About This Ford Focus RS 2017 Build
We love featuring real builds from real owners. This Ford Focus RS 2017 sits on a set of 18×9.5 / 18×9.5-inch BC-Forged RS45 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 Ford Focus RS builds come through WheelFront every month, but this one stands out. The combination of the exterior with the BC-Forged RS45 creates a look that balances aggression with elegance.
Fitment Breakdown: BC-Forged RS45 on the Ford Focus RS 2017
I walked around this Focus RS for a solid hour at the show last weekend. The 18x9.5 square setup on this car hits that perfect sweet spot for the chassis. We usually see 19s on these, but dropping to 18s gives the car so much more character.
The +40 offset is exactly what this platform needs to push the wheels flush with the fenders. You get that aggressive track stance without needing a ridiculous amount of poke. It looks purposeful and planted.
Those BC-Forged RS45 wheels clear the massive Brembo calipers with ease. We often worry about barrel clearance on the RS, but these spokes arc out just enough. You get plenty of room to breathe.
Since the owner threw on lowering springs, the fender gap is basically gone. The wheel arch hugs the tire perfectly now. It creates a seamless look from the rim to the bodywork.
I checked the inner clearance near the strut towers while we had it on the lift. You have enough room, but you have to watch your tire profile. A chunky sidewall might kiss the liner if you hit a big dip.
The hub bore fits the RS hub perfectly, so there is no vibration at highway speeds. We always suggest hub-centric rings if you go aftermarket, but these specific BC-Forged units are machined to spec. It makes the install foolproof.
The flat profile of the RS45 spokes gives the car a timeless rally aesthetic. It looks like it belongs on a stage or a circuit. I love how the wheel design flows with the sharp body lines of the Ford.
What We Recommend for Ford Focus RS 2017 Owners
If you own an RS, stick to a square setup like this one. Staggered setups destroy the AWD system on these cars, so keep the widths identical front to back. We want handling, not just show.
Aim for an offset between +38 and +42. Anything lower than +35 will stick out too far and throw road debris all over your quarter panels. You want the tire tucked just inside the arch.
Do not go wider than 9.5 inches unless you plan on doing some serious fender work. The RS has limited space inside the rear arches. You will rub on the plastic liners if you get too greedy.
We always recommend running a 255/35 or 265/35 tire on this setup. A 255 gives you a clean look with minimal stretch. It keeps the steering sharp and responsive, which is why we bought the car in the first place.
Avoid cheap spacers at all costs if you can help it. Buying a custom-offset wheel from a brand like BC-Forged saves you from the headache of wobbles and alignment issues. Do it right the first time.
Style and Build Analysis
The Gunmetal finish on these wheels is subtle but menacing. It creates a sharp contrast against the body paint, especially under the bright show lights. It looks moody and aggressive without trying too hard.
The RS45 is a classic multi-spoke design. It reminds me of the old-school rally wheels but with a modern, forged twist. It feels right at home on a hot hatch like the Focus.
When the car is sitting still, the proportions look spot on. The wheels fill the arches perfectly, making the car look much lower than it actually is. It has a heavy, grounded road presence.
I have seen plenty of RS builds with flashy, multi-piece wheels that clutter the look. This choice is different because it keeps the car feeling like a performance machine. It stays true to the Ford DNA.
The way the light hits the concave spokes at an angle is just killer. It adds depth to the side profile that the factory wheels simply cannot touch. This is a masterclass in tasteful modification.
Why We Love This Build
Seeing this Focus RS in person made me realize that wheels truly make or break the build. The Gunmetal finish catches the sunset, highlighting the intricate spoke pattern of the BC-Forged wheels. It fills the arches so tightly that the car looks like a predator waiting to pounce. We love this car because it respects the heritage of the RS while elevating its stance to a pro-level aesthetic.
This car stops us in our tracks because it balances form and function perfectly. You can drive this hard on a mountain road or park it at a meet, and it looks world-class in both settings. The lowered ride height and the aggressive offset work in harmony to transform the factory look into something special. It is exactly how a Focus RS should look.
Go get yourself a set of these and watch your car change completely.

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 18×9.5 / 18×9.5-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 18×9.5 / 18×9.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
