The Subaru BRZ is known for its balance, lightweight chassis and driver-focused character. However, when driving becomes more dynamic especially on mountain roads or during spirited street use, the limitations of the stock braking system quickly become noticeable.
That’s exactly why one of our customers from Spain decided to upgrade his Subaru BRZ II Gen with a complete K-SYSTEM Big Brake Kit 326mm, featuring Brembo 4-piston calipers and custom-engineered adapters.
Why upgrade the brakes on a Subaru BRZ?
While the BRZ offers excellent handling from the factory, the original braking system is not designed for repeated hard braking or higher thermal loads. Common issues include:
- reduced braking consistency,
- longer stopping distances,
- brake fade during aggressive driving.
A Big Brake Kit addresses these problems directly by improving braking force, heat resistance and pedal modulation.
The setup – Subaru BRZ BBK 326mm by K-SYSTEM
For this build, the customer chose a full front axle Big Brake Kit, including both calipers and adapters, ensuring perfect compatibility and performance.
Specification:
- Brembo 4-piston calipers (Megane 3 RS type)
- Custom K-SYSTEM adapters, engineered specifically for the Subaru BRZ
- Plug & Play installation
- Compatible with OEM or braided brake lines
Every component in the kit is selected and designed to work together as a complete system.

Custom adapters
The key of this conversion lies in the custom K-SYSTEM caliper adapters. Designed specifically for the BRZ platform, they ensure:
- correct caliper positioning relative to the disc,
- proper brake pad contact,
- optimal rigidity under load,
- true Plug & Play installation without modifications to the upright.
This is what separates a properly engineered Big Brake Kit from random component combinations.
Real-world results
After installation, the braking system delivers:
- noticeably stronger initial bite,
- improved pedal feel and modulation,
- consistent performance under repeated braking,
- increased confidence during dynamic driving.
This setup works equally well for street driving and occasional track use, making it a balanced and reliable upgrade for the Subaru BRZ.
