    Operating range not published

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. Manufacturers test on their own equipment, so friction numbers are best compared within a brand rather than across brands. Not sure which suits your Brembo GT 6-pot B24 (RD54) setup?
