Pads for Mazda RX7 FC / FD.
Fits: RX7 FC front, RX7 FD front, RX7 FC/FD rear.
What we’d fit.
More weight and more speed than an MX5, so the circuit compound is the sensible floor rather than the ceiling.
WinmaX W5
WinmaX’s standard circuit model, and the default club racing and rally choice in the range.

The standout for sprints and hillclimbs: close to 0.5 friction from a 50°C floor, so it bites on lap one. WinmaX call it their best rally pad.

This is TrackTheory’s recommendation for the Mazda RX7 FC / FD, 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 Mazda RX7 FC / FD 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 Mazda RX7 FC / FD setup? Ask BuildBot or email us with your car, class and typical session length.
