Build smooth street response with a wider useful temperature range
Wilwood 150-D1631K is a four-pad ProMatrix set built on the D1631 plate shape. The PM compound combines smooth engagement, low-to-moderate dust, and low noise with a temperature range suited to performance street driving, autocross, and track-day use on steel or iron rotors.
Key Features
- PM ProMatrix compound delivers medium friction with smooth engagement
- Friction response rises progressively as operating temperature increases
- Low-to-moderate dust and low noise support street use
- Wider operating range than Wilwood BP-10 compound
- Suitable for performance street, autocross, and track-day use
- Designed for steel and iron rotor surfaces
Fitment
No year-make-model fitment applies. Confirm every dimension, interface, clearance, load, and installation requirement shown below.
| Application Type | Requirements |
|---|---|
| Dimension Based | Select by the Wilwood D1631 pad plate and a caliper or brake package specifically documented for that plate. Confirm the .81-inch pad thickness, rotor material, operating temperature, and required clearance. No broad year-make-model fitment is assigned. |

About Wilwood
Wilwood Engineering develops brake systems and friction materials for street, competition, and specialty applications. Its ProMatrix compounds are selected by pad plate, caliper compatibility, rotor material, temperature range, and intended use rather than by a broad vehicle claim.

FAQ
What is the 150-D1631K?It is a four-pad Wilwood ProMatrix set using the D1631 pad plate and PM friction compound.
How many pads are included?The package contains four pads.
What is the pad thickness?Wilwood lists a nominal pad thickness of .81 inch.
Are the pads pre-bedded?No. They are supplied non-bedded and should be conditioned according to current Wilwood procedures.
What driving is the PM compound intended for?It is intended for performance street use and can also support autocross and track-day use within its documented temperature range.
What rotors can be used?Wilwood specifies steel or iron rotor surfaces for this compound.
Do these pads have a universal vehicle fitment?No. Selection is based on the D1631 pad plate, compatible Wilwood caliper or brake package, pad thickness, and operating requirements.
How should compatibility be confirmed?Match the pad plate and thickness to the current caliper or kit documentation and inspect the existing components before installation.
Installation Instructions
- Confirm the brake system calls for the D1631 pad plate and .81-inch pad thickness before opening the package.
- Raise and support the vehicle safely, remove the wheel as required, and inspect the caliper, rotor, seals, guides, and hardware.
- Install the pads in the correct orientation with the hardware and lubricants specified by Wilwood, keeping friction surfaces clean.
- Reassemble and tighten all components to the current brake-system specifications, then restore a firm pedal before moving the vehicle.
- Bed the pads against compatible steel or iron rotors according to current Wilwood guidance and verify safe braking operation.
