About This Acura RSX Type-S 2004 Build
We love featuring real builds from real owners. This Acura RSX Type-S 2004 sits on a set of 18×10 / 18×10-inch Cosmis Racing XT-005R 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 Acura RSX Type-S builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Cosmis Racing XT-005R creates a look that balances aggression with elegance.

Fitment Breakdown: Cosmis Racing XT-005R on the Acura RSX Type-S 2004
I walked around this RSX for ten minutes at the last show, and the fitment is absolute madness. Running an 18x10 setup on all four corners of a DC5 chassis takes some serious guts. Those Cosmis XT-005R wheels push the limits of what this platform can swallow.
The +20 offset forces the wheels way out toward the edge of the fender. You get a massive amount of poke if you do not dial in your alignment settings perfectly. I noticed the owner runs a healthy amount of negative camber to tuck those shoulders under the arches.
Clearance at the front caliper is never an issue with the XT-005R design. The spoke profile kicks out aggressively to clear big brake kits without needing spacers. You get a deep, menacing barrel lip that defines the look of the car.
The hub bore sits right where it needs to be for a clean, vibration-free mount. Still, you have to watch for rubbing on the fender liner during hard cornering. The 10-inch width means the tire sidewall gets very close to the inner shock body.
These coilovers are the only reason this setup works at all. You need a stiff spring rate to prevent the tire from eating the metal of the fender under compression. Without that tight suspension setup, this car would shred its tires in a single mile.

Pay close attention to the rear trailing arm clearance when you run this width. We checked the gap, and it is paper-thin. You have to be precise with your coilover dampening settings to keep the rear end from dancing into the rubber.
This isn't a bolt-on-and-go kind of fitment. It demands fender rolling and a serious commitment to alignment specs. But man, when you see that 10-inch width filling the wheel wells, you know it was worth every drop of sweat.
What We Recommend for Acura RSX Type-S 2004 Owners
If you want to run wide wheels like this, stop looking for an easy path. Start by rolling those fenders flat before you even think about mounting rubber. You will regret skipping this step the first time you hit a bump.
I suggest sticking to a 17-inch diameter if you want to track the car seriously. You get more tire options and less rotating mass, which helps the RSX stay nimble. If you want the show look, the 18-inch wheels like these Cosmis rollers are the way to go.
Avoid the temptation to run massive spacers unless you have a specific reason. The RSX handles best when the track width stays tight to the hub. Use your offset choice to do the heavy lifting instead of relying on cheap hardware.

Square setups are king for the DC5. Running the same width front and back lets you rotate tires and keeps the handling balance predictable. This owner nailed it by keeping the 18x10 footprint consistent across all four corners.
Watch your tire stretch carefully. Too much stretch looks like a drift car, but too little will cause massive rubbing issues on a 10-inch wide wheel. Find that middle ground where the sidewall looks clean but doesn't bulge past the rim edge.
Don't buy wheels based on a photo you saw online. Measure your current gap, calculate your desired poke, and double-check your clearance against the coilovers. If you do your homework, you can pull off this aggressive stance without hating your life on the street.
Style and Build Analysis
The choice of white on white is a bold move that pays off big time. It gives the RSX a classic rally-inspired aesthetic that screams performance. The contrast against the pavement makes the car look like it is floating.
The XT-005R design features those distinct, chunky spokes that command attention. They break up the slab-sided look of the RSX perfectly. The proportions feel heavy and deliberate, giving the car a much wider visual footprint than stock.

I love how the white finish catches the sunlight during the golden hour. It highlights the intricate geometry of the wheel spokes. Other builds often go for black or bronze, but this white setup feels fresh and clean.
This car has a presence that demands you stop and look. It sits low, wide, and aggressive without looking like a cartoon. The stance is purposeful, showing off a car that clearly sees some seat time.
We see a lot of RSX builds at WheelFront, but this one sticks in my brain. It captures the essence of the tuner culture we love. It is loud, it is bright, and it does not apologize for its existence.
Why We Love This Build
This RSX hits different because it feels finished. The white Cosmis wheels pop against the body, and the fitment is so tight it looks like it was engineered by a factory race team. Every time the light hits those white spokes, the car looks like it is ready to attack a mountain pass.
We love this build because it does not compromise. It takes an iconic platform and pushes it to the absolute edge of what is possible. It is aggressive, it is stylish, and it turns heads everywhere it rolls. This is exactly why we build cars.
Seeing this RSX in person reminds us why we fell in love with modifying cars in the first place. It is a masterclass in aggressive street fitment. Go get yourself a set and start building your own legend.

Before You Buy: Fitment Checklist

We talk to Acura RSX Type-S owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×10 / 18×10-inch wheels fit my Acura RSX Type-S? 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 Acura RSX Type-S owners run 18×10 / 18×10-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
