About This Honda Civic Si 2013 Build
We love featuring real builds from real owners. This Honda Civic Si 2013 sits on a set of 18×8.5 / 18×8.5-inch NLMotoring Six1 wheels, and the result speaks for itself.
The owner chose NLMotoring for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Honda Civic Si builds come through WheelFront every month, but this one stands out. The combination of the exterior with the NLMotoring Six1 creates a look that balances aggression with elegance.

Fitment Breakdown: NLMotoring Six1 on the Honda Civic Si 2013
I walked up to this 2013 Civic Si and immediately checked the wheel choice. The NLMotoring Six1 wheels in 18x8.5 with a +35 offset sit right where they need to be. This square setup keeps the handling predictable and makes rotation easy for the track days.
The +35 offset pushes the face of the wheel out perfectly toward the edge of the fender. You get that aggressive stance without needing massive spacers to clear the factory brake calipers. It fills the wheel wells without looking like a monster truck.
The hub bore on these wheels mates up clean to the Civic platform. We always double-check these tolerances to ensure there is zero vibration at highway speeds. A tight fit here keeps the steering feel sharp and responsive.
I looked closely at the spoke design and noticed how it arcs to clear the Si brake setup. You do not have to worry about hitting the caliper housing or the outer cooling fins. It clears the hardware with enough room to breathe on hot days.

The coilovers on this build really change the game for fitment. By dropping the car, we tucked the top of the tire just inside the fender lip. This creates a mean silhouette that makes the 18-inch diameter look purposeful.
Be careful if you decide to go any lower than this specific setup. The inner plastic fender liners will start to fight back if you take a corner too hard. I recommend a slight roll of the rear fenders if you plan to carry passengers often.
The barrel lip depth on the Six1 provides just enough detail to catch the eye. It is not overly deep, but it adds a layer of depth that stock wheels simply lack. The proportions highlight the compact nature of the 2013 chassis perfectly.
What We Recommend for Honda Civic Si 2013 Owners
If you own an Si, stick to an 18-inch wheel for the best balance of looks and performance. Going up to 19s usually ruins the ride quality and adds too much unsprung weight. We have tested this range extensively and 18s win every time.

For offsets, keep your numbers between +35 and +42 for a flush look. Anything lower than +35 starts to poke too much and invites paint chips from road debris. You want the wheels to frame the car, not overpower the body lines.
Always run a square setup on this front-wheel-drive platform. Staggered wheels on a Civic Si just create unnecessary understeer and make the car feel sluggish in the turns. Keep the footprint even at all four corners for maximum grip.
Do not be afraid to run a light tire stretch if you want to dial in the stance. A 225/40/18 tire usually offers the best clearance without looking like a rubber band. It protects the wheel lip while keeping the sidewall stiff enough for spirited driving.
Avoid cheap spacers if you can possibly help it. High-quality hub-centric spacers are fine, but getting the right offset from the start is always the smarter move. Bolt-on wheels that fit right the first time keep your wheel bearings happy.

Style and Build Analysis
The bronze finish on these Six1 wheels pops hard against the factory paint. Bronze is a timeless choice that bridges the gap between race-inspired aggression and street style. It catches the sunlight and adds warmth to the entire car's profile.
The six-spoke design feels like a nod to classic Japanese tuner culture. It looks simple, clean, and intentional. I prefer this style over complex multi-piece wheels that just get covered in brake dust anyway.
Stance is about more than just height; it is about how the wheel fills the gap. These wheels sit flush with the fenders, creating a sense of balance that the stock car lacks. It looks like a factory performance special that Honda should have built.
This build feels cohesive because every modification serves a purpose. The wheels do not shout for attention, but they demand a second look. It is an honest build that celebrates the chassis rather than trying to hide it.
Comparing this to other builds we see at the shop, this one wins on simplicity. Many owners over-modify their Si and ruin the driving dynamics. This owner kept it tight, classy, and ready for the street.
Why We Love This Build
This Civic Si grabs your attention the moment it rolls into the lot. The bronze NLMotoring wheels glow under the streetlights, perfectly filling the arches with that aggressive +35 offset. It is the kind of build that makes you stop mid-sentence just to admire the clean lines and the purposeful stance.
We love the honesty of this car. It does not try to be a track monster with giant wings or a stance queen with unreadable camber. It is just a well-sorted, daily-driven machine that looks exactly how an Si should look from the factory. This build proves that the right wheels and a proper coilover setup change everything. Grab a set and see for yourself.

Before You Buy: Fitment Checklist

We talk to Honda Civic Si owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×8.5 / 18×8.5-inch wheels fit my Honda Civic Si? 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 Honda Civic Si owners run 18×8.5 / 18×8.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
