With a variety of high-quality options available, we break down some of the best kits on the market to help you choose the perfect upgrade for your WRX.
1. Endless MONO6 SPORTS TA Front Brake Kit – $5,170
For WRX enthusiasts who appreciate Japanese racing technology, the Endless MONO6 SPORTS TA is a high-rigidity forged monoblock 6-piston caliper system, designed for street and track use. Built with advanced engineering, this kit delivers uncompromising performance without unnecessary weight.
What’s Included:

This kit is made to order in Japan with a 30-60 day lead time, making it a premium option for serious drivers who demand high-quality materials and precision engineering.
2. Brembo Race Technologies GTS Big Brake Kit (Front Only) – $4,595
For EyeSight and Electronic Parking Brake (EPB) equipped WRX models, the Subaru WRX GTS BBK is a direct bolt-on upgrade designed specifically for the VB chassis.
Key Features:
✔ 6-Piston Cast Monobloc Calipers
✔ 350mm (13.8”) Two-Piece Floating Rotors
✔ Brembo FM1000 High-Performance Pads
✔ Brembo Stainless Steel Braided Brake Lines
As a pre-assembled kit, installation is straightforward, making it a great choice for WRX owners looking for a performance-driven upgrade without extensive modifications. Pre-orders are required, so verifying fitment before purchasing is recommended.
3. Rotora Big Brake Kit (6-Piston Front, 4-Piston Rear) – $5,559
The Rotora Street Challenge Brake System is a balanced street and track-ready solution that enhances pedal feel, braking power, and overall performance. Designed to work seamlessly with the OEM master cylinder, this kit delivers shorter stopping distances and improved weight transfer during braking.
Key Features:
✔ 6-Piston Front / 4-Piston Rear Forged Aluminum Calipers
✔ 355mm x 32mm Front & 350mm x 29mm Rear Two-Piece Slotted Rotors
✔ H2 High-Ceramic Pads (Street & Light Track Use)
✔ DOT-Compliant Stainless Steel Braided Brake Lines
Since Rotora BBKs are made to order, expect a 60-90 day lead time before delivery. If you’re running OEM wheels, a 2mm spacer may be required for proper clearance up front.
4. Subaru STI 6-Piston/2-Piston Brembo Brake Kit – $4,199
For those seeking an OEM-based upgrade, this kit brings the 6-piston front, 2-piston rear Brembo brakes from the 2018-2021 WRX STI to the 2022+ WRX. However, because of the platform change, these Brembos don’t bolt on directly—this kit solves that problem with custom two-piece front rotors for a perfect factory-like fit.
What’s Included:
✔ Genuine Subaru Brembo Calipers (6-Piston Front, 2-Piston Rear)
✔ Custom Mach V Slotted Two-Piece Front Rotors (13.4”)
✔ KNS/DBA Rear Rotors (12.8”)
✔ OEM Subaru Brake Pads & Hardware
This bolt-on factory solution is ideal for WRX owners looking for OEM reliability with improved performance. However, keep in mind that OEM wheels require a 20mm spacer for clearance, and the rear kit won’t fit CVT models with electronic parking brakes.
5. Essex AP Radi-CAL Front Competition Brake Kit – $5,699
For serious track drivers, the Essex AP Racing Radi-CAL BBK is one of the best weight-saving, high-performance brake kits available. Engineered for maximum heat dissipation and endurance, this kit ensures consistent braking under extreme conditions.
