Audi RS3 Wheel Fitment Guide (2017-2022) | 5x112mm
The 8V RS3 is one of those cars that looks fast standing still, but the factory 19x8 +49 setup leaves real meat on the table. That +49 offset tucks the wheel face well inside the fender, and on a car with the RS3's fender flares and aggressive haunches, there's plenty of room to fill. Drop the offset, widen the barrel, and this thing transforms.
The 5x112mm bolt pattern and 57.1mm center bore give you access to a massive catalog of wheels, so you're not fighting for options. The five-cylinder soundtrack deserves a stance that matches, whether that means a clean square setup for track duty or a proper staggered fitment that plants the rear and dials in the front.
We've pulled together four fitment examples below — a mix of square and staggered builds we selected to show what actually works on the RS3 platform. Each one takes a different approach to width, offset, and tire choice, so you can see how the specs translate to the road before committing to your own build.

Want new wheels for your Audi RS3?
The RS3's stock 19x8 +49 setup is conservative by design — that +49 offset tucks the wheel face well inside the fender, leaving room on the table. Running a 5x112mm bolt pattern, you've got access to one of the deepest aftermarket catalogs out there, so finding something to fill those arches is the easy part.
We stock Flow Technik for guys who want a clean, cast-flow-formed setup that shaves weight over the OEM cast wheels without the forged price tag. If you're chasing a full custom build, BC Forged opens up made-to-order widths, offsets, and finishes — pick your face, pick your specs, done.
Sizing-wise, 19" keeps you in the sweet spot for tire selection and ride quality, 18" is the move if you're going track or want more sidewall, and 20" tightens up the look if you want max diameter. Square or staggered, the 5x112 catalog has you covered.

Brake clearance
The 2017–2022 RS3 (8V/8V.5) doesn't mess around up front — it runs 8-piston Brembo fixed calipers on 370mm front rotors from the factory, with a carbon-ceramic option available. Those are big calipers on a compact platform, so spoke geometry matters more here than on most cars.
Minimum diameter: 18-inch will clear the factory 8-piston steel and carbon-ceramic brakes, with 19-inch giving more margin. Below 18" is a non-starter.
Spacers: Depending on your wheel's ET and width, a thin front spacer may be needed to clear the caliper body — plan for it if you're running a barrel-hugging concave face. The RS3 uses a 57.1mm hub, so run the correct hub rings on any 5x112 fitment.
18-Inch Square Setup
Going square on the RS3 keeps things balanced and rotation-friendly, and this BC Forged setup runs 18x9 at all four corners — a clean, no-compromise footprint that works for both track duty and street looks.

| Notes | Stock | |
This RS3 keeps it clean and purposeful with a square setup, running the BC Forged RZ39 Brushed dark black 18x9 +45 at all four corners. The brushed dark finish gives it a stealthy, factory-plus attitude that suits the RS3's understated aggression.
Wrapped in 245/40/18 on stock suspension, the sidewall gives it a balanced, planted look without going overboard. The matched setup keeps the stance even and honest — no drama, just a tidy, confident face on a proper daily-driver hot hatch.
19-Inch Setups
Nineteens are the sweet spot for the RS3, and these two builds show the range — a set of Flow Technik and a pair of BC Forged, running widths from 19x8.5 up to 19x9.5. One's square, one's staggered, so scroll through and see which layout speaks to you.

| Notes | Stock | |
Clean and purposeful on this RS3 — the Flow Technik FT108 19x8.5 +30 up front sits a touch more aggressive than the Flow Technik FT108 19x8.5 +40 in the rear. Same width, staggered offsets — a subtle setup that tucks the rear in slightly while the front pushes out. It's the kind of detail you only catch walking around the car.
Wrapped in 245/35/19 front and 245/35/19 rear on stock suspension, it keeps things factory-height and functional. Not loud — just right.

| Notes | Stock | |
This RS3 keeps it clean and purposeful with a proper square setup — the BC Forged RZ21 19x9.5 +45 sits at all four corners for a balanced, motorsport-minded look. The +45 offset tucks the face in just enough to let the multi-spoke design do the talking.
Wrapped in 255/30/19 rubber on stock suspension, this thing looks factory-fast without trying too hard. Consistency across every corner is exactly what makes a square RS3 setup like this so satisfying to walk up to.
20-Inch Square Setup
Square 20x9 all around keeps the RS3 balanced and rotation-friendly, and this BC Forged setup shows how clean that formula looks on the platform.

| Notes | Stock | |
The RS3 already looks mean from the factory, and dropping a set of BC Forged HC010 20x9 +45 at all four corners cleans up the whole look. The square setup keeps it balanced and purposeful — no gimmicks, just the same wheel doing its job front and rear.
The 245/30/20 wraps that 20x9 tight, giving the face plenty of room to breathe over stock suspension. Understated and consistent — exactly how a fast Audi should sit.
Final Thoughts on Audi RS3 Fitment
Final Thoughts
The RS3 gives you a lot of room to work with on the 5x112mm platform, and these four builds prove it. Across the 18, 19, and 20" setups featured here, offsets landed between +30 and +45 — a window that keeps the wheel face sitting clean under those aggressive Audi arches without overthinking it. Some of these builds run square, others go staggered, so let the look you're chasing dictate which direction you lean.
If you want the simplest starting point, 20x9 was the most common size across these setups, and it's an easy spec to build around whether you're going square for balance or staggered for a bit more attitude out back. The 18s and 19s in this guide are worth a look too — smaller diameters open up more sidewall and a more forgiving ride, which the RS3 chassis rewards on rougher roads. Pick the diameter that matches how you actually drive the car.
Every wheel in this guide is something we stock, so once you've settled on your diameter and offset, ThreePiece.us can get you sorted with the brands featured here — mounted, balanced, and ready to bolt on. Come find your setup and let's build it right.
