Unleashing the Power of your Subaru BRZ: A Comprehensive Guide to Making Your Car Faster and More Powerful!

Subaru BRZ has been known for its sports car performance and dynamic handling. However, for car enthusiasts who crave more, modifying their BRZ for speed and performance is an exciting project. This article provides a comprehensive guide on making your Subaru BRZ faster, with a focus on engine modifications, suspension upgrades, braking improvements, and other aftermarket parts and accessories.

Modifying the Engine for Improved Performance

To make a Subaru BRZ faster, the engine is the usual starting point. Some of the most popular engine modifications for improved performance include:

  • Air Intake: Replacing the factory air intake with a performance air intake can significantly increase horsepower and torque. A performance air intake system allows the engine to breathe better, resulting in more power and better throttle response.

  • Exhaust System: Upgrading the exhaust system can also enhance the engine’s performance. A high-flow exhaust system can improve the flow of exhaust gases and reduce back pressure, resulting in more power and a better sound.

  • Engine Tuning: Tuning the engine using a standalone engine management system or a piggyback ECU can optimize the air/fuel ratio and ignition timing. A well-tuned engine can produce more power and better response.

Suspension Modifications to Improve Handling and Cornering

Another essential aspect of making a Subaru BRZ faster is improving its handling and cornering. Upgrading the suspension can significantly improve the car’s stability and balance. Some of the most popular suspension modifications include:

  • Coilover Shock Absorbers: Replacing the factory shock absorbers with adjustable coilover shocks allows drivers to adjust the ride height, damping force, and spring rate. This modification can improve the car’s handling and cornering ability.

  • Sway Bars: Sway bars minimize body roll during cornering, resulting in better stability and balance. Upgrading the sway bars can significantly improve the car’s handling and cornering ability.

  • Bracing: Chassis bracing, such as strut braces, can help reduce chassis flex, resulting in better stability and handling.

Upgrades to the Brakes for Better Stopping Power

Braking upgrades are also essential for making a Subaru BRZ faster. Upgrading the brakes can improve the car’s stopping power and reduce brake fade during aggressive driving. Some popular braking upgrades include:

  • Brake Pads: Upgrading the brake pads to high-performance pads can improve the car’s braking performance and reduce brake fade.

  • Brake Rotors: Upgrading the brake rotors to slotted or drilled rotors can improve the car’s heat dissipation and reduce brake fade.

  • Calipers: Replacing the factory brake calipers with high-performance calipers can also enhance the car’s stopping power.

The Use of Performance Tires

Performance tires are another significant factor in improving a Subaru BRZ’s speed and performance. Upgrading to high-performance tires can improve the car’s grip and traction, resulting in better acceleration, cornering, and braking. Some popular performance tire options include:

  • Summer Tires: Summer tires are designed for warm weather and provide excellent grip and traction on dry roads.

  • All-Season Tires: All-season tires can handle a wider range of temperatures and road conditions than summer tires.

  • Track Tires: Track tires are designed for maximum grip and performance on the track, but are usually not suitable for daily driving.

Aftermarket Parts and Accessories that Improve Performance

In addition to the engine, suspension, brakes, and tires, there are other aftermarket parts and accessories that can improve a Subaru BRZ’s performance. Some popular options include:

  • Turbocharger Kit: Adding a turbocharger can significantly increase the engine’s power and torque output.

  • Supercharger Kit: A supercharger kit can also improve the engine’s power and torque, but usually costs more than a turbocharger kit.

  • Lightweight Wheels: Upgrading to lighter wheels can improve the car’s handling and acceleration.

  • Aero Kit: An aero kit, such as a front splitter or rear wing, can improve the car’s downforce and stability at high speeds.

Tips for Driving a Modified Subaru BRZ Safely

Finally, it’s essential to practice safe driving when pushing a modified Subaru BRZ to its limits. Always follow traffic laws and avoid reckless driving. Be mindful of the car’s speed and handling, especially on public roads. It’s also important to follow the manufacturer’s maintenance schedule and regularly inspect the car for any potential issues.


Q: How much can I expect to spend on modifying my Subaru BRZ for performance?

A: The cost of modifying a Subaru BRZ for performance can vary depending on several factors, including the specific modifications and the labor costs. However, it’s safe to assume that a comprehensive performance upgrade can cost thousands of dollars.

Q: Can I modify my Subaru BRZ without voiding the factory warranty?

A: Modifying a Subaru BRZ can potentially void the factory warranty. It’s essential to consult with a reputable performance shop or dealer to ensure that any modifications won’t void the warranty.

Q: Is it safe to modify a Subaru BRZ for speed and performance?

A: When done correctly and safely, modifying a Subaru BRZ can be safe and enjoyable. However, it’s essential to practice safe driving habits and follow proper maintenance procedures to ensure the car’s reliability and safety.
