Years of testing across America’s most prestigious races has resulted in a well-rounded compound that offers ideal modulation and pedal communication, with ground breaking friction stability across a thermal range as high as 1,600 Deg F. This consistency of performance, hour after hour, makes it ideal for not only endurance racing, but HPDE, track days, time trials and even sprint racing.\u003c\/p\u003e\u003ch2\u003eHawk Performance ER-1 Race Compound Characteristics:\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSuperior Rotor and Pad Wear.\u003c\/li\u003e\n\u003cli\u003eConsistent Medium to High Friction.\u003c\/li\u003e\n\u003cli\u003eIdeal for light-to-medium weight vehicles in HPDE, Track Day events, Time Trials, or Endurance Racing.\u003c\/li\u003e\n\u003cli\u003eHigher coefficient of friction than competing endurance pads, with matched or improved lifespan.\u003c\/li\u003e\n\u003cli\u003eMedium to High Torque\u003c\/li\u003e\n\u003cli\u003e400-1600 Deg F Operating Temperature Range\u003c\/li\u003e\n\u003cli\u003e700-1100 Deg F Optimal Temperature Range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHawk Race Compound Chart\u003c\/h2\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0047\/8865\/0055\/files\/Hawk_ER-1_Graph.jpg?v=1641250490\" alt=\"Hawk Performance ER-1 Endurance Race Compound\"\u003e\u003ch3\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0047\/8865\/0055\/files\/prop65_10pt.png?v=1611080686\" alt=\"Warning Prop 65\"\u003e WARNING\u003c\/h3\u003e\u003cp\u003eThis product can expose you to Silica, crystalline (airborne particles of respirable size), which is known to the State of California to cause cancer.
