Wheels: The Foundation of Style and Performance

One of the most impactful modifications, both visually and functionally, is upgrading your wheels. Racers and enthusiasts alike often prioritise new wheels not just for their aesthetic appeal but also for their performance benefits. Reducing rotational mass is key, as lighter wheels can improve acceleration, braking, and handling dynamics, making your car feel more nimble and responsive.

The Subaru BRZ's wheel specifications are fairly common, featuring a 5x100 bolt pattern. Available diameters typically range from 17 to 20 inches, with widths varying from 7.5 to 10.5 inches. When choosing new wheels, ensuring correct offset and fitment is paramount to avoid rubbing and maintain proper suspension geometry.

A popular choice among BRZ owners for its balance of lightness, strength, and affordability is the Enkei RPF1 rim. These wheels are renowned in the aftermarket world and are available in various finishes, including black, white, and silver. Their lightweight yet durable construction makes them an excellent upgrade for both track-focused builds and spirited daily driving.

Complementing your new wheels with high-performance tyres is equally crucial. For a sturdy and reliable change that can enhance safety even on challenging roads, options like the Michelin Pilot Sport AS4 are highly regarded. These tyres provide excellent grip in various conditions, offering a significant upgrade over standard factory rubber.

Key Wheel Considerations:

• Weight: Lighter wheels reduce unsprung mass, improving handling and acceleration.
• Material: Forged wheels are typically lighter and stronger than cast wheels, but also more expensive.
• Size & Offset: Ensure proper fitment to avoid issues with suspension or bodywork.
• Tyre Choice: Match your tyres to your driving style and the performance capabilities of your new wheels.

Brakes: Prioritising Your Safety and Control

While the Subaru BRZ's factory brakes are competent for everyday driving, pushing the car on track or through demanding conditions quickly highlights the need for an upgrade. For a sports car capable of high speeds, superior braking performance is not just an enhancement; it's a critical safety measure. Upgrading your braking system ensures consistent stopping power, reduces brake fade, and provides greater confidence behind the wheel.

There are several avenues for improving your BRZ's braking capabilities:

1. Performance Brake Pads

Upgrading your brake pads is often the first step due to its relatively low cost and significant impact. Performance pads offer higher friction coefficients, better heat resistance, and improved bite. Top aftermarket options available in the market include those from StopTech and Hawk HPS, both known for their reliable street and light track performance.

For dedicated track use, specialised racing brake pads are available. For the FRS/BRZ, Project Mu, in collaboration with Gazoo Racing, has developed compounds like the RSF01A for the front and RSR02 for the rear. It is absolutely crucial to note that these specific Project Mu pads are designed exclusively for track use and are explicitly not recommended for street driving. Their aggressive compound may not perform optimally at lower temperatures and could be detrimental to road safety and comfort. They are best paired with high-performance track tyres for optimal results.

2. Upgraded Rotors

Replacing your brake rotors can dramatically improve your BRZ's braking performance and heat management. Depending on your specific needs, you can choose between different types:

• Drilled Rotors: Featuring holes drilled into the rotor surface, these are very effective at cooling down heat generated during heavy braking. They also help to dissipate gasses and dust.
• Slotted Rotors: Characterised by slots cut into the rotor face, these assist in sweeping away gasses and dust generated by the brake pads, maintaining consistent contact and reducing fade.

Both types offer advantages over standard plain rotors, enhancing braking feel and longevity under stress.

3. Big Brake Kits (BBK)

For the ultimate braking upgrade, a Big Brake Kit (BBK) is the answer. A good BBK significantly enhances braking performance by increasing the surface area of the brake pad that contacts the brake rotor, often incorporating larger calipers with more pistons and significantly larger rotors. This results in superior heat dissipation, reduced fade, and a much more powerful and consistent pedal feel, essential for track driving or highly modified vehicles.

Suspension: Master Your Car's Dynamics

For those who crave precision handling and a more engaging driving experience, suspension modifications are paramount. A well-tuned suspension system allows you to navigate corners with greater confidence, maintain composure over varying road surfaces, and ultimately shave seconds off lap times. With the right suspension setup, you can truly unlock your BRZ's potential and feel like a champion on the road.

The primary suspension modifications include:

• Coilovers: These are integrated spring and damper units that allow for adjustable ride height and often adjustable damping (stiffness). Coilovers provide the most comprehensive control over your car's handling characteristics, enabling precise tuning for track or street use.
• Lowering Springs: A simpler and more cost-effective way to lower your car's centre of gravity, reducing body roll and improving aesthetics. While they use the factory dampers, they offer a noticeable improvement in handling.
• Air Suspension: Offering ultimate adjustability, air suspension allows you to raise or lower your car at the touch of a button. This system provides excellent ride comfort for daily driving while still allowing for aggressive lowering for show or performance.
• Sway Bars (Anti-Roll Bars): These components connect the left and right sides of the suspension, reducing body roll during cornering. Upgraded sway bars can significantly flatten your car's cornering attitude, improving stability and responsiveness.

