About This Audi RS5 B9 Build
We love featuring real builds from real owners. This Blue Audi RS5 B9 sits on a set of 20×10.5-inch BC Forged RZ05 wheels, and the result speaks for itself.
The owner chose BC 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 RS5 builds come through WheelFront every month, but this one stands out. The combination of the Blue exterior with the BC Forged RZ05 creates a look that balances aggression with elegance.
Fitment Breakdown: BC Forged RZ05 on the Audi RS5 B9
I walked around this B9 RS5 for twenty minutes yesterday, and the stance is perfect. We are looking at 20x10.5 BC Forged RZ05s on all four corners. That massive width fills the wheel wells like the factory never intended.
The B9 chassis is notoriously picky about offsets. These wheels hit that sweet spot where the face sits flush with the fender line without poking like a bro-truck. It creates a mean, grounded profile that screams performance.
Caliper clearance is always the elephant in the room with these big Audi brakes. BC Forged engineered the barrel design here to clear those massive front stoppers easily. We saw plenty of breathing room, so you will not worry about interference during hard driving.
The hub bore on these is machined specifically for the Audi platform. No cheap hub-centric rings required here. That direct fitment ensures the car tracks straight and true at high speeds on the highway.
Because the owner went with a 10.5-inch width, the barrel lip depth is aggressive. It gives the RZ05 a deep, concave look that draws the eye toward the center cap. The design flows beautifully with the sharp body lines of the RS5.
The owner lowered the car on a high-end coilover kit, which changes the game entirely. That drop eliminates the wheel gap and tucks the tires perfectly. It looks like it belongs on a track, not just the local cars and coffee lot.
Watch out for rubbing if you go this wide, though. You might need a slight fender liner modification if you plan to slam the car lower than this. Stay smart with your ride height to keep your paint pristine.
What We Recommend for Audi RS5 B9 Owners
If you want this look, start with the right width. A 10-inch wheel is the safe bet, but the 10.5 setup we featured today is the "gold standard" for a reason. Just commit to the aggressive offset and make it work.
Avoid the temptation of running cheap spacers to fix poor wheel choices. Do it right the first time with custom forged wheels like these BCs. You gain unsprung weight savings and better structural integrity for your daily commute.
We see a lot of guys mess up the tire choice. This owner went with 285s up front and 305s in the rear for a staggered contact patch. That setup puts the power down and keeps the quattro system happy.
Avoid excessive tire stretch if you actually drive your car hard. We prefer a square-shouldered tire that protects the rim edge from nasty potholes. It keeps your investment safe while providing the grip you paid for.
Never ignore the suspension setup when choosing wheels. If you stay on factory air or stock springs, stick to a more conservative offset. Throwing wide wheels on a stock suspension setup usually creates a weird, lifted look that nobody wants.
Style and Build Analysis
The Gloss Black finish on these RZ05s is the perfect choice for this blue paint. It creates a high-contrast look that feels modern and aggressive. Black wheels usually hide detail, but the spoke geometry here cuts through the darkness.
The visual impact of this combo is immediate. You notice the deep blue hue first, then your eyes snap directly to those dark, metallic wheels. It looks expensive, focused, and deliberate.
The RZ05 design is timeless, featuring a multi-spoke pattern that mimics classic racing wheels. It avoids the clutter of too many spokes while maintaining a sophisticated, high-end feel. It fits the B9’s angular aesthetic perfectly.
Compared to other builds, this one keeps the "less is more" philosophy alive. There are no tacky body kits or oversized wings here. The wheels and the stance do all the heavy lifting for the car’s personality.
The proportionality is spot on. We see too many cars with wheels that look like an afterthought, but these belong here. The car looks like a factory-backed special edition rather than a collection of aftermarket parts.
Why We Love This Build
This RS5 hits differently when the sun starts to set. The blue paint deepens, and the gloss black finish on those RZ05 wheels starts to look like liquid ink. You can see the reflection of the road in the barrels as it rolls into the parking lot. Every time I walk past it, I stop to look at the way the tires hug the fender edges. It is a masterclass in restraint and performance-focused styling.
The stance is low, the color palette is sharp, and the engineering is top-tier. This is exactly how you build a modern performance icon. It makes me want to start a B9 project of my own immediately. Perfection is hard to achieve, but this build nails it.

Before You Buy: Fitment Checklist
We talk to Audi RS5 owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20×10.5-inch wheels fit my Audi RS5? 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 RS5 owners run 20×10.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
