Q: Should I add brake ducts or high-temp fluid for track use?

For spirited track driving we strongly recommend high-temperature racing brake fluid, such as Motul RBF 660 or Endless RF-650, along with a proper bed-in and our brake cooling duct solution. At this weight and power, fluid management and temperature control are critical to avoid a mushy pedal. Stage 2 gives you huge capacity, but pairing it with the carbon fiber brake cooling duct kit is how you keep it consistent deep into a session.
