About This Audi RS4 B9 Build
We love featuring real builds from real owners. This Grey Audi RS4 B9 sits on a set of 20×10-inch Korbach Forged PS3 wheels, and the result speaks for itself.
The owner chose Korbach Forged for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Audi RS4 builds come through WheelFront every month, but this one stands out. The combination of the Grey exterior with the Korbach Forged PS3 creates a look that balances aggression with elegance.
Fitment Breakdown: Korbach Forged PS3 on the Audi RS4 B9
I walked around this B9 RS4 for twenty minutes just to admire the fitment. The 20x10 Korbach Forged PS3 setup fills those massive factory arches perfectly. We see a lot of builds, but this one hits the mark on every metric.
The ET26 offset sits right at the edge of the fender without crossing into trashy territory. It pushes the wheel face out just enough to kill that sunken stock look. You get a broad, aggressive stance that still keeps the tires tucked safely.
Caliper clearance remains a massive hurdle on the B9 platform. These PS3s offer plenty of room for those oversized RS iron brakes. I didn't see a single sign of contact or heavy spacer usage.
The hub bore fits the Audi factory specs like a glove. We hate using hub-centric rings because they just cause vibration headaches later on. These wheels bolt straight up without any drama.
The spoke design allows for a decent amount of barrel depth. It gives the wheel a three-dimensional pop that flat-faced designs totally lack. You catch the light hitting those spokes at every angle.
The 275/30R20 tires provide a nice, square shoulder profile. They fill out the wheel well without requiring a hacksaw to the fender liners. You maintain the car's handling dynamics while gaining a wider contact patch.
This car runs a mild drop, which tightens up the fender gap significantly. If you go much lower, you might catch the plastic liner on big bumps. Stick to this height if you actually want to drive the car hard.
What We Recommend for Audi RS4 B9 Owners
Do not go wider than a 10-inch wheel unless you plan on doing serious wide-body work. Anything past that will just turn your fenders into scrap metal during a hard turn. Keep your sanity and stick to the 20x10 spec.
For offsets, keep your numbers between ET25 and ET30. Anything lower than 25 will poke way too far and look like a cheap drift project. Anything higher than 30 will force you to run spacers, which we strongly advise against.
Run a square setup every single time on this platform. The Quattro system hates staggered rolling diameters and will chew through your center differential. Stick to the same wheel and tire size at all four corners.
Tire choice matters just as much as the wheel itself. I recommend a performance summer tire like the Michelin Pilot Sport 4S for this setup. A 275 width offers the best balance of grip and aesthetics for this chassis.
Don't bother with fender rolling unless you are obsessed with "slammed" life. The RS4 fenders are already flared enough to accommodate a smart wheel choice. Keep the factory lines intact and save your money for better mods.
Style and Build Analysis
The Gloss Black finish against that Grey paint is a classic, lethal combination. It creates a high-contrast look that makes the car look darker and meaner. You can't go wrong with this color palette.
The PS3 design feels modern without being over-styled. It complements the sharp, aggressive body lines of the B9 generation perfectly. These wheels don't try too hard, which is why they look so right.
Proportion is everything when you modify a car like this. The 20-inch diameter works because it matches the scale of the large RS4 body panels. Anything smaller would look lost in those gaping wheel arches.
I’ve seen plenty of RS4s on aftermarket wheels that just look wrong. Many owners choose designs that are too busy or finish choices that clash with the grey. This build succeeds because it stays focused on clean, purposeful lines.
The road presence of this car is undeniable. It looks like it belongs on a mountain pass or parked in front of a high-end garage. It’s a masterclass in how to upgrade a car while keeping its soul.
Why We Love This Build
This RS4 stops us in our tracks because it looks fast even when it sits perfectly still. The way the Gloss Black wheels catch the light under the grey arches creates a menacing, cohesive shadow. It is exactly how an RS car should look when the owner puts in the real work.
We see thousands of cars, but this specific fitment feels deliberate and refined. You can tell the owner studied the offsets before committing to the order. It is a build that inspires confidence and makes you want to hit the key and find the nearest highway.
This is the kind of setup that makes you look back every time you walk away. Buy the right wheels, nail the stance, and just drive the damn thing.

Before You Buy: Fitment Checklist
We talk to Audi RS4 owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20×10-inch wheels fit my Audi RS4? Yes, but fitment depends on width, offset, and tire size working together. A wrong offset means rubbing. A wrong tire size means poor handling. Always verify all three.
Do I need to modify my fenders? That depends on your offset and suspension. A conservative offset with stock ride height usually fits without modification. Go aggressive and you may need to roll or pull your fenders.
Can I daily-drive this setup? Absolutely. Thousands of Audi RS4 owners run 20×10-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
