The Mitsubishi Lancer Evolution X, known for its impressive performance and handling, can benefit greatly from brake upgrades. Stock brakes are adequate for daily driving, but enthusiasts often seek enhanced stopping power, especially for track days or spirited driving. This article explores the journey of upgrading from stock brakes to 300mm big brakes, detailing the benefits and considerations involved.
Understanding the Stock Brake System
The stock brake system on the Evo X features ventilated disc brakes with a reasonable performance level for most driving conditions. However, for those pushing the limits, these brakes can fade under heavy use. Understanding the components of the stock system is essential for appreciating the upgrades.
- Front Brakes: 320mm ventilated discs with dual-piston calipers.
- Rear Brakes: 300mm ventilated discs with single-piston calipers.
- Brake Pads: Standard pads designed for everyday driving.
Why Upgrade to 300mm Big Brakes?
Upgrading to 300mm big brakes offers several advantages, particularly for performance-oriented drivers. The larger brake components provide increased surface area for better heat dissipation and improved braking performance.
- Improved Stopping Power: Larger rotors and calipers provide more braking force.
- Heat Management: Bigger brakes dissipate heat more effectively, reducing fade.
- Better Modulation: Enhanced feel and control during braking.
Components of a 300mm Big Brake Upgrade
When considering a big brake upgrade, several key components need to be addressed to ensure optimal performance and compatibility with the Evo X.
- Rotors: Upgraded 300mm slotted or drilled rotors for better performance.
- Calipers: High-performance calipers that can accommodate larger rotors.
- Brake Pads: Performance-oriented pads designed for track and street use.
- Brake Lines: Stainless steel braided lines for improved pedal feel.
- Fluid: High-temperature brake fluid to withstand the rigors of performance driving.
Installation Process
Installing a 300mm big brake kit requires mechanical knowledge and the right tools. Here’s a general overview of the installation process:
- Remove the wheels to access the brake components.
- Disconnect the brake lines and remove the stock calipers.
- Remove the stock rotors and install the new 300mm rotors.
- Attach the new calipers and connect the brake lines.
- Install performance brake pads and ensure proper alignment.
- Bleed the brake system to remove air from the lines.
- Reinstall the wheels and perform a test drive to ensure functionality.
Choosing the Right Components
Not all big brake kits are created equal. When selecting components for your Evo X, consider the following:
- Brand Reputation: Choose reputable brands known for quality and performance.
- Compatibility: Ensure parts are designed specifically for the Evo X.
- Intended Use: Select components based on whether you prioritize street performance, track use, or a combination of both.
Cost Considerations
Upgrading to a 300mm big brake system can be a significant investment. Costs will vary based on components and labor. Here’s a breakdown of potential expenses:
- Brake Kit: $1,000 – $3,000 depending on brand and features.
- Installation Labor: $200 – $500 if using a professional mechanic.
- Additional Parts: Budget for new brake fluid and lines, around $100 – $300.
Performance Benefits After Upgrading
Once the upgrade is complete, drivers will notice significant improvements in braking performance. Key benefits include:
- Shorter Stopping Distances: Enhanced braking power leads to quicker stops.
- Consistent Performance: Reduced brake fade during prolonged use.
- Increased Confidence: Improved modulation and feel during hard braking.
Conclusion
Upgrading from stock brakes to 300mm big brakes on the Evo X is a valuable enhancement for performance enthusiasts. With improved stopping power, better heat management, and increased confidence, this upgrade can transform the driving experience. Always consider your driving habits and choose components that align with your performance goals for the best results.
