Why this part
Budget pads fade when the rotors get hot and stay faded. The HC-EP compound recovers quickly between corners, so the pedal stays where you left it. For an RX8 that sees both the street and a track day, it's the compound that doesn't ask you to choose.
The compound
Project Mu HC-EP.
Effectively HC+ tuned toward the road, with the same friction range and a 600°C ceiling. Works from ambient, so it behaves like a street pad in traffic while still tolerating trackday use.
Operating range0–600°C
Friction µ0.43–0.58
Cross-brand equivalents
Run something similar.
These are the compounds we stock for the Mazda RX8 front whose published friction and operating temperature come closest to Project Mu HC-EP. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
