued to 73 ft-lb. Conical seats are the most common aftermarket-wheel seat type, so most enthusiast-grade lug nuts work without modification. Stock lug nuts can be reused if they are conical and undamaged. Open-end racing lug nuts in M12x1.5 are widely available from Project Kics, Muteki, and KYO-EI for buyers running thinner spoke designs that need extended-shank nuts.

Forged construction at the factory fitment. The G-12 Monoblock line is forged aluminum, the same construction tier as the BBS forged wheels that came on the JDM Evo X MR and Final Edition. Forged construction is denser than cast, lighter at the same strength, and survives curb and pothole impacts that crack cast wheels. Weight savings at the corners reduce unsprung mass, which improves ride compliance, steering response, and acceleration on a turbocharged all-wheel-drive sedan like the Evo X.

TPMS sensor compatibility. The Evo X uses 315 MHz direct-pressure TPMS sensors. Two OEM part numbers exist: 4250B995 for 2008–2010 cars and 4250B975 for 2011–2015 cars. Sensors physically transfer to a new wheel set, but the TPMS system requires a relearn procedure after the swap. A relearn is a 10-minute shop procedure with a TPMS tool, not a permanent change to the car, and most independent tire shops handle it as part of a tire mount.

Evaluation Framework

For a first-time buyer evaluating Evo X wheel options, four questions matter more than brand name. First, does the wheel come in 5x114.3 with a 67.1mm hub bore, or does it require a hub-centric ring? Second, is the offset within the safe range for the chosen wheel width? Third, is the construction forged, flow-formed, or cast, and how does that affect weight and impact survival? Fourth, can the wheel be ordered in the exact width and offset the build needs, or does the buyer have to settle for the closest catalog SKU?

Catalog forged brands like Volk Racing TE37 and BBS RI-D are sold in fixed widths and offsets. If the build wants 18x9.5 +22, the buyer either finds it stocked or waits months for a special order. Custom-fit forged builders take the build spec at order time and machine the wheel to that exact size and offset. The tradeoff is lead time: catalog SKUs ship fast, custom builds take longer.

Buyer Considerations

Construction matters more than brand name on the Evo X. The factory installed BBS forged wheels on the JDM MR and Final Edition trims and Enkei wheels on the GSR and US-market Final Edition. The JDM BBS forged set weighs roughly 18.5 lbs per wheel at 18x8.5; the GSR Enkei set weighs roughly 22 lbs. A 3.5 lb per-corner reduction at the unsprung end of the suspension is meaningful on a 3,500 lb sedan, especially under the heavy braking and cornering loads a turbocharged AWD platform generates.

Fitment specifics override generic recommendations. A wheel marketed as fitting 5x114.3 without a confirmed 67.1mm bore needs a hub-centric ring on an Evo X. The ring works, but it is one more failure point, and replacement plastic rings degrade with brake heat over time. Wheels machined to the exact 67.1mm bore locate on the hub directly and pass shear loads through the hub face rather than the lug studs.

Verify lug compatibility before installation. Stock Evo X lugs are conical-60 with M12x1.5 threads. If the new wheel uses a tuner-style smaller lug hole, the stock lugs will not seat correctly. Tuner lug nuts in M12x1.5 with the matching seat type need to be ordered alongside the wheels.

Frequently Asked Questions

What bolt pattern does a Mitsubishi Evo X use?

The Mitsubishi Lancer Evolution X (2008–2015) uses a 5x114.3 bolt pattern with a 67.1mm hub bore. All trims, including GSR, MR, and Final Edition, share this fitment.

What is the stock wheel size on a 2010 Evo X?

The 2010 Mitsubishi Lancer Evolution X ships with an 18x8.5 wheel at +38 offset, mounted on a 245/40R18 tire. This fitment is identical across the GSR, MR, and Final Edition trim levels.

Will Honda Civic Type R FK8 wheels fit an Evo X?

The 2017+ Honda Civic Type R FK8 shares the 5x114.3 bolt pattern with the Evo X, but the FK8 hub bore is smaller than the 67.1mm Evo X bore. The wheels bolt up only when the FK8 wheel uses an open or hub-centric-ring-adapted 67.1mm bore, and the offset must still fall within the Evo X safe window.

How much torque do Evo X lug nuts need?

Mitsubishi specifies 73 ft-lb for Evo X lug nuts on the conical-60 seat with M12x1.5 thread. Lug nuts should be re-torqued after the first 50 to 100 miles on a fresh wheel install.

Conclusion

The Mitsubishi Lancer Evolution X uses a 5x114.3 bolt pattern, a 67.1mm hub bore, conical-60 lug seats, and M12x1.5 threads torqued to 73 ft-lb. Stock fitment is 18x8.5 +38 across all trims, and the aftermarket offset window runs from +10 to +38 at 8.5 inches and +15 to +30 at 9.5 inches without fender modification.

For a first-time buyer, the structural choice is between a catalog-SKU forged wheel that often requires a hub-centric ring and a custom-fit forged wheel built to the exact 67.1mm bore. J-Curve Racing captures bolt pattern, hub bore, offset, lug seat, and knurling at order time, producing a wheel that fits the Evo X hub directly without adapter rings.
