The Zimmermann Formula Zbrake disc was designed with the aim of teaming simple installation with optimum braking effect under high mechanical and thermal load.
The compound brake disc developed by Zimmermann accommodates the increased demands incurred by engine tuning and optimised chassis structures.

Your advantages:
• Excellent deceleration action and no distortion of friction ring at high temperatures
• Substantial weight saving and therefore less unsprung mass
• Floating mounting enables radial expansion of the brake disc under relatively heavy loads, thus preventing shielding and increasing resistance to heat cracks
• „Hot spots" prevented by optimised design of ventilation channels
• 1:1 exchange of original disc possible
• Not subject to registration: general ABE certification supplied with disc
• No conversion required for brake tuning

What This Product Is/Does:
The PFC V3 Front Slotted Brake Discs are high-performance brake rotors designed for the front axle. They are part of PFC’s V3 line, which implies enhancements over standard discs in terms of cooling, braking bite, and resistance to fade. These rotors are slotted—which helps keep the braking surface clean, prevent gas buildup, and improve bite, especially under spirited driving or track use.

Key Features And Design:
  • Size: 410 mm front diameter / 34mm thickness.
  • Slotted Design: Slots help evacuate brake dust, gas, and water, improving contact and braking performance.
  • V3 Specification: PFC’s “V3” designation suggests a certain level of performance optimization, possibly better heat dissipation, improved material metallurgy, and refinements over previous versions.
  • Compatibility: Designed to work with PFC centers/hats and mounting hardware as applicable. If this is part of a conversion (for example from ceramic to iron or upgraded iron set), the fitment should match OEM bolt patterns and hat dimensions.

Symptoms / When You Might Need These Discs:
You may want to replace or upgrade to these PFC V3 discs if you observe:
  • Brake fade during spirited driving or track use—i.e. brakes losing effectiveness when hot.
  • Warped feeling, vibration, or judder under braking—especially if the current rotors are worn, warped, or cracked.
  • Reduced bite or inconsistent feel—slotted discs can help by keeping pad contact cleaner.
  • Heavy wear, deep grooves, scoring on existing rotors.
  • Desire to upgrade from standard stock rotors to more performance-oriented setup.

Why These Are A Good Upgrade / Replacement:
  • The slotted design improves pad contact, especially under harsh braking or wet conditions.
  • V3 spec implies newer engineering, maybe better resistance to warping, better thermal stability, and improved life under heavy use.
  • For drivers who track their Porsche or drive in demanding conditions, these discs will likely offer more consistent braking feel and fewer issues with fade or gas buildup.
  • Offers a cost-effective alternative to ceramic systems while still delivering strong performance.

PCCB iron disc replacement

Ever since the disc brake was invented vibration and pulsation caused by thermal expansion has been a major issue giving rise to warped discs - until now?

PFC has released new V3 disc and hat technology. The advanced design features a patented attachment design that uses a retention ring that holds the hat and disc together.

The ring means no need for torque wrenches, and no hassle. The ability to change a disc quickly and efficiently saves time and effort. As well as being convenient, the new V3 technology is much lighter than previous designs, making it easier to put on and pull off, and making the vehicle lighter.

This V3 disc retention method is based on the use of a two-turn retaining ring, which is held in a groove in the hat that overlaps the disc flanges – effectively locking the disc to the hat.

● Exceptional manufacturing standards - Run out less than 0.0254mm, Thickness variation less than 0.00762mm. Surface finishes less than .7 microns.When used in conjunction with Z rated fast road/track day pads, component life and on track performance markedly improved over competitors pads.

About SPORTS Brake Disc

Experience race-inspired stopping power with Porsche sports brake discs from Design911. Designed for performance driving, these upgraded brake rotors provide greater heat dissipation, improved bite, and enhanced fade resistance, ensuring confidence under even the most demanding conditions.

What They Are & What They Do
Sports brake discs (or rotors) are precision-engineered components that work with brake pads to generate friction and stop the car effectively. Unlike standard discs, sports variants are often drilled, grooved, or slotted, helping to vent heat and gases, improve braking response, and maintain consistent performance during high-speed or repeated stops.

Why They Fail
Over time, brake discs wear down from heat cycles, friction, and corrosion. Common signs of failure include scoring, warping, cracking, or vibration during braking. Track use or aggressive driving can accelerate wear, while low-quality discs may develop hotspots and fade under stress.

Why They Should Be Replaced
Replacing worn or damaged brake discs restores optimal braking efficiency, pedal feel, and vehicle control. New sports discs not only improve performance and safety but also extend pad life and reduce fade, ensuring Porsche’s legendary stopping precision. Design911 offers genuine Porsche discs for factory performance and aftermarket upgrades for enhanced durability and responsiveness.

Whether you’re restoring a classic 911 or tuning a Cayman or Taycan for track use, our range of sports discs combines precision, reliability, and performance to keep your Porsche braking like new.

Aftermarket Performance Brake Discs
High-quality aftermarket discs featuring slotted or drilled designs for superior airflow, reduced fade, and consistent friction performance.

Front Sports Brake Discs
Heavy-duty front rotors built to handle intense braking loads, offering maximum stopping power and stability under pressure.

Rear Sports Brake Discs
Rear discs designed for balanced braking and improved heat management, ensuring control and composure under repeated deceleration.

Drilled & Grooved Brake Rotors
Advanced rotors engineered to dissipate heat, clean brake pads, and deliver responsive braking for track and fast-road applications.

Motorsport & Track Brake Discs
Race-grade rotors made from high-carbon or composite materials, offering unmatched durability and thermal control for competition use.
