- Sway Bars: Upgrading to stiffer sway bars can reduce body roll, enhancing cornering stability.
- Tires: High-performance tires provide better grip and handling on the track. Look for options that suit your driving style and track conditions.
- Brake Upgrades: Upgrading to larger rotors and performance brake pads can improve braking performance and reduce fade during track sessions.
Alignment and Setup
A proper alignment is vital for maximizing handling. Consider the following:
- Camber Adjustment: Adjusting camber angles can improve tire contact with the road during cornering.
- Toe Settings: Fine-tuning toe settings can enhance straight-line stability and cornering response.
Reliability Upgrades
When pushing your Civic Si to its limits on the track, reliability becomes paramount. Here are some upgrades to consider:
- Oil Cooler: An aftermarket oil cooler can help maintain optimal oil temperatures during high-performance driving.
- Upgraded Radiator: A larger radiator can improve cooling efficiency, preventing overheating during extended track sessions.
- High-Performance Fluids: Using synthetic oils and high-performance brake fluid can enhance reliability and performance.
- Regular Maintenance: Keeping up with regular maintenance, such as oil changes and inspections, is crucial for reliability.
