Below are the official compound descriptions from Ferodo Racing Italy. Please note that the primary value of these graphs is to compare the Ferodo Racing compounds against each other. Comparing the absolute numbers below to published numbers from other manufacturers is of little value, and would be akin to comparing engine dyno graphs from different dyno types (Dynojet vs. Mustang Dyno, etc.). Again, if you’re unsure which compound is right for your needs, please contact us for a recommendation.
