Product Details
This Brembo big brake kit for your WRX STi includes everything you need to significantly upgrade your front braking system. You get a pair of 6-piston forged aluminum calipers, a pair of 2-piece rotors measuring 380x35mm with 53mm offset, and T3 black hats. This is a comprehensive package designed for serious performance driving, offering a substantial improvement over stock components.
The calipers are forged from aluminum, which is strong yet lightweight, helping to reduce unsprung weight. This contributes to better handling and suspension response. The 2-piece rotor design allows for better thermal management. The rotor itself is a 380x35mm disc, providing a large surface area for heat dissipation and consistent braking force. The T3 black hats are part of this 2-piece rotor assembly, designed to work seamlessly with the rotors and calipers for optimal performance and durability under demanding conditions. This kit is built for track use and spirited driving where consistent, powerful braking is essential.
When installing a big brake kit like this, it's important to follow the manufacturer's instructions carefully. Ensure you have the correct tools and consider having a professional mechanic perform the installation if you're not experienced with brake system work. Proper bedding-in of the new pads and rotors is also crucial for achieving optimal performance and longevity from this high-performance braking system.
