Ferodo Brake Pad Compound DS3.12
The DS3.12 brake pad compound is the latest evolution in Ferodo's incredible DS line. Sports cars today have more of everything: more horsepower, more sophisticated aero, higher curb weights, and stickier tires. These attributes place serious demands on a vehicle's brake system.
Ferodo 11 FRP1078GB-N Comparison Chart
The Ferodo DS3.12 is the modern pad compound designed from the start to explicitly handle those demands. Out of all the pad compounds we've ever tested, from all manufacturers, the DS3.12 shows the flattest torque curve across the broadest temperature range. That means on every turn, on every track you drive, on every lap, your brake pedal is going to feel almost exactly the same. This gives you tremendous consistency and repeatability.
Ferodo 11 FRP1078GB-N Coefficient of Friction (Mu) Chart
The DS3.12 has a higher mu (µ) than Ferodo's other compounds, so not as much pedal pressure is required to initiate the desired response. It is also un-fadable, showing no drop in performance at any temperature your brakes will ever see. In dyno testing, the Ferodo DS3.12 has shown superior wear rates compared to the other Ferodo compounds, while remaining kind to brake rotors.

PFC Replacement Slotted Disc V3 (Front) | Porsche 992 GT3 Cup/718 GT4 RS Clubsport
from $612.85
PFC Front Slotted Replacement Disc V3
Porsche 992 GT3 Cup/718 GT4 RS Clubsport
Dimensions: 380mm diameter, 34mm thickness
Brake disc only, does not include brake hat (fits on OEM hat).
Not for use in official Porsche Carrera Cup championships.
PFC has released their new V3 disc and hat technology. This advanced design features a patented attachment mechanism using a retention ring to hold the hat and disc together. This eliminates the need for torque wrenches, giving you a no-hassle solution to the need for a quick, efficient disc replacement.
In addition to being convenient, PFC's new V3 technology is much lighter than previous designs, reducing unsprung weight on your car.
This V3 disc retention method is based on the use of a two- or three-turn retaining ring, which is held in a groove in the hat that overlaps the disc flanges – effectively locking the disc to the hat.
PFC V3 Disc Features:
Reduced mass on disc connecting flanges, which reduces thermal distortion (more specifically, coning) at race temperatures. Reduced coning allows the pads to sit flatter on the disc, which better utilizes the available radial depth. There is better pad force distribution and the brakes will run cooler, reducing hot spots on the disc. This will also have the benefit of reduced taper wear of the pads.
More heat will be contained in the brake faces because there is less of a heat sink in the flanges. This reduces thermal stress at the ID of the disc and reduces the chance of thermal cracking to occur.
Consistent disc float from race beginning to end. As a race progresses with a bobbin disc, float will often be reduced when a bobbin is no longer sitting square in the disc. Reduced float will increase piston knockback, increase pedal travel and add vibration.
Reduced complexity. The number of brake assembly parts is reduced from 38+ for a bobbin drive disc to just 3 in a V3 disc assembly
Decreased assembly time. You can assemble a V3 race disc in a matter of seconds.

APEX Pro Gen II Lap Time Optimizer
APEX Pro is a tool for competitive drivers. From track days and road racing to autocross and hill-climb, APEX Pro is a tool that helps improve lap times while on track and simplifies post-session data review with the most intuitive software interface available.
APEX Pro pairs using Bluetooth with your Apple (iOS smartphone) to automatically save data to the APEX app. It provides accurate lap-times at over 200 official tracks around the world, as well as allowing custom track creation. While on track, precisely filtered data is logged at 10 Hz and sent to the smartphone. APEX has a suite of tools allowing drivers to review and replay data overlaid on track maps or plotted in many other ways. To compare laps with other drivers, simply email or AirDrop recorded sessions to fellow drivers or driving instructors. You can instantly overlay and compare sessions from the same track. While you're out on the track, friends and crew members can watch your driving and lap-times (and telemetry with Gen II) from anywhere in the world using the CrewView social platform (iOS).
The Ultimate In-Car Driving Coach
Red lights on the APEX Pro indicate unused potential. In motorsport terms, the tires are not at their limit. This limit is calculated by taking in thousands of sensor measurements per second from the internal GPS and accelerometers (nine-axis IMU). These raw sensor measurements are then filtered through the APEX algorithm derived from years of testing at all levels of motorsport. This process on takes a lap or two of driving at pace, and from these measurements APEX determines the car’s road-holding ability (based on your driving, not a theoretical limit).
That's how APEX helps you find your limits. Peak measurements are compared with the other measurements to determine if those peaks seen in one area of the track are achievable elsewhere. Put another way, you may be faster in one section of the track than another, and that is how APEX learns where the available grip is. Red lights represent the limit determined by the APEX algorithm, green lights show you how close you are to that limit. For more information, check out the APEX Pro startup guide linked below!
New APEX Pro Gen II Features
Smoother, more precise data (satellite map and data graphs).
Easier interpretation of APEX Coaching model (100% APEX score is possible!)
Predictive timing display option on the APEX LEDs.
Battery indicator light on the unit (green = fully charged).

Telemetry: live streaming of ground speed, longitudinal and lateral G data traces
APEX Pro Gen II Driver Benefits
Easy-to-interpret real time display (no more red lights on the straights if you get a good exit)
Lower profile means it takes up less space on the dash so your vision is not obstructed.
You now know if your APEX Pro unit is being charged when you plug it in, and whether it’s fully charged.
Predictive LEDs make it super-simple to see if you are trending faster or slower than your best lap so far.
Telemetry is perfect for track side instruction and endurance racing.
