Product details
Upgrade both front brakes with Wilwood Forged Narrow Superlite 4R four-piston calipers and 12.19-inch (310 mm) vented rotors. The two-piece rotors use aluminum hats and fit the compatible original hubs.
Custom color orders: PMB will confirm your requested finish before the order is finalized.
Vehicle Fitment
| Porsche model | Years | Version / application | Required brake setup |

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.
Turbo and Turbo Look brake configurations are not covered by this listing.
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.
Watch: How to measure your 911 front strut mounts
See where to measure the front caliper mounting holes, then compare the result with the requirement in the fitment table.
Why choose this configuration?
The 12.19-inch rotor is larger and thicker than the 11.10-inch rotor in the Powerlite front kit. The Superlite caliper also uses a larger 7416-shape pad. This is an option to consider when planning a complete brake upgrade, provided your wheels clear and the front/rear system is matched; it is not a guarantee of shorter stopping distances.
Parts supplied for both front sides
- Two Forged Narrow Superlite 4R four-piston calipers in the selected finish.
- Two 12.19 × 1.10-inch vented iron rotors and two aluminum rotor hats.
- BP-10 brake pads for both front calipers.
- Application-specific mounting brackets, rotor/hat and caliper hardware, and braided stainless steel flexlines.
| Caliper | Forged Narrow Superlite 4R; four pistons per caliper |
|---|---|
| Rotor diameter × thickness | 12.19 × 1.10 inches (nominal 310 × 28 mm) |
| Pad compound | BP-10; pad shape 7416 |
| Caliper mounting tabs | 3.5 inches (88.9 mm), center to center |
Parts retained and installation planning
The existing compatible front hubs and struts are reused. A master cylinder, rear brake kit, wheels and brake fluid are not included. Wilwood permits the stock OEM master cylinder for the specified Porsche 911 application, with the installer responsible for the complete system’s brake balance and pedal operation. The factory front dust shields must be removed for this installation and are not reinstalled, as specified in Wilwood’s instructions.
Installation Documents
Installation instructions and clearance drawings open in a new tab.
