This is TrackTheory’s recommendation for the Wilwood Dynapro 7812 / 7816, not manufacturer advice — a starting point based on the published figures below and what we stock, not a survey of what other competitors run. Car weight, driving style and how long your sessions are all move the answer, so tell us yours and we’ll give you a straighter one.
Same shape. Very different pads.
Every compound below bolts into the same Wilwood Dynapro 7812 / 7816 caliper. What separates them is operating temperature and friction — a sprint pad that needs heat in it will feel wooden on a cold first lap, and a road-biased pad will fade before the end of a long race. Figures are the manufacturers’ own published data.

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 Dynapro 7812 / 7816 setup? Ask BuildBot or email us with your car, class and typical session length.
