Why this part
Budget pads fade when the rotors get hot and stay hot — the H21 compound is engineered for exactly that condition. Project Mu's racing range is built to a performance specification, not a retail price, which shows in pedal feel and consistency across a full session. For drivers running Wilwood Superlite hardware seriously, this is the compound worth speccing.
The compound
Project Mu H21.
Project Mu’s endurance answer, and the compound with the strongest reputation in oval racing — particularly short circuits. It gives up some outright friction to H20 in exchange for excellent fade resistance, strong modulation, long pad life and unusually low rotor wear. Used in GT, V8 Supercars, NASCAR and Trans Am, front or rear.

These are the compounds we stock for the Wilwood Superlite 7416 / 7420 whose published friction and operating temperature come closest to Project Mu H21. 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
Partial match150–850°Cµ 0.45–0.55
Sprint and time-attack. More outright bite than M119, but it wants heat in it first.
Matched on published operating temperature only — one of the two brands doesn’t publish a friction figure, so this is a weaker comparison.
From $508WinmaX W7
Partial match100–850°Cµ 0.48–0.53
The top of the W-series — professional circuit and rally use, and the highest friction WinmaX publish.
Matched on published operating temperature only — one of the two brands doesn’t publish a friction figure, so this is a weaker comparison.
From $508Circo M111
Partial match180–780°Cµ 0.31–0.49
A circuit compound aimed at ABS cars, with a very wide friction range.
Matched on published operating temperature only — one of the two brands doesn’t publish a friction figure, so this is a weaker comparison.
