Porsche 914/4 - 1973 to 1976
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 (1973–1976) owners who want modern motorsport-grade braking while retaining OE hubs and factory balance.

Advanced Carbon Ceramic Technology
At the heart of this braking system are the latest generation 9m carbon ceramic discs, manufactured using long-strand carbon fibre reinforced with silicon carbide. This sophisticated construction delivers extraordinary strength, exceptional wear resistance and industry-leading thermal stability.
Unlike conventional cast iron brake discs, carbon ceramic rotors are capable of maintaining outstanding braking performance even under repeated high-speed stops, making them ideal for spirited road driving, track days and endurance use.
Precision Floating Disc Design
Each rotor features a lightweight two-piece floating design, incorporating centre bells CNC machined from 6061-T6 billet aluminium.
The billet bells are:
- Precision CNC machined.
- Hard anodised for corrosion resistance.
- Exceptionally strong and rigid.
- Lightweight to reduce rotational mass.
- Designed to accommodate thermal expansion during extreme braking.
This floating construction improves braking consistency while reducing stress throughout the braking system.
Why Upgrade to Carbon Ceramic Brakes?
Carbon ceramic braking technology offers significant advantages over traditional cast iron brake systems.
Benefits include:
- Approximately
16kg reduction in unsprung weight compared with cast iron discs.
- Sharper steering response.
- Improved suspension performance.
- Faster vehicle direction changes.
- Increased acceleration due to reduced rotating mass.
- Enhanced ride quality. Improved overall vehicle dynamics.
Reducing unsprung weight allows the suspension to react more effectively to road surfaces, improving grip, handling and driver confidence.
Exceptional Heat Resistance
During repeated heavy braking, conventional steel discs gradually lose efficiency as temperatures increase.
The Ninemeister Carbon Ceramic system is engineered to
withstand:
- High-speed road driving.
- Mountain roads. Fast road touring.
- Repeated track sessions.
- Extreme braking temperatures.
- Sustained high-performance driving.
The carbon ceramic construction delivers outstanding thermal stability, allowing the braking system to provide consistent stopping power without fade, even under the harshest conditions.
Outstanding Durability
One of the greatest advantages of carbon ceramic technology is longevity.
When properly maintained, the discs offer:
- Exceptional wear resistance.
- Outstanding corrosion resistance.
- Potential service life measured in hundreds of thousands of miles under normal road use.
- Reduced maintenance requirements.
- Long-term ownership value.
This makes carbon ceramic brakes an investment that continues to deliver performance throughout the life of the vehicle.
Benefits
Installing the Ninemeister 9m Carbon Ceramic Big Brake Kit
provides:
- Dramatically improved braking performance.
- Superior pedal feel.
