Audi RS4 B9 with 20×10-inch Korbach Forged PS3 Wheel

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. This one stands out. The combination of the Grey exterior with the Korbach Forged PS3 creates a look that balances aggression with elegance.

Let us walk you through exactly what makes this setup work.

Full Specs Breakdown: Korbach Forged PS3 on Audi RS4 B9

Here is exactly what this owner is running. We break down every detail so you can replicate this build or use it as a starting point for your own.

The wheels measure 20×10 inches. That is a serious size choice for the Audi RS4 platform. It fills the wheel wells and gives the car a planted, wide-body look without actually needing wide-body fenders.

The offset sits at ET26. This number controls how far the wheel face sits from the hub mounting surface. On this Audi RS4 B9, an offset of ET26 positions the wheel perfectly within the fender line.

The owner went with a Gloss Black finish. We think this is one of the best finish choices for a Grey car. It creates contrast without clashing.

Tire choice matters just as much as the wheel itself. This build runs 275/30R20 tires. The right tire size ensures proper sidewall profile, prevents rubbing, and keeps the ride comfortable for daily driving.

Fitment Breakdown: Korbach Forged PS3 on the Audi RS4 B9

Okay, so we're drooling over this Audi RS4 B9. It's rocking 20x10 Korbach Forged PS3 wheels. These are meaty! The ET26 offset is key here. It pushes the wheel out just enough for that aggressive stance.

A 20x10 wheel is wide for the RS4. But the ET26 offset is perfect to avoid poking too much. It also maximizes inner clearance. We've seen guys struggle with anything more aggressive without serious fender work.

Caliper clearance on these Audis can be tight. The PS3's spoke design curves just right to clear those massive brakes. We always double-check this. No one wants to grind down their calipers.

That 275/30R20 tire size is spot-on. It gives a nice, square sidewall. We think it fills the fender wells nicely without looking stretched. A little stretch on a B9 RS4 just looks wrong.

The hub bore is crucial. Make sure the wheels are either the correct bore, or you use hub-centric rings. Vibration is the enemy. We hate chasing vibrations after a wheel install.

If this RS4 had aftermarket suspension, it would change the game. Lowering springs or coilovers affect how the wheel sits. We would probably consider adjustable control arms. This fixes camber issues when you go low.

Rubbing can be an issue with this aggressive setup. Especially at full lock or over big bumps. The front fender liners are usually the first to go. Heat gun and a little persuasion works wonders.

What We Recommend for Audi RS4 B9 Owners

For an RS4 B9, we think 19 to 20-inch wheels are ideal. They look great and maintain decent ride quality. 20s fill the arches better. But 19s give you more tire sidewall for comfort.

We've found the offset sweet spot is between ET25 and ET30. This gives you that flush look without major headaches. Aggressive offsets look cool. But the headaches are not worth it.

Square setups are the easiest to live with. You can rotate tires to extend their life. Staggered setups look cool. But they require more planning and can affect handling.

Avoid excessive tire stretch on this platform. It looks out of place on a performance sedan. Plus, you lose valuable grip. Grip is king on the RS4.

Rolling your fenders might be necessary for super aggressive setups. But we recommend starting conservative. See if you can dial it in with camber adjustments first.

A common mistake we see is choosing the wrong tire size. Use an online calculator to verify fitment. Don't just guess. We learned this the hard way!

Before You Buy: Fitment Checklist for Audi RS4 Owners

Understanding wheel sizing: diameter, width, offset and backspacing all affect fitment on your Audi RS4.

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.

What offset should I run? We recommend checking builds similar to this one in our Audi RS4 B9 gallery. Real-world fitment data beats guesswork every time.
