The 2019 Subaru WRX Limited, while a thrilling ride, can benefit significantly from a brake and rotor upgrade. Stock brakes, while adequate for daily driving, often struggle under hard braking, especially during spirited driving or track days. This guide delves into the reasons for upgrading, explores various options, and helps you choose the best components for your needs and budget.
Why Upgrade Your Brakes and Rotors?
Several factors make a brake and rotor upgrade worthwhile for your 2019 WRX Limited:
-
Improved Stopping Power: The stock brakes can fade under sustained high-performance driving. Upgraded brakes provide superior stopping power, even at high temperatures, resulting in shorter stopping distances and enhanced safety.
-
Increased Fade Resistance: Upgraded brake pads and rotors are typically made from materials that resist heat build-up, reducing brake fade and ensuring consistent performance, crucial for track days or aggressive driving.
-
Enhanced Pedal Feel: Many aftermarket brake systems offer a firmer, more responsive pedal feel, leading to improved driver control and confidence.
-
Upgraded Aesthetics: Let's be honest, larger brakes and calipers often look more aggressive and enhance the visual appeal of your WRX.
Choosing Your Upgrade Path: Components and Considerations
The key components to consider for your brake upgrade are:
1. Brake Pads:
Several pad compounds cater to different driving styles:
-
Street Pads: Offer good stopping power for daily driving with minimal noise and dust. Look for pads with good initial bite and consistent performance.
-
Performance Street Pads: A balance between street manners and track capability, offering improved stopping power and fade resistance compared to street pads.
-
Track Pads: Designed for high-performance driving and track use. They provide exceptional stopping power and fade resistance but often generate more noise and dust and may have a shorter lifespan.
2. Rotors:
Rotor material significantly impacts performance and lifespan:
-
OEM-Style Rotors: Directly replace the stock rotors and offer a reliable and cost-effective option.
-
Cross-Drilled Rotors: Holes are drilled into the rotor to help dissipate heat and reduce brake fade. However, drilling can weaken the rotor if not done correctly.
-
Slotted Rotors: Slots cut into the rotor surface improve brake pad bite and help clear away dust and debris. They also aid in heat dissipation.
-
Drilled and Slotted Rotors: Combine the benefits of both drilling and slotting for optimal performance.
-
Two-Piece Rotors: These high-performance rotors consist of a hat and a rotor ring, offering improved heat dissipation and reduced weight.
3. Calipers:
Upgrading your calipers often requires a complete brake kit. Consider:
-
Larger Calipers: Larger calipers provide increased clamping force, leading to improved stopping power. This often involves upgrading to a bigger rotor as well. This is generally a more involved installation.
-
Performance Calipers: These calipers are designed for high-performance applications and provide superior stopping power and fade resistance.
Installation: DIY or Professional?
Installing a brake upgrade is a complex task requiring mechanical skills and specialized tools. If you lack experience, it's strongly recommended to have a professional mechanic perform the installation. Incorrect installation can compromise safety and void warranties.
Budget and Research:
Before you buy, research various brands and read reviews. Set a budget and prioritize components based on your driving style and needs. Remember that a comprehensive upgrade (pads, rotors, and potentially calipers) represents a significant investment.
Conclusion:
Upgrading your 2019 Subaru WRX Limited's brakes and rotors can significantly enhance your driving experience, providing improved stopping power, fade resistance, and a more responsive pedal feel. Carefully consider your driving style, budget, and the available options to select the components that best suit your needs. Remember always prioritize safety and professional installation where necessary.
