Why this part
Channel: marketing:Project Mu Racing H16-03 Brake P Draft: Cheaper pads fade when the RX8's light kerb weight and high-revving character push braking zones hard on circuit. The H16-03 compound holds bite and pedal feel across repeated heavy stops where budget alternatives go soft. For drivers who actually use the track, the price gap closes fast when you stop replacing pads every second event.
The compound
Project Mu H16-03.
A carbon-ceramic race compound built for GT, TCR, WRC, historic racing and time attack. Its character is high initial bite with a clean release, which lets you brake hard without locking a wheel, and Project Mu specify it for both front and rear axles. The trade-off is pad life: it wears faster than H20 or H21, so it costs more per race weekend.
