AP Racing's established range of racing brake and clutch fluids have been refreshed and re-branded to embrace the Radi-CAL™ philosophy. Following last years successful launch of Radi-CAL™ R4 racing brake fluid, AP Racing has chosen to re-align its full range of fluids by renaming PRF660, 600, 551 and Formula Dot 5.1, changing the bottle and caps.
IMPORTANT NOTE: NO alterations have been made to the actual brake and clutch fluids themselves.
AP Racing brake fluid has been developed specifically for use under the arduous conditions encountered at the highest levels of motorsport.
Radi-CAL™ R4 has been designed to perform better than any other product at the extremes of heavy duty braking performance in the top levels of racing. With the highest dry boiling point of any racing brake fluid currently available at 340°C, R4 stands alone.
