Product details

Refresh both front brakes with forged aluminum D45 two-piston calipers, new 11.10-inch vented rotors, BP-10 pads and braided hoses.

Vehicle Fitment

Vehicle fitment and required brake configuration
Porsche model Years Version / application Required brake setup
911 1969–1974 S-type front struts 3.50-inch S/A front caliper mounts; 20 mm front-rotor configuration
911 1975 Carrera 3.50-inch S/A front caliper mounts; 20 mm front-rotor configuration
911 1975–1977 S 3.50-inch S/A front caliper mounts; 20 mm front-rotor configuration
911 1978–1983 SC 3.50-inch S/A front caliper mounts; 20 mm front-rotor configuration
911 1983 Base 3.50-inch S/A front caliper mounts; 20 mm front-rotor configuration

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 installation sheet covers the 1975–1983 installation procedure. Earlier S-strut cars must still match the 3.50-inch mounting points and 20 mm front-rotor configuration.

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 kit?

  • Replace the factory S/A calipers with forged aluminum D45 units that use the original 3.50-inch mounting points, plus new 20mm-configuration rotors and hoses.
  • 2-piston D45 calipers: forged aluminum bodies with stainless steel pistons and dust boots.
  • BP-10 street-performance pads: a practical compound for everyday response and wear. Dedicated track use may require a different pad compound, fluid and cooling plan.

What is included?

  • 2 D45 calipers in the selected finish, 2 pistons per caliper.
  • 1 axle set of BP-10 brake pads, enough for both front calipers.
  • 2 vented rotors, 11.10 × 0.80 inches, in the selected surface pattern.
  • Direct-mount caliper fasteners for the original mounting bosses; separate adapter brackets are not required.
  • 1 front braided stainless steel flexline kit, part 220-17550, serving both wheels with the specified connection hardware.
  • Specified rotor/caliper installation hardware and hose fittings. Use the supplied connections; front D31/D45 installations require the new banjo bolts and crush washers in the kit.

Reused or purchased separately: Wheel hubs, struts/uprights, master cylinder, brake booster, wheels and brake fluid are not included.

Wheel clearance and installation

Wilwood lists a 15-inch nominal minimum wheel diameter. Diameter alone does not confirm fit: check the barrel and spoke profile against the wheel-clearance drawing and Figure 2, page 3 of the instructions. Maintain at least 0.080 inch (about 2mm) between the wheel and caliper in all areas.

The installer must check hose fittings, length and clearance through full suspension travel and steering lock.

Common questions

Does one kit cover the whole car?

No. Quantity 1 covers both front wheels. The opposite axle is a separate purchase; select it for your car’s actual brake configuration and evaluate the finished front-to-rear balance.

Do I need a different master cylinder?

Wilwood’s instructions permit the stock master cylinder for the documented application. The installer must still confirm pedal travel, system condition and front-to-rear brake balance, especially on a modified car.

Need help choosing? Ask PMB to check your Porsche’s brake configuration. Send the model/year, VIN, wheel size and photos of the installed brakes, plus caliper mounting-center and rotor-thickness measurements.

Installation Documents

Installation instructions and clearance drawings open in a new tab.

Installation must be performed by a person experienced in disc-brake systems. Follow the complete instructions for bleeding, bedding, testing and inspection before road use.
