Pads for AP Racing CP2399 (LD20).
Fits: AP CP2399.
Same shape. Very different pads.
Every compound below bolts into the same AP Racing CP2399 (LD20) 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. Manufacturers test on their own equipment, so friction numbers are best compared within a brand rather than across brands. Not sure which suits your AP Racing CP2399 (LD20) setup? Ask BuildBot or email us with your car, class and typical session length.
