The compound
WinmaX WP2.
Built for 4WD towing and high-GVM work rather than circuit racing. The priority is consistency under sustained load — long descents with weight behind the car — not peak friction on a race track.
Operating range0–600°C
Friction µ0.36–0.39
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 WP2. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
