Can you modify a Subaru BRZ?
Yes. The Subaru BRZ can be modified in a wide range of ways, from bolt-on intake and exhaust to ECU tuning and forced induction. Modifications can improve performance and handling, but buyers should consider warranty, emissions compliance, insurance, and long-term reliability.
Common ways BRZ owners modify their cars
Power, handling, and aero upgrades
Enthusiasts typically pursue performance, handling, and aesthetics. The following categories cover the most common upgrade paths for the BRZ.
- Bolt-on intake systems and performance filters
- Cat-back or turbo-back exhaust systems
- ECU tuning and remapping (e.g., open-source or vendor-provided tunes)
- Forced induction upgrades (turbochargers or superchargers) with supporting hardware
- Suspension upgrades (coilovers, springs, sway bars, adjustable endlinks)
- Braking upgrades (high-performance pads and rotors, upgraded lines)
- Wheels and tires (lighter wheels and high-performance tires)
- Drivetrain improvements and transmission enhancements (short-throw shifters, limited-slip differential options where applicable)
- Aerodynamic and cosmetic enhancements (front splitters, rear spoilers, body kits, graphics or wraps)
Note that compatibility depends on model year and trim, and some parts may affect warranty or emissions; always verify fitment and local rules before purchase.
Considerations before modifying
Warranty, legality, and reliability
Before making upgrades, owners should weigh warranty coverage, emissions legality, reliability, insurance implications, and the overall cost of ownership. The following points help set expectations for BRZ modification projects.
- Warranty and service implications: Many aftermarket parts can affect coverage; some dealers may still honor warranties for non-related failures, but this varies by region and policy.
- Emissions and legality: Street-legal status depends on the part and place; some tuning or exhaust options may require certifications or inspections.
- Reliability and risk: Increased power and aggressive setups demand robust cooling, fuel, and lubrication planning; monitor temps and maintenance intervals.
- Insurance impacts: Modifications can alter premiums or coverage; discuss changes with your insurer and keep documentation.
- Budgeting: Plan for installation, tuning, tires, maintenance, and potential upgrades as the car evolves.
- Professional installation: Especially for power or drivetrain work, professional setup and dyno tuning help maximize safety and performance.
A practical approach is to stage upgrades gradually—start with non-invasive bolt-ons, then address handling and braking, and only pursue engine or forced-induction work after thorough research and professional advice tailored to your year and model variant.
Factory options and official guidance
Official parts and regional availability
Subaru and Toyota offer official performance-oriented components and guidance for BRZ owners, designed to balance performance with reliability and emissions considerations. Availability can vary by market and trim.
- Official accessories and performance parts from Subaru/Toyota dealers (aero parts, suspension enhancements, braking improvements) designed to be compatible with the warranty framework.
- OEM-compatible replacements and upgrades (tires, wheels, brakes, bushings) that preserve factory reliability and service support.
- Engineering limits and compatibility: The FA24-based BRZ engine family has specific cooling and fuel requirements; aftermarket forced induction requires careful tuning and supporting hardware.
- Regional differences: Markets differ in what parts are offered and permitted; check local catalogs and dealer guidance.
Consult an authorized dealer or trusted performance shop for guidance on part compatibility and installation to protect warranty and ensure performance gains are realized safely.
Summary
The Subaru BRZ is a popular platform for enthusiasts to modify. Owners can improve power, handling, and aesthetics through a mix of bolt-on parts, suspension and braking upgrades, and ECU tuning. Plan upgrades carefully to preserve reliability, stay within local regulations, and ensure proper installation and tuning; a phased, professional approach is recommended.
What year to avoid Subaru BRZ?
2013
Subaru BRZ years to avoid and common problems
When the BRZ was first released in 2013, drivers noticed that the valve springs were prone to failure, causing engine stalling. The NHTSA issued a recall, but not before multiple car owners had been stranded on the highway and paid thousands of dollars for engine repairs.
Can you modify a BRZ?
The Subaru BRZ is already a fantastic handling car right from the factory, but there's always room for improvement. Upgrading your suspension and chassis components is how you translate engine power into faster lap times and more confident cornering on your favorite back roads.
Can you make a Subaru BRZ faster?
By upgrading to a performance-oriented BRZ Exhaust system, you open up the pathway for gasses to escape more efficiently. This not only improves the engine's breathing but also increases horsepower and torque. A better exhaust system means less backpressure and more power being delivered to the wheels.
