Engine Upgrades
Upgrading the engine is one of the most common ways to enhance the performance of your Focus ST. Options include aftermarket turbochargers, fuel injectors, and engine control units (ECUs). High-performance parts from brands like www.cobbtuning.com and mountuneusa.com are designed to maximize horsepower and torque, providing a noticeable boost in acceleration.
Turbo Kits
Aftermarket turbo kits can significantly increase your Focus ST’s power. Brands like STM Tuned Inc. offer comprehensive kits that include everything needed for installation. Consider options such as the BNR ST67 Turbocharger, which is designed for stock fuel systems and can produce 400-420 WHP.
ECU Tuning
ECU tuning adjusts the factory settings of your engine’s computer to unleash more power. Companies like Steeda and CJ Pony Parts provide tuning solutions that ensure your car runs efficiently while maximizing performance.
Exhaust Systems
A performance exhaust system not only enhances the sound of your Focus ST but also improves exhaust flow, which can lead to increased power. Various brands such as www.stage3motorsports.com and www.lethalperformance.com offer high-quality options tailored for the Focus ST.
Cat-Back Exhausts
Cat-back exhaust systems replace everything from the catalytic converter back. They typically provide a performance increase due to better flow characteristics and a more aggressive tone.
Downpipes
Replacing the factory downpipe with a high-flow option can significantly reduce turbo lag and increase horsepower. These parts work best when paired with a complementary exhaust system.
Air Intake Systems
An aftermarket cold air intake system can improve airflow to your engine, resulting in better throttle response and increased power. Brands such as www.speedperf6rmanc3.com and JST Performance offer a variety of intake solutions specifically designed for the Focus ST.
Benefits of Cold Air Intakes
A cold air intake lowers the intake air temperature, allowing for denser air to enter the engine. This results in a more efficient combustion process, ultimately leading to improved performance.
Suspension Kits
Upgrading your suspension is crucial for improving handling dynamics. Performance suspension kits can lower your Focus ST, reduce body roll, and enhance cornering capabilities. Look for options from reputable brands like mountuneusa.com and www.steeda.com.
Coilover Kits
Coilovers allow for adjustable ride height and damping settings. This flexibility helps you tailor your Focus ST’s handling characteristics to your driving style, whether on the track or the street.
Sway Bars
Upgrading sway bars can reduce body roll during cornering, providing a more stable and responsive driving experience.
Brake Upgrades
For those who push their Focus ST to the limits, upgrading the braking system is essential. Enhanced brake components can provide better stopping power and improved safety. Companies like performanceparts.ford.com and STM Tuned Inc. offer quality brake upgrades.
Brake Pads and Rotors
High-performance brake pads and rotors can withstand higher temperatures and provide improved grip, ensuring consistent performance during spirited driving.
Wheels and Tires
The right wheels and tires can dramatically affect your Focus ST’s handling and performance. Lightweight wheels reduce unsprung weight, while performance tires improve grip. Performance parts retailers like www.cjponyparts.com and www.lethalperformance.com offer a wide selection to choose from.
Tire Selection
Choosing the right tires for your Focus ST depends on your driving style. Summer tires provide the best grip in dry conditions, while all-season tires offer versatility for varying weather.
