Wilwood's new XR Race-Only* brake fluid is the same extreme high-temperature fluid used in Formula 1, World Rally Championship, FIA World Endurance, and Moto GP. Laboratory testing indicates XR Race-Only fluid has a dry boiling point of 645° F thanks to a proprietary blend of high-performance polymer electrolytes and borate esters. This polyglycol-ether-based brake fluid combines the lowest compressibility, lowest moisture affinity, and highest resistance to aeration of any brake fluid available. XR Race-Only Brake Fluid is formulated to deliver the absolute best, most consistent pedal feel, start to finish, even in the most adverse racing conditions. For racers, the wet boiling point is irrelevant; only a high dry boiling specification matters. If the brakes are bled and filled with fresh fluid before events as part of your pre-race ritual, you will never absorb enough moisture to lower the dry boiling point. The premium metal 16.9 ounce can with airtight safety seal ensures fresh, clean fluid upon opening. (* For off-highway use only. Not DOT approved.) Download Whitepaper
