About This Audi RS5 B9 Build
We love featuring real builds from real owners. This White Audi RS5 B9 sits on a set of 20-inch BC Forged EH173 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 White exterior with the BC Forged EH173 creates a look that balances aggression with elegance.
Fitment Breakdown: BC Forged EH173 on the Audi RS5 B9
I walked around this B9 RS5 for twenty minutes yesterday, and the stance is perfect. We are looking at 20-inch BC Forged EH173 wheels sitting flush against those wide fenders. The fitment is aggressive, but it stays within the lines of the bodywork.
The EH173 design features a unique multi-spoke geometry that clears the massive factory brake calipers easily. We often see owners struggle with barrel clearance on these cars, but BC Forged nailed the offset here. There is no rubbing, even under hard cornering.
We see a 275/30/20 tire setup mounted on these wheels. That width provides plenty of grip without ballooning over the rim edge. It looks tight and intentional from every single angle.
The KW coilovers pull the chassis down just enough to eliminate the ugly factory gap. That drop changes the entire geometry of the wheel well. The tire now sits perfectly parallel to the fender liner.
These wheels feature a custom hub bore designed specifically for the Audi platform. We hate using hub-centric rings, and this setup avoids them entirely. The direct fit ensures zero vibration at highway speeds.
The barrel depth gives the car a deep, concave look that draws your eye in. BC Forged pushed the spokes right to the edge of the rim. It makes the 20-inch wheels look even larger than they are.
Pay close attention to the rear clearance on these B9s. You have to watch the inner liner when you go this wide. This specific build stays safe by keeping the offset dialed in perfectly.
What We Recommend for Audi RS5 B9 Owners
If you want this look, stick to the 20-inch diameter. Going up to 21 inches ruins the ride quality on these cars. We find 20s are the absolute sweet spot for aesthetics and performance.
Offset is your best friend when ordering custom wheels. We recommend staying between ET20 and ET25 for a flush fitment on the B9. Anything more aggressive will force you to roll your fenders, which is a nightmare.
Always run a square setup on these AWD platforms. Staggered wheels might look cool, but they confuse the Quattro system. Stick to the same width at all four corners to save your center differential.
Don't skimp on your tire selection for a setup like this. A 275-width tire works best for the EH173 design. It provides a clean, square profile that keeps the sidewalls looking sharp.
Avoid cheap spacers at all costs. We see people try to "fix" fitment with 10mm spacers, and it just leads to wobbles. Order your BC Forged wheels with the correct offset from day one.
Style and Build Analysis
The White paint on this RS5 pops against the dark finish of the EH173 wheels. It is a high-contrast look that demands attention without being loud. The monochromatic vibe keeps the car looking classy and fast.
The EH173 spokes are thin but incredibly strong. They open up the wheel well and let you see the rotors and calipers behind them. It turns the brakes into a design feature rather than a hidden part.
I love how the stance highlights the RS5 body lines. The wide fenders look ten times better when the wheels actually fill the space. It looks like a proper DTM car ready for the track.
We see a lot of B9 builds, but many fail the proportion test. This one gets the balance right between the heavy body and the mechanical wheels. It feels substantial and planted on the asphalt.
This car commands the road with a presence that factory wheels simply cannot match. It looks fast even when parked. This is exactly how an RS5 should look when you leave the dealer lot.
Why We Love This Build
This White RS5 catches the sunlight and turns into a masterpiece. The BC Forged EH173 wheels tuck perfectly into the arches, creating a silhouette that flows like water. Every time I see it, I have to stop and take another look.
The aggressive drop from the KW coilovers gives the car a predatory stance. It looks like it wants to hunt down every apex on the map. This build proves that less is more when you pick the right parts.
I want to drive this car every single day. It reminds me why we love the Audi platform so much. Do your car a favor and get this setup.

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-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-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
