Prospeed RS683 is extreme performance brake fluid for extreme race cars!

The ONLY racing / high performance brake fluid developed and manufactured in the USA, Prospeed RS683™ extreme performance brake fluid is a new name to the market and is already one of the highest performance brake fluids available.
Race-proven in the highest forms of motorsports, Prospeed GS610™ was used by professional racing teams like Andretti-Green Racing (AGR) with drivers Bryan Herta, Dario Franchitti, Tony Kanaan and Marco Andretti as well as other race teams in the ALMS, Grand AM, World Challenge series and others. This formula won many significant races including the 2005 Indianapolis 500!... But Prospeed felt they could do better.
With a great brake fluid history, they wanted to build upon this success of GS610. Continuing research and development, looking to develop another new brake fluid with an even higher performance threshold, RS683 has been created.

Prospeed RS68™ blended with CompressionFree™ brake fluid blending technology and a boiling point of 683.2 ° F (361.8 ° C) is amongst the highest performance racing brake fluid available at any price...
RS683 was specifically developed to address the extreme environment of racing sports cars prototypes and stock cars, as well as all other driving environments where drivers demand the ultimate in braking control only offered by a brake fluid with virtually non-existent compressibility, high temperature stability and consistent extreme performance.

RS683 also has a a very high wet boiling point, something uncommon with many high performance DOT 5.1 fluids. It's low hydroscopic nature (low tendency to absorb water from surrounding air) provides heightened resistance to corrosion and superior brake performance over a longer life cycle as well.
