2022+ GR86 & BRZ Wheel Fitment: Offset and Width Guide

Your 2022+ Toyota GR86 or Subaru BRZ doesn't sit too high. It sits too narrow. The ZN8/ZD8 left the factory on 17x7.5 +48 (or 18x7.5 +48 on Premium trims) wrapped in a 215-section tire, and that combination parks the wheel face roughly an inch inboard of where the fender arch lives. This GR86 wheel fitment guide covers the offset and width that actually fills those arches — 5x100, 56.1 bore, square, no guessing.

Your GR86 isn't high, it's narrow

Every meet has one: a clean ZN8 sitting an inch and a half down on coilovers that still reads awkward. The owner circles the car looking for the problem. The problem is that dropping a narrow wheel just moves a narrow wheel closer to the ground. Width is what reads as low. Half the GR86s people call "perfect stance" are running less drop than yours and more wheel.

That's not a styling opinion, it's geometry. A +48 offset on a 7.5" rim puts the outer barrel deep under the arch, and no amount of ride height changes the relationship between the tire's outer shoulder and the fender lip. If you want to see what the corrected version looks like across a bunch of chassis, our vehicle gallery is full of cars that solved width before they solved height.

Factory specs: 5x100, 56.1 bore, +48

Here's the full factory recipe for the ZN8/ZD8:

• Bolt pattern: 5x100
• Hub bore: 56.1mm
• Base wheel: 17x7.5 +48 on 215/45R17
• Premium wheel: 18x7.5 +48 on 215/40R18
• Studs: M12x1.25, factory torque in the 85–90 lb-ft range

That +48 isn't laziness. It's a global-market number built to clear a MacPherson strut, survive a curb strike in a market that doesn't care about your fitment, and pass homologation in every country the car ships to. It's also the single spec standing between you and a car that looks like it costs twice as much. If offset math still feels abstract, our Evo VIII/IX offset guide walks through the same inboard/outboard tradeoff on another strut-front chassis.

One more note: 5x100 is a shrinking pool. It's shared with the older FR-S/BRZ, some VWs, and older Subarus — which means you're shopping a narrower catalog than the 5x114.3 crowd. Filter properly and browse 18-inch 5x100 wheels before you fall in love with a face that was never cast in your pattern.

The street spec: 18x9.5 +38 on 255/35

The answer for a street car is 18x9.5 +38, square, all four corners, on 255/35R18. Run the math against stock and you're moving the outer edge roughly 35mm outboard versus a 7.5 +48 — 25.4mm of that from the extra inch per side of width, 10mm from the offset drop. That's the entire gap between "buried" and "filled."

Square, not staggered. The ZN8 makes its money on rotatable tires and a Torsen out back — staggering it is cosplaying a chassis it isn't, and you lose the ability to rotate a set of expensive 200TW rubber. Speaking of which, read how to pick a 200TW tire before you commit to a compound, and check 255/35R18 tires for sizing availability.

For wheels, the Work Emotion series is the obvious lane here because it's actually cast in usable 5x100 widths and offsets. The Work Emotion T7R at $432 is the safe, always-correct answer; the Work Emotion CR Kiwami at $270 is the budget entry that still looks like it belongs. If you're skipping the ladder entirely, the Work Emotion CR 3P at $895.50 gets you into real three-piece construction with a barrel you can re-spec later — see our Work Meister S1 3P review for why that matters long-term.

The track spec: 17x9 +35 on 255/40

If the car sees HPDE or autocross, stay on 17s. 17x9 +35 on 255/40R17 gives you a taller sidewall for curb abuse, cheaper consumables, and a wider selection of the 200TW tires that actually matter at this power level. The FA24's 228 hp doesn't need a 19-inch anything — it needs contact patch and a spare set you're not afraid to flat-spot.

Browse 17x9 wheels in 5x100 and pair them with 255/40R17 tires. If you're building a dedicated second set on a budget, our Vors TR4 review covers the cheap-track-wheel end honestly, and track vs street tires explains why you shouldn't try to make one set do both jobs.

What it actually costs you

Nothing is free. Here's the honest bill:

• Rear fenders want a roll. On 18x9.5 +38 with a mild drop, most owners never touch the fronts, but the rears will find the lip under load if you're aggressive.
• Hubcentric rings aren't optional. The hub is 56.1mm and most aftermarket wheels are bored larger. Running hub-centric-by-lug-nut and calling it fine is how you end up chasing a vibration you'll blame on the tires. Grab proper hubcentric rings and the correct M12x1.25 lug nuts at the same time as the wheels.
• Go lower on offset and the front gets tight. Dropping from +48 to +38 on a 9.5 also moves the inner barrel about 15mm toward the strut. Push past that and you're into rubbing at full lock.
• Keep the drop reasonable. 1.25–1.5 inches. This chassis lives on suspension travel; slamming it destroys the exact thing you bought the car for. The BC Racing DS-Series at $1,395 is the sane street entry point. First-gen ZC6 owners have more options — the Function & Form Type 2 at $980 or the Fortune Auto 500 Series at $1,918.36 if you want rebuildable damping. Full suspension catalog here.
• Rubber costs more. A 255 square is more tire money than factory 215s — but you rotate all four and only stock one size.

While you're in there, finish it properly. Center caps, a 90-degree valve stem at $3.80 for deep-lip barrels, and if you went three-piece, keep spare M7 assembly bolts on the shelf.

Pick one and commit

Street car: 18x9.5 +38 square on 255/35R18. Track car: 17x9 +35 on 255/40R17. Both are correct answers. The half-measure — an 8.5 at +44 because it "definitely won't rub" — is the only wrong one, because it costs the same money and changes nothing about how the car reads. While you're planning the build, our BRZ/86 cat-back guide covers the other half of the personality transplant.

Start with the wheel catalog, filter to 5x100, and don't let a +48 face talk you into a fourth set of wheels next spring.

So which did you land on — 18x9.5 +38 street or 17x9 +35 track — and did you actually need the fender roll or did everyone just tell you that you would?
