Fitment questions?
Call (855) 786-7101 or text (801) 304-3141. We check fitment by VIN.
Product details
Replace the front calipers with four-piston Superlite 4R calipers while keeping suitable factory-size rotors. The package includes pads, brackets and braided hoses for both front wheels; rotors are not included.
Vehicle Fitment
| 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.
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?
- Retain serviceable factory-size front rotors while replacing the calipers, pads, brackets and flexible hoses together.
- 4-piston Superlite 4R calipers: forged aluminum bodies with stainless steel pistons.
- 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 Superlite 4R calipers in the selected finish, 4 pistons per caliper.
- 1 axle set of BP-10 brake pads, enough for both front calipers.
- 2 caliper mounting brackets with the specified mounting hardware and alignment shims.
- 1 front braided stainless steel flexline kit, part 220-16709, serving both wheels with the specified connection hardware.
Reused or purchased separately: Rotors are not included. Retain serviceable rotors of the correct 20mm configuration. 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. Bracket and caliper shimming are part of the alignment procedure; the kit is not an assembled hub/rotor unit.
Common questions
Does this kit include rotors?
No. Keep serviceable front rotors of the configuration specified in the fitment table. If your rotors also need replacement, ask PMB about the matching rotor-inclusive kit.
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.
