Ferodo DSUNO FCP4664Z Porsche 991 GT3/Turbo S, GT4 (Front)
FCP4664Z
Ferodo Racing has made great strides in pad development over the past few years, and DSUNO is their latest offering. For our customers who enjoy the performance of the DS1.11, but just want a little more bite, we recommend the DSUNO. It doesn't wear quite as long as the DS1.11, but it does offer a higher overall mu once it reaches track temperatures.

Description
Several brake pads on the market boast 'ceramic' technology. DS1.11 is the real thing. It is based upon a chemical family known as Siloxanes. Unlike carbon based materials, siloxane chains do not decompose at high temperatures and so DS1.11 keeps on working up to the highest temperatures a brake pad could ever see. That means it won't fade and has excellent life, the best in the Ferodo Racing range. Moreover the performance remains exactly the same throughout the pad's (long) life. It is formulated to provide a very flat friction profile at a medium/high level of friction. The pad compression is very low, always, and so pedal travel is short and consistent.
The main characteristics of DS1.11 are:High coefficient of friction (0,50) at all speeds and temperatures/li>
Excellent life of pad and disc/li>
High initial bite/li>
Predictability and control because of the unvarying torque output/li>
Low off-brake drag/Excellent release/li>
Unvarying performance throughout pad life/li>
Firm pedal. Always
All part numbers in the range feature a suffix. This suffix identifies the material compound available for each part number. Many part numbers are available in more than one material and are therefore listed accordingly on our website with different suffixes as explained below:
H = DS2500
C = 4003
R = DS3000
M = DS3000 Plus 03
E = DS3000 Endurance
W = DS1.11

Bedding & Installation
Please follow your vehicle service manual for installation instructions, or have the work performed by a qualified technician.
Ferodo's recommended bedding procedure:
During manufacturing, all Ferodo racing products are subject to “chemical bedding” to stabilize the materials and resins used in construction of the pad. Although this “prebedding” is an effective method and sufficient for low temperature use, the ultimate results are achieved by actual bedding on either the car or dyno...
How ? ...
This subjects the pad to the correct heat and torque loads seen in race conditions. These methods transfer pad material into the face of the rotor leaving a “transfer film” the friction generated between the pad face and this transfer film determines the performance of the “bite”. Correct bedding also ensures that materials which may become compressible are stabilized with the heat and pressure to avoid a “spongy pedal”.
Why? ...
When bedding in the car always try to bed on used rotors. If bedding on new rotors follow the rotor bedding instructions of the manufacturer, as it is important to heat cycle them first before bedding the pads. After fitting the new pads prepare the car by blocking off 50 percent of the brake cooling / air ducts to speed the “heat up time”. When leaving the pit lane apply brake gently at low speed to ensure pads are fitted correctly, build up temperature progressively to approx 350° C (670° F). This enables the heat to distribute around all areas of the pad.
When brakes are at suitable temperature begin bedding process, achieve approximately 70 percent of race speed then perform 25-30 brake applications at half normal race pedal pressure holding on for 4 seconds. When this is completed use a slowing down lap to allow brakes to cool. Return to the pit lane and allow pads to cool completely, check rotor appearance. Transfer film should be constant around rotor face, any “patchy” deposit will result in brake pedal judder. The use of temperature paint on rotors enables more accurate bedding procedures.
