RSH 3 is an organic compound developed for historic-car sprint use and serves as the more assertive option within the historic range. It combines strong initial bite with broad usability, excellent modulation, and clean release characteristics, giving it a more aggressive and performance-oriented character than RSH 42 while remaining controlled and manageable. Its application range includes rally, GT and touring cars in circuit racing, as well as club racing with historic cars. With its combination of a high friction coefficient, firm pedal feel across temperatures, fade resistance up to 800 C, and low thermal conductivity, RSH 3 delivers a strong, consistent, and confidence-inspiring braking response for demanding historic motorsport conditions.
