About This Ford Focus ST 2018 Build
We love featuring real builds from real owners. This Ford Focus ST 2018 sits on a set of 18×10.5 / 18×10.5-inch Cosmis Racing MRII wheels, and the result speaks for itself.
The owner chose Cosmis Racing 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 ST builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Cosmis Racing MRII creates a look that balances aggression with elegance.
Fitment Breakdown: Cosmis Racing MRII on the Ford Focus ST 2018
I walked around this Focus ST at the show and the fitment honestly stopped me in my tracks. Running 18x10.5 wheels on a hot hatch like this is a massive commitment. These Cosmis Racing MRIIs push the limits of what this chassis can handle.
The +20 offset is aggressive, to put it mildly. You are pushing the wheels way past the factory fenders here. That width demands a serious widebody kit or some very creative metal work.
Clearing those stock front calipers requires a wheel with a specific spoke profile. The MRII design gives us just enough room to breathe without needing massive spacers. We measured the gap, and it sits right where we want it.
The hub bore fits tight against the Focus ST hubs, which is exactly what we look for. You never want vibrations shaking your steering wheel at highway speeds. Everything here feels solid and built to last.
That barrel lip depth really defines the look of the MRII. It gives the car a deep, concave face that makes the 18-inch diameter feel huge. It fills the arches perfectly when the air suspension hits the floor.
We need to talk about the rubbing, though. With this much width and a +20 offset, your tires will touch the liners during tight turns. You have to roll those fenders or pull them unless you want to eat your sidewalls.
Running air suspension makes this setup usable. When you air out, the tires tuck neatly behind the fender lips. It is a work of art when the car settles into its final stance.
What We Recommend for Ford Focus ST 2018 Owners
If you want to run a wide setup, start with your suspension choice first. Air ride gives you the flexibility to drive daily and park hard. Static guys will struggle to keep this fitment drivable without constant headaches.
Stay within the 18x8.5 to 18x9.5 range if you want to keep your sanity. Pushing past 10 inches wide on a Focus ST requires a dedicated widebody build. Don't try to force this look on a stock body unless you plan to cut metal.
Aim for an offset between +35 and +42 for a flush look without the drama. We see guys try to run +20 offsets on stock fenders and it never ends well. You end up with shredded tires and cracked paint.
Choose your tires carefully to match the wheel width. A slight stretch helps clear the fenders, but don't overdo it. You still need enough meat to actually put that turbo power to the pavement.
We always suggest testing your clearance at full lock. Find an empty lot and crank the wheel to both sides. If you hear plastic grinding, adjust your height or pull your fenders before you leave the driveway.
Avoid cheap spacers if you can help it. Buying a wheel with the correct offset from the start saves you time and stress. Do it once, do it right, and enjoy the ride.
Style and Build Analysis
The white finish on these wheels pops against the factory paint. It creates a high-contrast look that feels sporty and clean. We see too many black wheels, so this bright choice really stands out.
Those six thick spokes give the wheel a rally-inspired vibe. It fits the Focus ST personality perfectly since this car feels like a rally weapon on the street. The MRII design looks tough and functional all at once.
The stance is everything on this build. By sitting low on air, the car looks like it belongs on a magazine cover. The proportions feel balanced despite the aggressive width of the wheels.
We compare this to other builds we feature and this one wins on pure confidence. Most owners play it safe with conservative offsets and dark colors. This owner chose to make a loud statement with white paint and massive lips.
The car looks planted even when it is sitting still. It has that wide, aggressive road presence that every enthusiast craves. When the light hits the white spokes, the whole design comes to life.
Why We Love This Build
This Focus ST makes my heart beat faster every time I see it parked in the lot. The bright white Cosmis wheels capture the light and demand total attention. Watching the car air out until the lips tuck under the fenders is pure mechanical bliss. It is the perfect blend of aggressive stance and rally heritage that makes this platform so iconic. You can tell the owner put hours of thought into every single millimeter of clearance. This build proves that if you have the vision, you can transform a daily driver into a total showstopper. Get out there and build something that makes you look back every time you walk away.

Before You Buy: Fitment Checklist
We talk to Ford Focus ST owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×10.5 / 18×10.5-inch wheels fit my Ford Focus ST? 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 ST owners run 18×10.5 / 18×10.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
