About This Acura RSX Type-S 2006 Build
We love featuring real builds from real owners. This Acura RSX Type-S 2006 sits on a set of 18×9 / 18×9-inch Cosmis-Racing XT-206R 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-206R creates a look that balances aggression with elegance.
Fitment Breakdown: Cosmis-Racing XT-206R on the Acura RSX Type-S 2006
I walked around this RSX for ten minutes just staring at the fitment. The 18x9 setup with a +33 offset hits that aggressive sweet spot perfectly. It fills the arches without looking like a monster truck.
Running a square 18x9 setup on an RSX requires some serious attention to detail. That +33 offset pushes the wheel face right out to the fender line. It creates a flush look that most owners only dream about.
The XT-206R design clears those factory Type-S calipers with room to spare. I hate when big brakes hide behind flat spokes, but these have a nice concave profile. The spokes curve inward just enough to add depth.
You need to consider your hub bore when mounting these wheels. The RSX uses a 64.1mm hub, so grab some high-quality hub-centric rings. This prevents those nasty vibrations at highway speeds.
Since this car sits on coilovers, the geometry changes everything. We dropped the ride height until the tire sat just inside the fender lip. It looks mean, but you have to watch the inner clearance.
Watch out for rubbing on the front liners during full lock turns. You might need to pull the fender tabs or adjust your camber settings slightly. A little negative camber goes a long way here.
The barrel lip depth on the XT-206R gives this car a purposeful track-ready aesthetic. It feels solid and planted on the asphalt. This is how a tuned RSX should sit.
What We Recommend for Acura RSX Type-S 2006 Owners
If you want a daily-driven RSX, stick to an 18x8.5 or 18x9 setup. Anything wider requires aggressive body work that ruins the clean lines. You want to drive the car, not just look at it.
The +30 to +35 offset range remains the gold standard for this platform. It keeps the scrub radius manageable and preserves the steering feel. Don't go lower than +30 unless you enjoy eating fenders.
I always suggest a square setup for these front-wheel-drive chassis. It allows for tire rotations that save you money in the long run. Plus, it makes the car handle predictably in corners.
Don't skip the fender roll if you plan on going low. Even a minor roll gives you the extra clearance needed for speed bumps. It takes ten minutes but saves your paint from cracking.
Avoid excessive tire stretch if you value your wheels. A nice meaty sidewall protects the rim edge from potholes and curbs. It also puts more rubber on the road where it counts.
Style and Build Analysis
The Black finish on these Cosmis wheels creates a brutal, monochromatic vibe. It contrasts sharply against the body lines of the RSX. This car looks like it wants to hunt down everything else on the road.
The six-spoke design of the XT-206R is timeless and aggressive. It complements the angular headlights and sharp hood lines of the DC5 generation. The wheels look like they belong there from the factory.
Proportions define a build, and this one nails it. The wheels fill the wheel wells without looking cartoonish or over-the-top. Everything flows from the front bumper to the rear wing.
I compare this build to some of the heavy hitters we feature on the site. It lacks the gaudy add-ons that ruin so many other tuner cars. It relies on clean fitment and quality parts to do the talking.
The stance gives the car a sense of gravity and purpose. It sits low, wide, and ready for whatever the street throws at it. You can see the engineering thought behind every choice here.
Why We Love This Build
This RSX stops me in my tracks because it feels complete. The black wheels swallow the light and give the car a menacing, low-slung profile that demands respect. When the sun hits the paint, the whole car glows, making those dark wheels pop even harder.
It captures the golden era of Japanese tuning while staying relevant today. We see thousands of cars, but this specific setup is just honest and clean. It makes me want to pull my own RSX out of the garage and start ordering parts immediately.
This is the definitive look for the DC5 platform. Stop overthinking your build and just go with this proven recipe.

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 18×9 / 18×9-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 18×9 / 18×9-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
