What we’d fit.
The Sumitomo four-pot is a road caliper doing a track job. A compound that works from cold gets more out of it than one that needs heat the caliper struggles to hold.
WinmaX W3
WinmaX call this their most versatile pad: sportive street through to sprint racing. It is the W-series compound we stock most of.

This is TrackTheory’s recommendation for the Sumitomo 4-pot — WRX / 300ZX / Skyline Turbo, 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 Sumitomo 4-pot — WRX / 300ZX / Skyline Turbo 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.
