Project Mu G-Four 335 Brake Fluid: High-Performance DOT 4 Solution for Track and Street Braking
The Project Mu G-Four 335 Brake Fluid, a 100% synthetic glycol-based DOT 4 formula engineered for demanding drivers who require reliable stopping power in high-heat scenarios. With a dry boiling point of 335°C (635°F) and a wet boiling point of 221°C (430°F), this fluid maintains consistent pedal feel and prevents vapor lock during extended track sessions or spirited road drives.
