Halo GT is the most technically advanced DOT 4 racing brake fluid, designed for racers, trackday drivers and serious enthusiasts who want racing performance in a road-compliant DOT 4 fluid. Built on the proven chemistry of the flagship Halo P1 — developed for the highest demands of motorsport — GT brings that same performance DNA to a wider range of drivers, while being fully DOT 4 compliant and optimised for the latest racing ABS systems.
With an ultra-low kinematic viscosity of just 1350 cSt at -40°C, Halo GT allows the brake system to respond faster, improving communication between driver and car — faster pressure build-up, cleaner release and greater control at the limit. Featuring Fade Resistant Technology™, it delivers thermal stability and a consistent pedal feel under the most demanding conditions, giving you the confidence to brake later, release faster and accelerate earlier, lap after lap.
Halo is backed by Orthene's 50+ years of brake fluid innovation, with an estimated 80% of the world's racing brake fluid produced by Orthene. Every bottle is developed, manufactured and quality controlled in the UK.
