The S650 Mustang is a digital masterpiece. It is the most advanced pony car Ford has ever rolled off the assembly line. But for those of us who grew up watching Fox Bodies dominate the drag strips and the street scene in the late ‘80s and early ‘90s, there is a certain "raw" aesthetic that the new screens and sharp lines can’t quite capture on their own.
At DTX Performance, we live for the intersection of heritage and high performance. You don't have to choose between modern tech and classic soul. You can build a bridge. If you want to pay homage to the "Four-Eye" or the "Aero-Fox" era while keeping your 2024+ performance levels, this is your blueprint.
Push the boundaries. Build your legacy. Select the parts that matter.
Build the Stance: Lowering Springs and Spacers
The Fox Body was famous for its aggressive, nose-down rake. It looked like it was leaning into a fight even when it was parked. The factory S650, while handling brilliantly, often sits a bit too high for that classic "street king" profile.
To get the look right, you need to eliminate the wheel gap. A set of high-performance lowering springs is your first move. This isn't just about looks; lowering the center of gravity improves turn-in and reduces body roll during hard acceleration.
Action Steps:
- Select Lowering Springs: Look for a 1.0” to 1.5” drop to mimic the slammed Fox Body stance.
- Add Wheel Spacers: Fox Bodies were known for their "fat" rear tire look. Pushing your S650 wheels out to the fender edge with precision spacers creates that wider, more planted appearance.

Select the Footwork: Retro-Inspired Wheels
Nothing defines an era like the wheels. The Fox Body era was dominated by the "Phone Dial," the "Ten-Hole," and eventually the iconic five-spoke Cobra R design. While the S650 comes with impressive alloy options, they lean heavily into the "spider-web" or multi-spoke modern aesthetic.
To flip the script, look for modern wheels that utilize a heavy five-spoke design. Think thick, meaty spokes with a deep concave or a machined lip. A silver or chrome finish can also break up the modern trend of all-black wheels, instantly giving your S650 a more "period-correct" feel from the 1990s.
Pro Tip: If you are running high-performance brakes, ensure your wheel selection offers enough clearance. A classic look shouldn't compromise your stopping power. Check out our performance brake options to match your new wheels: https://dtxperformance.com/sitemap_products_5.xml.
Push the Stealth: Smoked Lighting and Trim
The LX Fox Body was the sleeper of choice because of its stripped-down, monochromatic look. It ditched the chrome and the extra fluff for a streamlined, aggressive face. You can replicate this on the S650 by focusing on your lighting and trim.
The S650’s LED headlights are incredibly bright, but the clear housings scream "future." By adding high-quality smoked overlays or tinted marker lights, you bridge the gap back to the smoked-out headlight covers that were a staple of every modified Mustang in 1992.
Key Aesthetic Upgrades:
- Smoked Tail Light Tints: The S650’s three-bar design is a direct descendant of the early Mustangs. Darkening the housings emphasizes the glow and hides the plastic when the lights are off.
- Amber Marker Delete: Swap the bright amber side markers for clear or smoked units to clean up the front fenders, mimicking the clean lines of an LX notchback.

Build the Aero: Rear Spoilers and Louvers
The Fox Body GT was famous for its "cheese grater" taillights and its prominent rear wing. While we don't recommend putting a 1988 wing on a 2024 trunk, you can take inspiration from the scale and placement.
A prominent rear spoiler: specifically one that extends over the edges of the trunk: gives the S650 a much more substantial rear profile. If you want to go full "throwback," consider rear window louvers. While controversial to some, nothing says "Classic Muscle" quite like a set of matte black louvers. They provide shade, privacy, and an unmistakable 80s silhouette.
Action-Oriented Styling:
- Decklid Spoilers: Choose a design that is angular rather than curved.
- Front Splitters: A simple, black matte front splitter echoes the chin spoilers found on the classic GT models.
We promise to only send you good things, so we only stock aero parts that can actually handle the downforce your S650 generates. Explore the catalog here: https://dtxperformance.com/sitemap_products_8.xml.
Shop the Sound: High-Performance Air Intake
The Fox Body 5.0 had a very specific "grunt." It was a combination of that pushrod low-end rumble and the heavy induction noise when the throttle plate snapped open. While the S650's Coyote engine is a DOHC masterpiece that loves to rev, you can bring back that aggressive induction "suck" with a high-performance cold air intake.
A dual-intake setup on the S650 is a marvel of engineering, but swapping to high-flow filters and smoothed-out intake tubes allows the engine to breathe: and sound: more like the unrestricted beasts of the past.
Why it works:
- Increased Throttle Response: Getting air in faster means moving faster.
- Aggressive Engine Note: It adds a layer of "mechanical" sound that matches the throwback aesthetic.
- Performance Gains: More oxygen equals more power. Simple math.
