Why this part
Channel: marketing:Project Mu HC+ Performance Brake Draft: Cheaper pads fade when the rotors get hot and stay hot — exactly what happens on a track day. The HC+ compound is engineered for sustained high-temperature performance without sacrificing cold-bite on the first lap. For an RX8 that sees real circuit use, it's a straightforward upgrade over street-grade alternatives.
The compound
Project Mu HC+.
The most useful all-rounder Project Mu make for Australian conditions: usable from 0°C and rated to 800°C. That span is unusual — most pads with an 800°C ceiling need serious heat before they work at all. It is why HC+ suits a car that drives to the circuit, races, and drives home, and why it handles sprints where there is no warm-up lap.
