Best Subaru WRX & STI Wheels: Sizes, Fitment & Picks

The right set of Subaru WRX and STI wheels does more than change how your car looks — it drops rotating and unsprung mass, sharpens turn-in, and frees you to run a wider, stickier tire. But before you fall for a finish, you have to get the fitment right, and the single most important number is your bolt pattern. The 2002–2014 WRX uses a 5x100 bolt pattern, while every STI (2004–2021) and every 2015-and-up WRX uses 5x114.3. Get that wrong and the wheel simply will not bolt on. Below, our team at NLP Performance in Tampa, FL breaks down the best proven WRX and STI wheels we stock — from the legendary Enkei RPF1 to forged SSR Type-C — with the exact sizes, offsets, and bore specs you need to order with confidence.

Why the Right Wheels Matter on a WRX or STI

Wheels are the highest-value handling upgrade per dollar on a turbocharged Subaru because they attack unsprung and rotational mass at the same time. A lighter wheel is easier for the suspension to control over broken pavement and easier for the drivetrain to spin up and slow down, which is why autocrossers and time-attack drivers obsess over wheel weight. Shaving even 4–6 lb per corner off a heavy OEM or replica wheel improves acceleration, braking response, and steering feel — with zero effect on your warranty or emissions.

The WRX and STI also respond well to a wider footprint. The factory STI ran a 245-width tire on an 8.5-inch wheel; stepping to a proper 8.5- to 9.5-inch-wide aftermarket wheel lets you fit 255- to 265-width rubber for measurably more mechanical grip. The wheels in this guide range from a track-focused 17x8 all the way to an aggressive 18x9.5, so you can match the wheel to your goal — daily street, canyon, autocross, or time attack.

WRX vs STI Wheel Fitment: Bolt Pattern, Bore and Offset

The 2002–2014 Subaru WRX uses a 5x100 bolt pattern; every STI (2004–2021) and every 2015-and-newer WRX uses 5x114.3. This is the number one fitment mistake Subaru owners make, because the two platforms look nearly identical. Both share a 56.1mm hub bore, so most aftermarket wheels ship with a larger bore (73mm or 75mm on the wheels below) and rely on hub-centric rings to center the wheel on the 56.1mm hub. Always run the correct hub rings.

What offset should I run on a WRX or STI?

For a rub-free daily setup, a 17x8 wheel around +45 offset (like the RPF1) tucks neatly under a stock or lightly lowered fender. Moving to an 18x8.5 at +40 to +48 is the sweet spot for a 255-width square track setup. The most aggressive wheel here — the SSR Type-C at 18x9.5 +22 — sits flush to the fender and typically wants a lowered car, a 265-width tire, and possibly light fender work. When in doubt, more positive offset (higher number) pulls the wheel inward and is the safer starting point.

Best Subaru WRX and STI Wheels We Stock

We grouped our top picks by bolt pattern so you can shop the ones that actually fit your car. The first three fit 5x114.3 (STI and 2015-plus WRX); the last two are 5x100 for the 2002–2014 WRX.

1. Enkei RPF1 — Best Overall (5x114.3)

The RPF1 is the wheel that defined affordable performance for a generation of Subarus. Enkei builds it with their MAT (Most Advanced Technology) flow-forming process, which spins and compresses the barrel to produce a wheel that weighs roughly 16 lb in 17x8 — lighter than most forged wheels twice its price. In gold on a World Rally Blue STI it is an icon; on track it simply works. At under $300 per wheel it is the easiest recommendation in this guide.

2. SSR Type-C Forged — Premium Pick (5x114.3)

When you want the last word in wheels, SSR's Type-C is a forged, classic mesh design made in Japan — the same lineage that has been on show cars and time-attack Subarus for decades. Forging aligns the aluminum grain for maximum strength at minimum weight, so an 18x9.5 forged wheel can weigh less than an 18x8.5 cast one. The aggressive +22 offset and 9.5-inch width put a 265-width tire flush to the fender for a proper wide-body STI stance. At around $1,000 per wheel it is a premium buy, but it is the range-topper here for a reason.

3. SSR GTV01 — Best Value Track Look (5x114.3)

The GTV01 gives you the SSR name and a clean split 5-spoke track look at a cast-wheel price. In 18x8.5 +40 it is the ideal square setup for a 255-width tire on an STI, tucking under a stock fender with a mild drop. It is heavier than the forged Type-C, but for a street car that sees the occasional track day it is a smart, durable buy under $500 per wheel.

4. fifteen52 Turbomac — Best Rally Style (5x100)

If your WRX is a 2002–2014 5x100 car, the fifteen52 Turbomac nails the rally-heritage look that suits a Subaru perfectly. The classic dished 5-spoke in Rally White pays homage to Group B and gravel-stage Imprezas, and the 17x7.5 +30 sizing is a friendly, rub-free fit that clears the factory brakes and takes a wide-enough 235- to 245-width tire. At just under $300 per wheel it is our favorite street-and-style pick for the older WRX.

5. SSR GTX01 — Best Flow-Formed 5x100 (2002–2005 WRX)

For a 2002–2005 WRX owner who wants a lighter, larger-diameter wheel without going forged, the flow-formed SSR GTX01 is the pick. The 10-spoke 18x8.5 +44 design steps you up to an 18-inch fitment with a modern face while staying rub-free on 5x100 hubs, and the flow-forming keeps weight in check versus a fully cast 18. It is a clean, durable daily-and-canyon wheel just over $450 per wheel.

WRX and STI Wheel Comparison

Cast vs Flow-Formed vs Forged: Which Wheel Should You Buy?

Forged wheels are the strongest and lightest, flow-formed wheels are the best value for weight, and cast wheels are the most affordable. A cast wheel (like the SSR GTV01 or fifteen52 Turbomac) is poured into a mold — durable and inexpensive, but heavier. Flow-forming (Enkei RPF1, NVR5, SSR GTX01) starts as a cast center and then spins the barrel under heat and pressure to align the metal grain, cutting weight while adding strength. Forging (SSR Type-C) presses a solid billet under enormous force for the best possible strength-to-weight, at the highest price.

Whichever construction you choose, pair the wheel with the correct 56.1mm hub-centric rings and torque your lug nuts to Subaru's spec (around 89 lb-ft).
