About This Ford Mustang GT 2013 Build
We love featuring real builds from real owners. This Ford Mustang GT 2013 sits on a set of 19×8.5 / 19×8.5-inch RTX Slick wheels, and the result speaks for itself.
The owner chose RTX for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Ford Mustang GT builds come through WheelFront every month, but this one stands out. The combination of the exterior with the RTX Slick creates a look that balances aggression with elegance.
Fitment Breakdown: RTX Slick on the Ford Mustang GT 2013
I walked around this Mustang at the last show and immediately noticed the stance. Running 19x8.5 RTX Slicks at all four corners creates a clean, uniform look. That 42 offset pulls the wheels in just enough to keep them tucked under the fenders.
The S197 platform loves a square setup like this for daily drivability. You get plenty of meat on the road without the headache of staggered tire sizes. Handling feels predictable and sharp through the corners.
We checked the clearance on those factory calipers and they clear without issue. The spoke design on the Slick gives you plenty of breathing room for the stock brakes. You won't need spacers to keep your rotation clear.
The hub bore sits perfectly on the 2013 Mustang hub. We hate using hub-centric rings if we can avoid them, and here we don't have to. Everything bolts up tight and runs true at highway speeds.
These lowering springs drop the car right over the tires. We saw a tight gap that eliminates that unsightly wheel well void. It looks aggressive without being slammed into the pavement.
You need to watch out for the inner fender liner if you take tight corners at speed. We saw zero rubbing during our test drive, but stay away from oversized sidewalls. Keep your tire profile moderate to save your paint.
The barrel lip depth on this 19-inch setup provides a solid profile. It isn't a deep-dish rim, but the spokes carry enough weight to look substantial. This design respects the classic Mustang lines while adding a modern touch.
What We Recommend for Ford Mustang GT 2013 Owners
If you want a daily driver that turns heads, stick to the 19-inch diameter. It strikes the perfect balance between ride quality and aesthetic impact. Don't go to 20s unless you want a stiffer, harsher ride.
We tell everyone to aim for an offset between 35 and 45 for the S197. That range keeps the scrub radius manageable and the steering feedback tight. Anything lower than 30 will poke too far and kill your fenders.
A square setup like this makes tire rotations a breeze. You can keep your rubber fresh for thousands of extra miles. Save the staggered setups for the guys who spend every weekend at the drag strip.
Watch your tire width carefully on an 8.5-inch wheel. We recommend a 245 or 255 width for the best sidewall profile. Anything wider will bulge and look sloppy on the road.
Avoid the temptation to stack spacers just to get a wider look. You will sacrifice your wheel bearings and ruin your suspension geometry. Keep the fitment clean, tight, and functional instead.
Style and Build Analysis
The Black Machined finish hits different under the sun. The dark paint hides brake dust, while the machined accents catch the light during every rotation. It looks premium without screaming for too much attention.
These RTX Slicks feature a sharp, multi-spoke geometry that complements the Mustang’s body. The car looks muscular and planted, like it wants to hunt down the next light. The proportions feel right at home with the aggressive 2013 styling.
We see a lot of builds that go overboard with gaudy chrome or cheap matte paint. This build keeps it classy with high-contrast surfaces. It feels like something the factory should have offered on a special edition trim.
The stance defines the entire character of this machine. With the lowering springs, the tires sit flush enough to command respect. It looks fast even when it’s just idling in the parking lot.
Compared to other builds we have featured, this one prioritizes balance. It doesn't need aggressive camber or stretched tires to look finished. It is a masterclass in clean, street-friendly modification.
Why We Love This Build
This Mustang sits perfectly, with the Black Machined RTX Slicks catching the light every time the car moves. The drop from the springs closes the gap just enough to give it that predatory, track-ready look. We love how it stays true to the Mustang spirit while modernizing the whole profile.
When you see this car rolling down the street, you stop and look. It is simple, effective, and undeniably cool. It proves that you don't need a crazy wide-body kit to build a serious head-turner. This is exactly how a daily driver should look.
This build is pure automotive perfection.

Before You Buy: Fitment Checklist
We talk to Ford Mustang GT owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 19×8.5 / 19×8.5-inch wheels fit my Ford Mustang GT? 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 Mustang GT owners run 19×8.5 / 19×8.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
