About This Acura TSX Base 2004 Build
We love featuring real builds from real owners. This Acura TSX Base 2004 sits on a set of 18×9.5 / 18×11-inch Cosmis-Racing XT-006R 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 TSX Base builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Cosmis-Racing XT-006R creates a look that balances aggression with elegance.
Fitment Breakdown: Cosmis-Racing XT-006R on the Acura TSX Base 2004
I stood right next to this CL9 when it rolled into the lot, and the stance is absolutely aggressive. We are talking about 18x9.5 in the front and a massive 18x11 in the rear. That 11-inch rear width completely changes the vibe of this sedan.
The offsets are key here, sitting at +10 up front and +8 in the back. These wheels push way past the factory fenders, so you definitely need some serious camber and pulled arches to make them sit right. Don't expect to bolt these on without a fight.
The XT-006R design features that signature six-spoke pattern that clears almost any brake setup. We checked the front calipers, and the barrel clearance is perfect for the stock TSX brakes. You won't struggle with hub bore issues since these fit the platform like a glove.
That deep dish on the 18x11 rear is what really catches the eye. The spokes dive hard toward the hub, creating a level of depth you rarely see on a front-wheel-drive platform. It turns the stock silhouette into something much wider and more purposeful.
Because you are running coilovers, you can dial in the height to tuck the tire right against the fender lip. I noticed just enough clearance to prevent the metal from slicing the sidewall during hard cornering. You have to be precise with your alignment specs here.
Watch out for the inner fender liner at the front. With a +10 offset, you will rub the plastic splash guard during tight parking maneuvers. We suggest pulling the liners or trimming them back to keep things clean.
This setup pushes the envelope of what people think a TSX can handle. It is not a conservative build by any stretch of the imagination. You are committing to a wide-body look without actually bolting on a wide-body kit.
What We Recommend for Acura TSX Base 2004 Owners
If you want to run these wheels, you need to be realistic about the work involved. An 18x9.5 square setup is much easier for a daily driver. Stick to offsets in the +25 to +35 range if you want to keep your factory fenders intact.
Staggered setups look mean, but they ruin your tire rotation options. We only recommend the 18x11 rear if you plan on doing a full fender flare or massive pull. Otherwise, stick to a 9.5 width all the way around.
Tire stretch is non-negotiable with these offsets. You need a slightly narrow tire profile to keep the tread away from the fender edge. A quality 225 or 235 width tire will give you the right look while helping you clear those arches.
Don't skip the fender roll. If you try to run this setup without rolling the lips flat, you will destroy your tires in the first mile. Take your time with a heat gun to prevent the paint from cracking.
Many guys make the mistake of buying wheels that are too narrow and then trying to fix it with giant spacers. That puts unnecessary stress on your wheel bearings and ruins the handling. Buy the right offset from the start and avoid the headache.
Always align the car immediately after installing the coilovers. Dial in at least two to three degrees of negative camber if you want to tuck these wheels. It keeps the car planted and keeps you out of trouble with the local police.
Style and Build Analysis
The choice of white wheels on this specific paint color is a bold move. It pops against the metal and gives the car a distinct motorsports aesthetic. I love how the bright finish highlights the intricate design of the spokes.
The XT-006R isn't a subtle wheel, and that is exactly why it works here. The sharp angles and the industrial look of the six spokes contrast perfectly with the smooth, rounded body lines of the TSX. It adds a layer of aggression that the stock sedan lacks.
When the sun hits those white barrels, the whole car looks wider than it actually is. It creates a cohesive, track-ready appearance that feels purposeful. We have seen plenty of builds, but this one captures that late-2000s tuner spirit perfectly.
Proportions are everything when you are running wheels this wide. By lowering the car on coilovers, the owner has eliminated the unsightly gap that usually ruins the look of a stock CL9. The wheels now define the profile of the entire chassis.
Compare this to a standard TSX on 17-inch wheels, and the difference is night and day. This car demands attention without being loud or obnoxious. It is a masterclass in how to change the personality of a sedan with just two key mods.
Every time we look at this build, we see something new. It proves that the TSX has timeless bones that can handle modern, aggressive wheel designs. It is honest, loud, and incredibly well-executed.
Why We Love This Build
This TSX hits different. The way the white Cosmis-Racing wheels contrast against the clean body lines makes the car look like it belongs on a drift circuit in Japan. We watched it roll through the parking lot, and the deep concave profile of the rear wheels drew every set of eyes in the area. It is rare to see a sedan slammed this hard while still maintaining a cohesive, aggressive silhouette.
We love that the owner didn't play it safe. They went for the extreme width and the bold finish to make a statement. Every time the light catches the paint, the car looks like a piece of art. This is the kind of build that reminds us why we fell in love with car culture in the first place. You need this look.

Before You Buy: Fitment Checklist
We talk to Acura TSX Base owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×9.5 / 18×11-inch wheels fit my Acura TSX Base? 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 TSX Base owners run 18×9.5 / 18×11-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
