The sound alone is worth it, giving the engine a more aggressive and throaty roar. However, it's crucial to ensure that the intake is properly shielded from heat to maintain optimal performance.

Exhaust Systems: Freeing Up the Flow

The exhaust system is another key area for improvement. A cat-back exhaust system, or even a full header-back system, can dramatically reduce backpressure, allowing the engine to exhale more efficiently. Brands like Fujitsubo, Invidia, and J's Racing offer high-quality exhaust systems specifically designed for the FD2 Type R. These systems typically feature larger diameter piping, mandrel bends, and less restrictive mufflers, all contributing to increased horsepower and torque. A good exhaust system not only improves performance but also enhances the car's soundtrack, adding a deeper and more aggressive tone. Remember to check local regulations regarding exhaust noise levels to ensure compliance.

Camshafts and Valvetrain: Raising the Rev Limit

For more serious power gains, consider upgrading the camshafts and valvetrain. Aftermarket camshafts, such as those from Toda Racing or Skunk2, can significantly alter the engine's power curve, shifting the power band higher in the RPM range. This allows the engine to rev even higher and produce more peak horsepower. However, upgrading the camshafts also requires upgrading the valvetrain components, including valve springs, retainers, and sometimes even valves, to ensure they can handle the increased RPM and valve lift. This is a more complex modification that requires professional installation and tuning, but the results can be truly impressive.

Suspension and Handling: Carving Corners with Precision

The FD2 Type R already boasts impressive handling from the factory, thanks to its stiff chassis and well-tuned suspension. However, there's always room for improvement, especially if you plan on tracking the car or simply want a more responsive and engaging driving experience. Enhancing the suspension and handling isn't just about making the car look good; it's about improving its overall performance and responsiveness. A well-tuned suspension system will provide better grip, reduced body roll, and improved steering feel, making the car more enjoyable to drive on both the street and the track. These modifications can significantly enhance the car's cornering ability and overall stability, giving you more confidence behind the wheel.

Coilovers: Dialing in the Perfect Ride

Coilovers are a popular upgrade for FD2 Type R owners looking to fine-tune their car's handling. Coilovers allow you to adjust the ride height and damping, giving you complete control over the car's suspension characteristics. Brands like Ohlins, KW, and Tein offer high-quality coilovers specifically designed for the FD2 Type R. With adjustable ride height, you can lower the car's center of gravity, reducing body roll and improving cornering.

Whether you prefer a comfortable ride on the street or a stiff and responsive setup for the track, coilovers provide the flexibility to dial in the perfect ride.

Sway Bars: Reducing Body Roll

Upgrading the sway bars is another effective way to improve the FD2 Type R's handling. Stiffer sway bars reduce body roll during cornering, keeping the car flatter and more stable. Aftermarket sway bars are typically thicker and more rigid than the factory bars, providing greater resistance to twisting forces. Brands like Eibach and Whiteline offer sway bar kits specifically designed for the FD2 Type R. By reducing body roll, sway bars improve the car's responsiveness and grip, allowing you to corner with more confidence. They also help to distribute weight more evenly during cornering, further enhancing stability.

Bushings: Tightening Up the Chassis

Replacing the factory rubber bushings with polyurethane or spherical bushings can significantly improve the FD2 Type R's handling. Rubber bushings tend to flex and deform under load, which can lead to sloppy handling and imprecise steering. Polyurethane bushings are much stiffer and more durable than rubber bushings, providing a more direct connection between the suspension components and the chassis. Spherical bushings offer even greater precision and reduced friction, making them ideal for track use. By replacing the bushings, you'll eliminate unwanted flex and improve the car's responsiveness, making it feel tighter and more connected to the road.

Brakes: Stopping Power You Can Trust

With increased power comes the need for improved braking performance. Upgrading the brakes is crucial for ensuring that you can safely and effectively control the car, especially during spirited driving or track days. Improved braking systems are vital for maintaining control and safety, particularly when pushing the car to its limits. Upgrading the brakes involves more than just swapping out pads; it's about ensuring that the entire system works efficiently to provide consistent and reliable stopping power. High-performance brake systems are designed to withstand the extreme temperatures and stresses of aggressive driving, providing fade-free performance and enhanced pedal feel.

Brake Pads and Rotors: The First Line of Defense

A simple and effective upgrade is to replace the factory brake pads and rotors with high-performance alternatives. Performance brake pads, such as those from Hawk or EBC, offer increased friction and improved heat resistance, providing better stopping power and reduced brake fade. Upgrading to slotted or drilled rotors can further improve braking performance by dissipating heat more effectively and reducing the risk of glazing. These rotors are designed to vent hot gases and debris away from the braking surface, maintaining consistent performance even under demanding conditions. It’s important to choose brake pads and rotors that are compatible with your driving style and intended use, whether it's for street driving or track days.
