The Mazda RX-7 is a legendary sports car known for its lightweight design and rotary engine. When pushing the limits to achieve over 400 horsepower, upgrading the suspension and brakes becomes essential for maintaining high-speed stability and performance. This article will explore the best practices and components for enhancing your RX-7’s handling and braking capabilities.
Understanding the Importance of Suspension and Brakes
With an increase in horsepower, the demands on the suspension and braking systems rise significantly. Proper upgrades ensure that the vehicle remains controllable and safe at high speeds. Key benefits of upgrading include:
- Improved handling and cornering stability
- Enhanced braking performance
- Better tire contact and grip
- Increased driver confidence
Suspension Upgrades
Upgrading the suspension is crucial for handling the increased power and speed. Here are the main components to consider:
Coilovers
Coilover kits provide adjustable ride height and damping settings, allowing you to fine-tune your RX-7 for various driving conditions. Look for options that offer:
- Height adjustability
- Rebound and compression adjustments
- Durable materials for longevity
Anti-Roll Bars
Upgrading anti-roll bars helps reduce body roll during cornering, enhancing stability. Consider:
- Stiffer bars for improved handling
- Adjustable options for fine-tuning
- High-quality bushings for better performance
Strut Braces
Strut braces enhance chassis rigidity, which improves handling response. Key features to look for include:
- Lightweight materials like aluminum or carbon fiber
- Easy installation
- Compatibility with other suspension components
Brake System Upgrades
Braking performance is vital when handling high speeds. Upgrading the brake system ensures that you can stop effectively and safely. Consider the following components:
Brake Pads
High-performance brake pads offer improved stopping power and fade resistance. Look for pads that provide:
- High friction coefficients
- Better heat dissipation
- Minimal dust production
Brake Rotors
Upgrading to larger or slotted/drilled rotors enhances cooling and braking efficiency. Consider these features:
- Increased surface area for better heat management
- Lightweight materials to reduce unsprung weight
- Corrosion-resistant coatings
Brake Calipers
High-performance calipers provide better clamping force and heat dissipation. When selecting calipers, look for:
- Multi-piston designs for increased braking power
- Lightweight construction
- Compatibility with upgraded rotors
Choosing the Right Tires
The right tires play a crucial role in maximizing the performance of your upgraded suspension and brakes. Opt for:
- High-performance summer tires for optimal grip
- Proper tire sizing for your suspension setup
- Regular maintenance and pressure checks
Final Thoughts
Upgrading the suspension and brakes of your Mazda RX-7 is essential for harnessing the full potential of a 400+ horsepower engine. By investing in high-quality components and making strategic upgrades, you can ensure that your vehicle remains stable, responsive, and safe at high speeds. Remember to consider your driving style and intended use when selecting parts to achieve the best results.
