Transmission⁚
- Short-throw shifter⁚ This modification reduces the throw distance between gears, providing quicker and more precise shifts․
- Limited-slip differential (LSD)⁚ An LSD helps improve traction and handling by distributing power more evenly to the wheels, particularly when cornering or accelerating․
- Clutch⁚ Upgrading to a high-performance clutch with a higher clamping force allows for smoother and more controlled power delivery, especially under heavy acceleration․
- Gearbox⁚ Replacing the stock gearbox with a close-ratio unit can provide quicker acceleration and better performance in a wider range of RPMs․
Driveshaft and Axles⁚
- Driveshaft⁚ Upgrading to a stronger driveshaft can handle the increased power output and torque generated by engine modifications․
- Axles⁚ Replacing the stock axles with stronger units can prevent failures under high loads and demanding driving conditions․
Brakes⁚
- Larger rotors⁚ Upgrading to larger brake rotors increases braking surface area, providing better stopping power and heat dissipation․
- High-performance brake pads⁚ Replacing stock pads with higher-friction pads improves braking performance and provides better fade resistance under heavy braking․
- Brake lines⁚ Upgrading to braided stainless steel brake lines reduces brake pedal flex and provides a more responsive braking experience․
Wheels and Tires⁚
- Lightweight wheels⁚ Lighter wheels reduce unsprung weight, improving acceleration, handling, and braking performance․
- Wider wheels and tires⁚ Wider wheels and tires improve grip and handling, allowing for more aggressive driving․
- High-performance tires⁚ Tires designed for track use or high-performance driving offer better grip, handling, and durability․
