Product details
Add Powerlite four-piston front calipers to compatible, serviceable factory-size rotors. This caliper-and-bracket kit includes pads and braided flexlines for both front wheels; rotors and hubs are not included.
Custom color orders: PMB will confirm your requested finish before the order is finalized.
Vehicle Fitment
| Porsche model | Years | Version / application | Required brake setup |
|---|---|---|---|
| 911 | 1969–1974 | M-type front struts | 3.00-inch front caliper mounts; serviceable 282 × 20 mm vented rotors |
| 914-6 | 1970–1971 | Factory six-cylinder | 3.00-inch front caliper mounts; serviceable 282 × 20 mm vented rotors |
Match the brakes and suspension actually fitted to the car. Changed struts, hubs, uprights or previous brake conversions need a separate fitment check.
Measure between the centers of the caliper mounting holes, not across the strut tube. Use the mounting distance specified in the table.
The 914-6 row applies to the factory six-cylinder front setup; it does not establish fitment for a four-cylinder 914 or a car converted to different struts.
A 15-inch wheel may clear, but diameter alone is not enough. Compare the exact wheel’s barrel and spokes with the wheel-clearance drawing before ordering.

What is included
- Two Powerlite four-piston calipers in the selected finish.
- BP-10 pads for both front calipers.
- Caliper mounting brackets and installation hardware.
- Braided stainless steel front flexlines.
Required existing parts
Use the compatible original 11.10-inch-diameter, nominal 20 mm-thick vented front rotors and factory hubs specified by Wilwood. Have the rotors checked for condition and service limits. Solid rotors are not a substitute. If you need new rotors with the calipers, choose the separate 140-16946 kit. The factory front dust shields must be removed for this installation and are not reinstalled, as specified in Wilwood’s instructions.
| Caliper | Powerlite; four pistons per caliper |
|---|---|
| Rotors supplied | None; compatible existing vented rotors required |
| Pad compound | BP-10; pad shape 7912 |
| Mount requirement | 3.00-inch (76.2 mm) M-strut caliper tabs |
Questions before ordering
Is this a complete rotor kit?
No. It supplies both front calipers, pads, brackets, hardware and flexlines. You supply the compatible serviceable rotors and reuse the original hubs.
Will this fit a 3.5-inch strut?
No. This 140-17019 kit is specified for M-type struts with 3.00-inch mounting-tab spacing. Measure before ordering.
Can I retain my master cylinder?
Wilwood allows the stock OEM master cylinder for the specified Porsche 911 installation. Your installer must verify the complete system’s pedal travel and brake balance.
