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.