Combining these modifications can transform your BRZ's handling, making it incredibly agile and responsive.

Headers: Unleashing More Power

For those seeking to extract more power from their BRZ's naturally aspirated engine, a new set of headers is a highly effective modification. Headers are designed to efficiently direct exhaust gases away from the cylinder head and runners to a collector. By improving exhaust flow, headers reduce back pressure, allowing the engine to breathe more freely and produce more power, particularly in the mid to high rev range.

There are generally two types of headers to choose from:

• Equal Length Headers: These are designed with primary tubes of equal length for each cylinder, aiming to create a more consistent exhaust pulse and improve scavenging. Equal length headers are generally better at accumulating power throughout the rev range and can produce a smoother, higher-pitched exhaust note.
• Unequal Length Headers: These headers have primary tubes of varying lengths, often mimicking the factory design. They can produce a distinctive 'boxer rumble' exhaust note, which many Subaru enthusiasts appreciate. While they might not offer the same peak power gains as equal length headers, they still provide a significant improvement over stock.

An example of a highly regarded header option is the ACE Type-A 350, especially when tuned by specialists like Delicious Tune, known for optimising the power delivery for the BRZ platform.

Exhaust Systems: Sound and Performance

Beyond headers, the rest of your exhaust system plays a vital role in both performance and sound. A standard Subaru BRZ features a cat-back exhaust system, which includes a mid-pipe, muffler, and two exhaust tips. Replacing this with an aftermarket unit can yield significant benefits.

Aftermarket exhaust systems typically feature straighter and wider piping compared to the restrictive factory setup. This improved flow reduces back pressure, allowing the engine to expel exhaust gases more efficiently and thus generate more power. Furthermore, an aftermarket exhaust system will transform your BRZ's auditory experience, offering a deeper, more aggressive, or more refined exhaust note, depending on the system chosen.

The Perrin BRZ Exhaust System is a great example of a highly regarded replacement. It's known for providing additional airflow, which helps your car gain more power, and can complement forced induction setups if you decide to go that route in the future.

Remapping ECU: Smart Power Gains

The Engine Control Unit (ECU) is the brain of your car, regulating crucial engine parameters such as the fuel and air mixture, ignition timing, and turbocharger boost (if applicable). A correctly remapped ECU can unlock significant performance gains and introduce new functionalities.

Specialist tuners can rewrite the software on your ECU using platforms like Openflash or EcuTek. A well-executed remap can lead to:

• More Power: Optimised fuel and ignition timing for increased horsepower and torque.
• Improved Fuel Economy: More efficient engine operation under cruising conditions.
• Enhanced Features: Many modern remaps can sync with your phone for real-time data monitoring and activate advanced functions such as launch control, flat-foot shifting, and setting per-gear rev limits, offering a truly customisable driving experience.

ECU remapping is a sophisticated process that should only be performed by experienced professionals to ensure engine reliability and optimal performance.

Turbocharging: Unleashing Enormous Power

It's a common point of discussion among enthusiasts: the 2022 Subaru BRZ does not come with a turbocharger as standard. However, this doesn't mean you can't add one! Installing an aftermarket turbocharger or supercharger kit is arguably the most significant modification for achieving enormous power increases.

For those truly seeking supercar levels of performance, a complete Motorsports Kit Stage 2 (or similar comprehensive forced induction package) can transform your BRZ. These systems are engineered to provide substantial power bumps, with some setups capable of supporting well over 700 horsepower with subsequent engine modifications and tuning. This level of modification typically requires significant supporting upgrades to the engine internals, fuel system, and cooling to ensure reliability and longevity.

Aerodynamics: Form Meets Function

Aerodynamics plays a crucial role not only in a vehicle's appearance but also in its fuel efficiency and high-speed stability. Every car manufacturer invests heavily in designing vehicles with a low coefficient of drag (Cd). For aftermarket enthusiasts, aerodynamics offers a way to enhance both the visual aggression and the functional performance of their BRZ.

With a vast array of options available in the marketplace, you can transform your BRZ into an extreme track machine or a stylish street cruiser. Aerodynamic modifications typically include:

• Front Splitters: Reduce lift at the front of the car and direct airflow for cooling.
• Side Skirts: Smooth airflow along the sides of the vehicle, reducing drag.
• Rear Diffusers: Manage airflow exiting the underside of the car, improving downforce.
• Spoilers & Wings: Generate downforce at the rear, enhancing high-speed stability and grip.

One highly popular and distinctive suggestion for an aerodynamic overhaul is the Rocket Bunny kit. These wide-body kits are designed to dramatically highlight and exaggerate key elements of the automobiles they match, such as the fenders, lips, and spoilers. A Rocket Bunny kit not only gives your BRZ an incredibly aggressive and unique stance but can also accommodate wider wheels and tyres for improved handling.
