Mustang Performance Upgrades Kansas City

Most Mustang GT owners start with a cold air intake and cat-back exhaust — these are bolt-on modifications that improve throttle response, add horsepower, and give your Mustang an aggressive sound. A cold air intake from JLT or K&N typically adds 10-20 horsepower and is one of the easiest installs. Pair it with a quality exhaust system for the biggest bang-for-buck improvement. From there, lowering springs and upgraded brakes are popular next steps. Call American Fusion Wheels at 913-291-2027 and we will help you build a mod plan for your budget.

Lowering springs are not required, but they are one of the most popular modifications for the S550 and S650 Mustang. A 1 to 1.5 inch drop eliminates the factory wheel gap, improves handling by lowering the center of gravity, and gives the car a much more aggressive stance. Eibach Pro-Kit provides a moderate 1-inch drop with progressive spring rates for daily comfort, while Eibach Sportline and BMR springs offer a more aggressive 1.5-inch drop for drivers who prioritize handling. We recommend a wheel alignment after any lowering spring installation.

A cold air intake on a Mustang GT (5.0L Coyote) typically adds 10 to 20 horsepower at the wheels, with the biggest gains in the upper RPM range. The real improvement is in throttle response and intake sound — the Coyote engine sounds incredible with an open-element intake. JLT, K&N, and Airaid are the most popular brands for Mustangs. On the EcoBoost 2.3L, a cold air intake combined with an intercooler upgrade can yield even more noticeable gains. Our team installs intakes daily — call 913-291-2027 for pricing.

Yes. American Fusion Wheels installs supercharger kits from Whipple, Roush, VMP Performance, and ProCharger on the Mustang GT (5.0L Coyote). A Whipple or VMP twin-screw supercharger kit can push your GT past 700 horsepower with supporting modifications like fuel system upgrades, heat exchangers, and a professional tune. Centrifugal options from ProCharger are available at a lower price point. Supercharger installs are major projects — call us at 913-291-2027 to discuss your goals and get a detailed quote.

For track use, we recommend upgrading to a big brake kit from Brembo, Baer, or StopTech. These kits feature larger rotors and multi-piston calipers that dissipate heat better and resist brake fade during extended track sessions. Power Stop Z26 kits are a great mid-range option for spirited street driving and occasional track days. For serious track builds, StopTech Trophy kits and Baer Extreme systems offer the most stopping power. Pair any brake upgrade with high-temperature brake fluid and performance brake pads for the best results.

Yes, and we strongly recommend it. Lowering springs change your Mustang's camber, caster, and toe angles. Without an alignment, you will experience uneven tire wear and the car may pull or feel unstable. We perform alignments on our precision alignment rack after every suspension modification — lowering springs, coilovers, sway bars, and strut upgrades. The alignment is typically done the same day as the spring install at our Shawnee, KS shop.

Lowering spring kits for the Mustang range from about $250 to $500 for the springs themselves. Coilover kits range from $800 to $2,500+ depending on brand and adjustability. Professional installation typically runs $300 to $600 including alignment. All-in, you can lower your Mustang on quality springs with professional installation and alignment starting around $600 to $1,000. Coilover setups with installation start around $1,200. Financing is available at American Fusion Wheels to spread the cost into monthly payments.
