Semi-metallic compound built for Excel racing, with real temperature range to match.
“The bite is there from the first stop, and it stays there.”
Channel: marketing:WinmaX W4 Performance Trackday B Draft: Budget pads fade when temperatures climb through a race session — the W4 compound is engineered to stay consistent up to 700°C, which is where Excel racing actually lives. The semi-metallic formulation gives predictable bite without the rotor wear or cold-bite issues that plague cheaper alternatives. For the money, it's a serious pad in a class that rewards drivers who brake late.
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.
