The Best Ford Mustang Mods to Dominate the Road

Few rides scream American muscle louder than the Ford Mustang. Since tearing onto the scene in ’64, the pony has been the OG street warrior, fueling freedom and rebellion from Detroit drag strips to Hollywood blockbusters.

But the real party starts when you pop the hood. For decades, Mustang enthusiasts have customized their rides with everything from vintage Shelby power packages to modern supercharger kits, turning their stock Mustangs into snarling beasts.

Here’s your simple guide to the best Ford Mustang mods to get you started.

Cold Air Intake and Performance Exhaust

The simplest way to unlock extra power is a cold air intake kit (CAI). A CAI allows the engine to get colder and denser air for better combustion, freeing up noticeable power, especially in V8 Mustangs. Some kits play nicely out of the box; others need an ECU tune. Pairing your CAI with a proper tune unlocks the max horsepower.

Next up, ditch the restrictive factory piping and drop in a cat-back exhaust system. A good cat-back will give you some performance gains, but the most fun part is the satisfyingly aggressive roar you'll get from a performance exhaust. A cat-back exhaust system replaces any piping after the stock catalytic converter for a more straightforward route for the exhaust gases.

A freer exhaust route and dense air help your Mustang's engine breathe easier and produce more horsepower, with the added bonus of a sweet rumbling sound.

Performance ECU Tuning

ECU tuning is essential when you tinker with bolt-on performance mods. A custom professional tune allows the engine to operate at its peak performance by optimizing fuel mapping, air/fuel ratio, ignition timing, and boost pressure if you have an EcoBoost Mustang.

ECU tuning maximizes horsepower gains from other modifications, improves throttle response, ensures reliable power, and sometimes even helps with fuel economy. Whether you rock a plug-and-play piggyback, flash tuner, or full standalone ECU with bespoke software, a killer tune is the secret sauce of the best Ford Mustang mods.

Bolt-On Supercharger Kits

Now if you're after seriously big power, this is the way to go. A supercharger kit is an all-around package that gives you an insane power boost across the whole RPM range. A supercharger is driven through the belt drive on your Mustang's motor to force a greater amount of air into the engine.

Many reputable brands offer supercharger kits for anything from an S197 to the latest S650 Mustang. Depending on the kit and your Mustang version, 50-90% horsepower gains over stock are possible. You can customize your supercharger setup by selecting smaller pulleys or different ECU tuning to increase the boost pressure for more power, or decrease it for a smoother delivery.

Rolling Gear: Suspension, Brakes, Wheels, Tires

All that power and no control? No bueno. Sort these out, too, and you'll have a complete canyon or track slayer.

Suspension Mods

A set of lowering springs is the first step. They drop your Mustang's center of gravity for better handling, reduced body roll, and a killer-looking lowered stance. Depending on your driving needs (track, street, etc.), you can get linear or progressive springs.

Linear springs offer consistent handling characteristics on every surface, and progressive rate springs adjust their stiffness based on the driving condition. Pair them with quality shocks and struts, or go full-adjustable with a coilover kit that comes as a unit of shocks and springs that are height and damping adjustable.

Upgrade the sway bars (also known as anti-roll bars) for perfect handling. Sway bars connect the left and right sides of the suspension components and reduce excessive body roll. You can get beefier bars for more stabilization, and adjustable ones offer a customizable, responsive, and planted driving characteristic.

Braking Mods

With all the added horsepower (especially after a significant power boost from a supercharger), you'll also need a boost in stopping power. Stock brake pads, lines, and fluid cause fade under hard driving. Worn brake rotors cause a mushy pedal feel and reduced stopping power. Upgrade to performance pads, stainless steel brake lines, performance-grade fluid, and bigger slotted/drilled discs/rotors for constant stopping power under any kind of spirited driving.

Wheels and Tires

Bigger wheels are the single most satisfying upgrade you can make, looks-wise, especially after lowering your Mustang. A set of bigger, lighter wheels also reduces unsprung weight and helps with better cornering. Wrap them up with sticky performance rubber, and you'll have the agile handling capability that perfectly complements the power increase.
