Review STOPTECH

The STOPTECH Sport Brake Kit 612.42039 is an exceptional upgrade for your vehicle's braking system. Designed for select applications of Subaru WRX and STI models, this kit is engineered to deliver improved braking performance and response, ensuring a safer and more enjoyable driving experience.

The heart of this brake kit is the ST40 328mm front and 286mm rear drilled and slotted rotors. These rotors, crafted from high-carbon cast iron, provide excellent thermal capacity and resistance to warping. Drilled holes allow for efficient cooling and weight reduction, while the slots help dissipate water and gas during heavy braking, reducing the risk of brake fade.

The kit also includes STOPTECH's ST-40 4-piston fixed calipers, which offer increased clamping force and better brake pedal feel compared to the stock calipers. These calipers are painted in a durable red finish, adding a striking visual appeal to your vehicle.

The kit is completed with STOPTECH Street Performance brake pads, which provide strong initial bite and consistent, predictable performance throughout the pad life. These pads are suitable for daily driving and occasional track use.

The STOPTECH Sport Brake Kit 612.42039 is designed to work seamlessly with your vehicle's factory master cylinder and power brake booster, making for a straightforward installation process. The included brake lines are made from high-quality stainless steel, ensuring durability and resistance to corrosion.

In summary, the STOPTECH Sport Brake Kit 612.42039 is an excellent investment for those seeking enhanced braking performance and improved driving confidence. With its high-performance rotors, upgraded calipers, and Street Performance brake pads, this kit is the perfect solution for upgrading your Subaru WRX or STI's braking system.

The StopTech Sport Brake Kit 612.42039 is a popular aftermarket brake upgrade for various Volkswagen and Audi models. This kit is known for its performance improvements, but like any automotive upgrade, it comes with its pros and cons.

1. Improved Braking Performance: The main advantage of this brake kit is the enhanced braking power it provides. The larger brake rotors and high-performance pads offer better stopping power, especially during aggressive driving or high-speed situations.

2. Enhanced Pedal Feel: The upgraded brake kit provides a more responsive and firmer brake pedal feel, allowing for more precise and effective braking.

3. Durability: The StopTech Sport Brake Kit is built to last, with high-quality materials and components that can withstand the demands of high-performance driving.

4. Safety: The improved braking performance can significantly enhance the safety of your vehicle, allowing you to react more quickly and effectively in emergency situations.

1. Cost: The StopTech Sport Brake Kit is a premium upgrade, and the cost can be a significant investment. The price tag may be a deterrent for some buyers.

2. Installation Complexity: Installing the brake kit can be a complex process, requiring specialized tools and knowledge. It may be best to have the installation done by a professional to ensure proper installation and optimal performance.

3. Noise: Some users have reported increased brake noise after installing the kit. While this is a common issue with high-performance brake systems, it can be a concern for some buyers.

4. Potential for Vibration: High-performance brake kits can sometimes result in vibration or pulsation during braking. This can be caused by various factors, including rotor size, pad material, or caliper design.

The StopTech Sport Brake Kit 612.42039 offers significant performance improvements for Volkswagen and Audi models. The enhanced braking power, responsive pedal feel, and durability make it an attractive option for those seeking a high-performance driving experience. However, the cost, installation complexity, and potential for increased noise and vibration are important considerations. Ultimately, the decision to purchase this brake kit depends on your budget, driving style, and priorities.

If you are a serious performance enthusiast and have the budget for it, the StopTech Sport Brake Kit 612.42039 is an excellent choice for enhancing the braking performance of your Volkswagen or Audi. For those on a tighter budget or with less aggressive driving styles, a more affordable brake upgrade or stock replacement may be a more suitable option. It is recommended to consult with a professional mechanic or brake specialist to help determine the best brake solution for your specific needs and vehicle.
