With all the performance traits of our Carbon Reinforced line, GS4 delivers a slightly lower friction coefficient range from 0.45 – 0.49, with a solid initial bite and good modulation characteristics. GS4 achieves remarkably stable stopping power in the low to middle temperature range – ideal for asphalt, rally and dirt-track racing.

Quality engineering, manufacturing, friction components and attachment mechanisms make GS4 a preferred choice amongst professional race teams. As with all advanced racing applications, care must be taken to properly test, determine and select the correct friction for your vehicle and racing style.

Good wear rates and rotor-friendly operation in its temperature range makes GS4 an ideal choice for track and drag race activities. Remember that friction of this caliber places high performance demand on your brake system and will cause more wear on stock components such as rotors and calipers than conventional street performance compounds.
