The compound
WinmaX W3.
A semi-metallic, low-steel compound and the most widely used pad in the W-series. WinmaX describe it as their most versatile: usable on the road, and still consistent through a sprint or a trackday session. It works from ambient with a 650°C ceiling, which is what makes it the safe default for a car that drives to the circuit and races the same day.
Operating range0–650°C
Friction µ0.34–0.37
Cross-brand equivalents
Run something similar.
These are the compounds we stock for the AP Racing 6-pot RD54 (with tab) whose published friction and operating temperature come closest to WinmaX W3. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
Project Mu H21
Partial match200–850°C
Circuit and endurance racing. Project Mu rate it as kind to the rotor with long pad life.
Matched on published operating temperature only — one of the two brands doesn’t publish a friction figure, so this is a weaker comparison.
