Match the brakes and suspension actually fitted to the car. Changed struts, hubs, uprights or previous brake conversions need a separate fitment check.
The 20 mm and 24 mm rear versions are different systems. Match the complete rotor and caliper combination rather than choosing by model year alone.
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 for the rear axle
- Two Narrow Dynapro-P radial-mount four-piston calipers, in the selected finish.
- Two 11.42-inch (290 mm) one-piece vented rotor/hat assemblies in the selected surface pattern.
- BP-10 pads for both rear service-brake calipers.
- Caliper mounting brackets, installation hardware and braided stainless steel rear flexlines.
| Caliper | Narrow Dynapro-P radial mount; four pistons per caliper |
|---|---|
| Rotor requirement | 11.42-inch (290 mm) diameter × 0.80 inch (nominal 20 mm) |
| New rotors | Two, included |
| Pad compound | BP-10; pad shape 4812 |
Parts retained
The compatible original rear hubs are reused. This is a service-brake kit, without replacement hubs, parking-brake cables, a master cylinder or brake fluid. The installer should check the condition and operation of the car’s parking-brake system during the work.
Questions before ordering
Does this include both rear sides?
Yes. Calipers, pads, brackets, installation hardware and rear flexlines are supplied for both rear service brakes. Two new rotors are also included.
Do I need to change the master cylinder?
Wilwood permits the stock OEM master cylinder for the specified Porsche 911 installation. Confirm the front and rear combination with your installer, who must verify pedal travel and brake balance before use.
Installation Documents
Installation instructions and clearance drawings open in a new tab.
