3. Project Mu PCR09

   4 options · from $306

   Project Mu’s Club Racer. A strong trackday pad, but with a 300°C floor it is the range’s worst choice for a cold first lap.

5. WinmaX W6.5

   1 option · from $494

   The standout for sprints and hillclimbs: close to 0.5 friction from a 50°C floor, so it bites on lap one. WinmaX call it their best rally pad.

   50–800°Cµ 0.47–0.50Usable from coldrally · sprint · hillclimb · circuit

6. Circo M119

   1 option · from $508

   Circo’s sprint answer: around 0.5 friction from 50°C, so it works before the pads are hot. Rally and circuit.

7. WinmaX W5

   1 option · from $405

Figures are the manufacturers’ own published data for each compound. Where a brand doesn’t publish a figure we say so rather than estimate it. From cold is our reading of each manufacturer’s published minimum operating temperature, not a separate rating they publish. Manufacturers test on their own equipment, so friction numbers are best compared within a brand rather than across brands. Not sure which suits your Wilwood Superlite 7320 setup?
