140-15304 WILWOOD

Review WILWOOD

The Wilwood 140-15304 Big Brake Kit is an exceptional upgrade for vehicles in need of superior braking performance. This kit is specifically designed for front applications on certain Subaru models, including Impreza WRX STI, Forester XT, and Outback XT. The kit comes with six components: two-piece slotted and drilled rotors, four piston calipers, stainless steel brake lines, and mounting hardware.

The rotors, measuring 13.6 inches in diameter and 1.2 inches thick, offer increased stopping power and improved thermal capacity. The two-piece design enables easy and cost-effective replacement of the friction material without having to replace the entire rotor. The drilled and slotted rotors provide superior bite and better resistance to brake fade by allowing gases to escape and water to dissipate.

The four-piston calipers are designed to provide consistent, even clamping force on the pads and rotors, ensuring optimal braking performance under various conditions. The calipers are finished in a durable black powder coat to protect against the elements and provide a sleek appearance.

The stainless steel brake lines offer superior resistance to corrosion and flex compared to the standard rubber lines. The rigid lines ensure a consistent brake pedal feel and improve braking performance by minimizing the amount of brake fluid that can be forced out under high pressure.

The mounting hardware included in the kit is designed to provide a secure and precise fitment. The hardware is made of high-strength steel and is finished in zinc plating to protect against corrosion.

The Wilwood 140-15304 Big Brake Kit is designed, engineered, and manufactured in the USA, ensuring the highest quality and performance. This kit is an excellent choice for those seeking improved braking performance and confidence-inspiring stopping power.

The Wilwood 140-15304 brake kit is a popular aftermarket option for upgrading the braking system in various applications, including certain Ford Mustangs and other performance vehicles. Here are some potential pros and cons to consider before making a purchase:

1. Improved Braking Performance: Wilwood brake kits are known for their superior braking power and modulation. This can lead to improved stopping distance and better control, especially during high-performance driving.

2. Customizable: This particular kit offers several options, including various rotor sizes, caliper finishes, and brake pad compounds. This allows buyers to tailor the kit to their specific needs and preferences.

3. Durability: Wilwood brake components are made from high-quality materials and are designed to withstand the rigors of high-performance driving. This can lead to longer component life and reduced maintenance requirements.

4. Improved Pedal Feel: The upgraded braking components can provide a more direct and responsive pedal feel, making it easier for drivers to modulate their braking input.

1. Cost: Wilwood brake kits can be more expensive than OEM or aftermarket alternatives. This may be a deterrent for some buyers.

2. Installation Complexity: Installing a Wilwood brake kit can be a more complex process than installing OEM components. This may require additional time, tools, and expertise.

3. Compatibility: While the 140-15304 kit is designed for specific applications, there may be compatibility issues or fitment concerns for certain vehicles. It is important to ensure that the kit is compatible with your specific make and model before making a purchase.

In conclusion, the Wilwood 140-15304 brake kit offers significant upgrades in terms of braking performance, customization options, and durability. However, it comes with a higher price tag and increased installation complexity. If you are looking to significantly improve your vehicle's braking performance and are willing to invest time and money into the upgrade, then this kit may be a worthwhile investment. On the other hand, if you are looking for a more affordable or easier solution, you may want to consider alternative brake kit options.
