About This Ford Focus RS 2017 Build
We love featuring real builds from real owners. This Black Ford Focus RS 2017 sits on a set of 18×8.5 / 18×8.5-inch Konig Dekagram wheels, and the result speaks for itself.
The owner chose Konig for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Ford Focus RS builds come through WheelFront every month, but this one stands out. The combination of the Black exterior with the Konig Dekagram creates a look that balances aggression with elegance.
Fitment Breakdown: Konig Dekagram on the Ford Focus RS 2017
I walked around this black Focus RS for twenty minutes straight. The Konig Dekagrams in an 18x8.5 setup change the entire character of the car. We love this square configuration because it keeps the handling neutral and predictable.
The 43mm offset lands right in the sweet spot for the Focus RS platform. It pushes the wheels out just enough to clear the massive Brembo calipers without needing spacers. I checked the clearance myself, and it is absolutely perfect.
We see a lot of guys struggle with hub bore issues, but these wheels fit the Ford hub perfectly. You do not need any sketchy hub rings to keep the ride smooth. It makes for a rock-solid mounting surface that handles aggressive cornering with ease.
The 18-inch diameter allows for more sidewall meat compared to the factory 19s. That extra rubber soaks up road imperfections and keeps your rims safe from potholes. I noticed how the tire profile fills the wheel well even on the stock suspension.
The Dekagram's flow-formed construction keeps the unsprung weight low. Every pound you shave off the wheels makes the steering feel sharper and more direct. We felt the difference instantly during our spirited drive through the canyons.
You might worry about rubbing, but this setup stays well within the fender liners. Even at full lock, the tires clear the frame rails without any drama. It is a true bolt-on fitment that requires zero modifications to the bodywork.
The spoke design angles outward just enough to provide a deep, aggressive look. It creates a visual illusion that makes the wheel appear wider than it actually is. We think this is the best aesthetic choice for a daily-driven RS.
What We Recommend for Ford Focus RS 2017 Owners
If you own an RS, stick to the 18-inch diameter for your track or street wheels. Moving to 19s usually hurts your performance and increases the chance of wheel damage. We always recommend the 18x8.5 square setup for the best balance.
Offsets between 40mm and 45mm represent the golden rule for this car. Anything lower than 40mm will poke too far and spray rocks all over your paint. We have tested plenty of setups, and 43mm hits the mark every single time.
Forget about staggered setups on this all-wheel-drive platform. You need identical tire diameters at all four corners to keep the differential happy. Mixing wheel widths will just lead to expensive drivetrain headaches later on.
Be smart with your tire selection to complement the new width. A 245/40/18 tire gives you a nice, square sidewall that protects the rim. Avoid excessive stretch unless you enjoy ruining your wheel lips on the first curb you meet.
Do not feel pressured to roll your fenders on this specific setup. You have plenty of room to play with once you install a set of lowering springs. Keep your factory fenders intact and keep your resale value high.
Style and Build Analysis
This black-on-black aesthetic looks absolutely sinister in person. The matte finish of the Dekagrams provides a subtle contrast against the deep gloss of the Ford paint. It gives the car a stealthy, tactical look that demands respect.
The multi-spoke geometry of the Konig design draws your eye straight to the brake package. Because the RS has such distinct calipers, you want a wheel that frames them properly. These spokes leave enough negative space to showcase the hardware behind them.
Proportions matter more than anything else when you build a car. By shrinking the wheel diameter and keeping the offset flush, this RS looks planted and ready for a rally stage. It sits with an authority that the stock wheels simply cannot match.
We have featured many RS builds, but this one captures the essence of the car best. It avoids the "try-hard" look of cheap, oversized wheels and focuses on pure function. It is a masterclass in tasteful, calculated modification.
The light catches the edges of the spokes when the car moves, adding a nice bit of movement. It feels like a cohesive package rather than a collection of random parts. This is how you build a Focus RS for the long haul.
Why We Love This Build
This black Focus RS is a total street weapon that looks fast even when it is parked. The Konig Dekagrams fill the arches with a sense of purpose that transforms the car's entire silhouette. When the sun hits the black paint, the wheels disappear into the shadows while the tires look perfectly tucked. It is the kind of build that makes us turn our heads every time we walk away from it.
We love that this owner chose function over flash. This car isn't just a garage queen; it is a machine built to carve up back roads and survive the daily grind. It is simple, effective, and damn near perfect. You need this setup.

Before You Buy: Fitment Checklist
We talk to Ford Focus RS owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×8.5 / 18×8.5-inch wheels fit my Ford Focus RS? 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 Ford Focus RS owners run 18×8.5 / 18×8.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
