BCB Upgraded Brake Booster (GR Corolla)

Enhanced Brake Booster – Track-Tested by 555 Engineering

Developed in collaboration with BCB and rigorously tested on our own 555 Engineering Development GR Corolla, this upgraded brake booster is designed for serious drivers who demand precision at the limit.

Built with feedback from real-world track use, it delivers improved pedal modulation for trail braking, left-foot braking, and high-performance compound pads. Many track-focused GRC drivers have reported that the factory booster can feel too binary—engaging ABS too quickly and making brake control difficult under pressure.

This performance brake booster solves that issue, giving you progressive pedal feel and greater braking finesse when it matters most. Whether you're diving into a corner or scrubbing speed at the edge of grip, this is the confidence upgrade your braking system needs.
