The compound
Project Mu PCR09.
The Club Racer, and Project Mu’s trackday compound. It runs 300–800°C with 0.42–0.55 friction, and Project Mu state plainly that it is not for street use. The 300°C floor is the highest of anything we stock, so it is a strong pad once hot and the worst choice in the range for a cold first lap.

Run something similar.
These are the compounds we stock for the Wilwood Superlite 7416 / 7420 whose published friction and operating temperature come closest to Project Mu PCR09. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
Circo M127
Very close150–850°Cµ 0.45–0.55
Sprint and time-attack. More outright bite than M119, but it wants heat in it first.
Matched on published friction and operating temperature.
From $508WinmaX W6.5
Very close50–800°Cµ 0.47–0.50
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.
Matched on published friction and operating temperature.
From $494Circo M119
Very close50–800°Cµ 0.48–0.51
Circo’s sprint answer: around 0.5 friction from 50°C, so it works before the pads are hot. Rally and circuit.
Matched on published friction and operating temperature.
