Ferodo DS3.12 Brake Compound Details
Released in 2019, the DS3.12 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. The Ferodo DS3.12 is the modern pad compound designed from the start to explicitly to 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 that on every turn, on every track you drive, on every lap, your brake pedal is going to feel almost exactly the same, providing tremendous consistency and repeatability. The DS3.12 has a higher mu than Ferodo's other compounds, so not as much leg pressure is required to initiate the desired response. It is also unfadable, showing no drop in performance at any temp your brakes will ever see. In dyno testing, the DS3.12 has shown superior wear rates to the other Ferodo compounds, while remaining kind to the discs. We believe the DS3.12 is the gold standard to which other race compounds will be compared.
Ferodo DS1.11 Brake Compound Details
The Ferodo DS1.11 is a long duration endurance race pad that is also used in the Red Group of advanced track day drivers. With an incredible flat torque curve across the workable range of 392 to 1382 degrees. Designed to put you on the podium of your next WRL race or HPDE, the Ferodo DS1.11 is a track only pad that is designed for repeatable stopping performance and feel across a very wide temperature spectrum. The Ferodo DS1.11 brake compound makes the chassis repeatable in every brake zone, lap after lap.
The cold friction profile of the Ferodo DS1.11 is predictable and grows linear as your pad heats up with very good fade resistance all the way to its maximum 1382 F limit. Another common use of the Ferodo DS1.11 is an advanced track day driver in the red group in a well set-up chassis with sticky rubber and aero.
Ferodo DS2500 Brake Compound Details
Although we always recommend using a dedicated race pad for the track, the DS2500 is one of the best hybrid street/track pads on the market. It features the moderately high bite and solid fade resistance of a track pad, with the relatively low dust and noise levels of a street pad. When used as a street pad, it can produce some squeal on certain vehicle platforms. If you drive aggressively on the street, do some canyon runs, autocross, and maybe some light track duty on street tires, the DS2500 is tough to beat.
Ferodo DSUNO Brake Compound Details
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.

Porsche Carrera GT Front and Rear Pads
Precision braking starts here. The Carbotech CT991B brake pads offer world-class stopping power across a range of compounds engineered for HPDE, club racing, time trials, and daily driving. Whether you're shaving tenths at a national event or building consistency during weekend track days, there's a Carbotech compound tailored to your performance goals.
Manufactured in the USA using Carbotech’s proprietary ceramic and metallic formulations, these pads deliver unmatched modulation, rotor friendliness, and fade resistance.
Friction materials have evolved significantly over the years. Brake pads were originally made with organic ingredients such as asbestos and carbon, held together by a strong resin. Most brake pads sold today are considered semi-metallic, semi-metallic brake pads use brass, copper, and steel wool shavings held together by a resin. Unfortunately, the main drawback about the use of steel strands, iron, graphite, and small amounts of filer and friction modifiers (used to provide strength and conduct heat away from the rotors) is that the metal shavings and iron must rub against steel rotors every time the brakes are applied. This generates more noise and is a lot more abrasive on the rotors. It also creates corrosive dust that can damage your braking system as well as the paint on your wheels and car.
Friction materials that contain Ceramic Kevlar formulations have become recognized for their desirable blend of traits. This allows the Ceramic Kevlar pads to handle higher brake temperatures with less heat fade, and provide faster recovery after heavy braking. It also reduces brake dust and makes wheel maintenance easier!
Ceramic Kevlar compounds extend brake life compared to most other semi-metallic and organic materials, and at the same time they outlast other premium pad materials by a significant margin, without compromising in noise control, pad life, and all around braking performance.
The CT991B shape fits a variety of high-performance applications, making it a go-to solution for drivers looking for track day brake pads that match their skill level and intensity.

No. All Carbotech compounds are known for being rotor-friendly, helping reduce rotor wear and operating costs.
5. Which compound is best for endurance racing?
RP2 is engineered specifically for long-distance events where pad and rotor life are just as important as torque output.
6. Do Carbotech pads require special bedding procedures?
Yes. A proper bedding-in process is critical for optimal performance. Carbotech provides detailed bedding instructions with every set of pads.
Carbotech Brake Pad Bedding Procedures
The bedding process transfers friction material from the pads into the pores of the brake rotor. It also matches the microscopic contours of the pads and rotors to increase surface contact. Proper bedding of pads & rotors will result in greater performance, longer pad life & less rotor wear. Failure to properly bed in your pads could lead to friction materials chunking and breaking up. This could also lead to overheating your pads and causing them to glaze over resulting in the car not being able to stop or slow fast enough.
All new brake pads require a bedding process. The proper way to bed your brake pads and brake discs (rotors) is to bed them on the racetrack, NOT on the street. Start this process by pumping your brakes a few times to assure proper installation. Once on track perform several moderate (medium) near stops (to a very slow rolling speed) to thoroughly warm up the pads and rotors. This should take 1-2 laps. This allows a thin layer of the pad material to be transferred into the micro-grooves of the rotor.
After the pads/rotors are warm, perform a series of hard near stops (to a slow rolling speed) until some brake fade is felt. This process should take about 2-4 laps (depending on the track). Once this occurs, then stay off the brakes (as much as possible) and bring your car into the pits/paddock to completely cool. Do not lock the tires during this operation.
Allow brake pads and/or rotors cool down to ambient temperatures; no less than 30 minutes. The total bedding procedure should not take more than 5-6 laps or about 10-15 minutes. Failure to properly bed in your pads could cause friction material to chunk and break up resulting in poor pad performance and pad life. Improper bedding can also lead to overheating your pads and causing them to glaze over, resulting in the car not being able to stop or slow properly.

On the race track, there is perhaps no single safety system more important than your brakes. No single part of that system is more critical than brake fluid, given the extraordinarily high temperatures it operates under. At CMS Performance, we got tired of (and a little nervous) using "racing" brake fluid at the race track that didn't live up to its claimed performance when things got hot. We found more than a few brands whose product was all hype and not high performance.
No Hype. All Performance. No Kidding.
So we did something about it. CMS Performance RF1 is manufactured in partnership with Orthene, maker of the also-excellent Halo P1 racing brake fluid and a brake fluid supplier to many racing teams in Formula 1, WEC, and other professional series. RF1 was formulated to maintain consistent viscosity, lubricity, and compressibility at the extreme system temperatures and line pressures found in racing and track days.

A Word About Flushing Brake Fluid
All brake fluid degrades over time (not mileage), attracting water as it ages, which, at high brake temperatures, can lead to fluid boil and brake fade or failure. That's why the "wet" (aged) boiling point of any brake fluid is substantially lower than the "dry" (new) boiling point.
To maintain maximum braking performance, Competition Motorsport strongly suggests replacing your brake fluid before every track event, but at least every three months if you're consistently racing and/or driving at track days. It's cheap insurance against learning about brake fade the hard way!
