Figures are the manufacturers’ own published data for each compound. Where a brand doesn’t publish a figure we say so rather than estimate it. From cold is our reading of each manufacturer’s published minimum operating temperature, not a separate rating they publish. Wilwood publish friction as graphs rather than as specifications, so those figures are read off the curve and are indicative rather than exact. Manufacturers test on their own equipment, so friction numbers are best compared within a brand rather than across brands. Not sure which suits your Wilwood Powerlite 7912 setup?
