Porsche 914/4 - 1970 to 1972
Rigid Powerlite PL4R Front Brake Kit using OE hubs
Many of the Porsche 914 sports cars that continue to be driven today are now modified with more power than the original VW flat four-cylinder engine. With that added power comes the need to upgrade the braking system and Wilwood Disc Brakes has the perfect solution.
New front brake kits are now available for 1970-76 Porsche 914/4 when used with a 914/6 or 911, 19mm master cylinder.
Kits include forged aluminum Powerlite four piston calipers, brackets and hubs, combined with larger plain face or SRP drilled and slotted vented rotors. Wilwood’s upgraded brake kits weigh substantially less than the smaller, unvented factory brakes with iron calipers and will help with the power and performance of your Porsche 914
Kit Features:
- Forged aluminum calipers are lighter and stiffer than cast iron and have been proven over decades in countless road races, rally and off-road competitions
- Aluminum mounting rotor adapters, brackets and hubs make the kits substantially lighter than stock while increasing braking performance and stamina
- Wheel studs are included with the front kits (user to supply correct lug nuts for wheels being used)
- Rigid Powerlite four piston radial-mount calipers are engineered to improve braking performance and feature pistons size
Calipers: Powerlite PL4R
- Rigid Powerlite four piston radial-mount calipers are engineered to improve braking performance and feature pistons sized to maintain the 914’s proper front-to-rear brake bias
- Caliper profile allows fitment in many small diameter wheels and quick-clip top pad retainer allows fast pad changes
- Calipers are finished in durable gloss red or gloss black powder coat
- Rear kits include Wilwood’s MC4 mechanical parking brake in left and right-hand configuration, plus the needed cable kit
Rotors: Spec37 Plain or SRP Drilled & Slotted
- Larger and thicker vented rotors provide greater brake torque and resist thermal distortion with curved vanes that circulate cooling air
- Both front and rear rotors are 289mm x 20mm (11.38”x0.81”) premium proprietary Spec37 iron alloy rotors with 36 curved vanes
- Both front and rear rotors are available in a precision plain face or SRP drilled and slotted patter
Brake Pads: BP-10
- BP-10 street performance pads provide smooth and consistent response with long wear over a broad range of temperatures
Installation Parts:
- Kits include caliper brackets, Flexlines and premium grade installation hardware
Why Upgrade to Forged Powerlite PL4R?
- Forged Strength: Lightweight forged aluminum calipers resist flex and heat.
- Compact Design: Quick-clip pad retainer allows fast pad swaps and clearance inside smaller wheels.
- Rotor Options: Choose plain vented rotors or SRP drilled & slotted with protective e-coat.
- Durability: Stainless steel pistons slow heat transfer and resist corrosion.
- Style: Calipers available in gloss black or red powder coat.
- Complete Kit: Includes calipers, rotors, brackets, pads, stainless flexlines, and hardware.
Ideal For: Porsche 914 (1970–1972) owners who want modern motorsport-grade braking while retaining OE hubs and factory balance.

- Support balanced braking performance during aggressive driving.
By using components engineered to work together, braking confidence and control are significantly improved.
When Should Carbon Ceramic Rear Discs & Pads Be Replaced?
Even advanced carbon ceramic systems require inspection and servicing.
Replacement Is Recommended When:
- Pad material reaches minimum safe thickness.
- Braking feel becomes inconsistent or less progressive.
