The compound
WinmaX W4.
A step up from W3 for sprint and entry-level motorsport, with a 50°C floor that keeps it usable on a cold first lap and a 700°C ceiling that survives a short race. It sits in the gap between the versatile road-and-track W3 and the full circuit W5.
Operating range50–700°C
Friction µ0.37–0.40

These are the compounds we stock for the Wilwood Dynalite Single / Dynapro Single 6812 whose published friction and operating temperature come closest to WinmaX W4. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
