D1 drift compound. SE3P rear caliper, DB1671 window.
Consistent drift-spec bite from Project Mu's dedicated D1 compound for the RX8 rear.
Fitment data still being indexed for this product. Ask BuildBot for a fit-check against your vehicle.
Generic pads compromise between street manners and performance. The D1 compound is built around one job — predictable, repeatable rear brake behaviour under drift conditions. That specificity shows in how the pad responds when you need modulation, not guesswork.
A drift-specific compound with very high friction — 0.50–0.55 — and a deliberately low 380°C ceiling. Project Mu specify it for the rear axle only. Fitting it to the front is a mistake: the ceiling is far too low for front-axle work on a circuit.
These are the compounds we stock for the Mazda RX8 rear whose published friction and operating temperature come closest to Project Mu D1-SPEC. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
