How to Make a Subaru Crosstrek Faster

Are you looking to boost your Subaru Crosstrek’s performance? Whether you want to improve your vehicle’s acceleration or overall speed, there are a variety of modifications you can make to achieve your desired result. In this guide, we’ll explore the steps you can take to make your Subaru Crosstrek faster.

Key Takeaways

  • Subaru Crosstrek owners can improve their vehicle’s performance by making modifications to the engine, exhaust system, suspension, and tires.
  • Aftermarket parts, such as cold air intakes, exhaust systems, and performance chips, can increase horsepower and torque.
  • A suspension upgrade can improve handling and cornering, while performance tires can improve traction and grip.
  • It’s important to consider your budget and goals when making modifications to your vehicle.

Engine Modifications

One of the most effective ways to increase your Subaru Crosstrek’s speed is to make modifications to the engine. Aftermarket parts, such as cold air intakes, exhaust systems, and performance chips, can increase horsepower and torque.

Cold Air Intake

A cold air intake system can help your engine breathe better, resulting in increased horsepower and torque. A cold air intake works by replacing the stock air intake system with a larger and more efficient intake that pulls in cold air from outside the engine bay.

Exhaust System

Upgrading your Crosstrek’s exhaust system can also improve performance. A high-performance exhaust system can increase horsepower and torque by reducing backpressure and allowing for better airflow.

Performance Chips

A performance chip, also known as an engine tuner, is a small computer module that can be plugged into the vehicle’s diagnostic port to modify its engine settings. Performance chips can increase horsepower and torque while improving fuel efficiency.

Suspension Upgrades

In addition to engine modifications, suspension upgrades can also improve your Crosstrek’s handling and cornering. Here are some suspension upgrades to consider:

Coilover suspension

Coilover suspension is a popular upgrade for performance-oriented vehicles. It replaces the stock suspension springs and shocks with adjustable units that can be fine-tuned for different driving scenarios.

Strut bars

Strut bars connect the two front struts or rear struts to provide additional stiffness to the vehicle’s body. This can improve handling and reduce body roll during cornering.

Sway bars

Sway bars, also known as stabilizer bars, reduce body roll during cornering by connecting the left and right suspension components. Upgraded sway bars can significantly improve handling and cornering.


Performance tires can also improve your Crosstrek’s speed and handling. Here are some things to consider when choosing performance tires:

Tire Size

Choosing the right tire size is important for performance. Wider tires can provide more traction and grip, but may also be heavier and negatively affect fuel efficiency.

Tire Compound

The tire compound, or rubber used to make the tire, can also affect performance. Softer rubber compounds provide better grip, but may wear out more quickly than harder compounds.

Tread pattern

Tread pattern can impact performance in different driving scenarios. Tires with a more aggressive tread pattern can provide better grip in wet or off-road conditions.

Budget and Goals

When making modifications to your Crosstrek, it’s important to consider your budget and goals. Some modifications can be costly, and it’s important to prioritize upgrades based on your needs.

For example, if you’re primarily interested in improving acceleration, engine modifications may be more important than suspension upgrades. On the other hand, if you’re interested in improving your vehicle’s handling and cornering, suspension upgrades may be a better choice.


What is the best way to make my Crosstrek faster?

The best way to make your Crosstrek faster is to make modifications to the engine, suspension, and tires. Aftermarket parts, such as cold air intakes, exhaust systems, performance chips, coilover suspension, strut bars, sway bars, and performance tires can all improve your vehicle’s speed and handling.

Will making modifications to my Crosstrek affect its warranty?

Making modifications to your Crosstrek may affect its warranty. It’s important to check with your dealership or manufacturer to understand how modifications will affect your warranty.

How much does it cost to make modifications to a Crosstrek?

The cost of modifications can vary widely depending on the type of modification and the quality of parts used. Engine modifications, such as cold air intakes and exhaust systems, can cost anywhere from several hundred to several thousand dollars. Suspension upgrades and performance tires can also be costly. It’s important to consider your budget and goals when making modifications to your vehicle.
