When it comes to high-performance driving, especially on the track, the choice of brake pads is paramount. It’s not just about stopping; it’s about control, consistency, and confidence lap after lap. Among the myriad of options available, the Ferodo DS range stands out as a benchmark for serious enthusiasts and professional racers alike. Within this esteemed lineage, the Ferodo DS1.11 brake pad has carved out a significant reputation, particularly for its exceptional performance in demanding, high-temperature environments and its remarkable endurance capabilities. Understanding what makes the DS1.11 unique, its strengths, and how it compares to other leading compounds is crucial for anyone looking to optimise their vehicle’s braking system for track domination.
What Exactly is the Ferodo DS1.11 Brake Pad?
The Ferodo DS1.11 is a high-performance racing brake pad compound meticulously engineered for the most arduous track conditions. Its defining characteristic is its ability to perform at the absolute highest temperatures without experiencing any noticeable fade. This fade resistance is critical in motorsport, where sustained heavy braking can push conventional pads beyond their thermal limits, leading to a dangerous reduction in braking power.
Developed to cope with the immense heat generated during aggressive track use, the DS1.11 compound maintains its friction coefficient consistently, providing reliable stopping power even when the discs are glowing. This makes it an ideal choice for disciplines such as GT racing, Touring Car championships, and Formula car series, especially in longer endurance events where braking systems are subjected to prolonged, intense stress.
Beyond its thermal stability, the DS1.11 is also remarkably kind to brake discs. Its formulation leads to a low wear rate on the discs themselves, which is a significant advantage for racers. Reduced disc wear not only saves money on replacement components but also ensures more consistent performance over time, as the disc surface remains optimal. Furthermore, the pad's own wear rate is also low, meaning less frequent brake changes are required, allowing teams and drivers to focus more on racing and less on maintenance during an event.
Is the DS1.11 a Good Pad Compound? A Deep Dive into Performance
The question of whether the DS1.11 is a 'good' pad compound can unequivocally be answered with a resounding yes, provided it's used in its intended application. It's not a general-purpose pad; it’s a specialised tool for high-performance track use.
Performance Characteristics
- High Temperature Stability: As mentioned, this is where the DS1.11 truly shines. It’s built to withstand and perform under extreme heat without fading, ensuring predictable braking even in the most demanding scenarios.
- Disc Kindness: Despite its aggressive performance, the DS1.11 is formulated to be gentle on iron discs, promoting their longevity and reducing running costs.
- Wear Rate: Both the pad itself and the disc wear are impressively low, making it an excellent choice for endurance racing where consistent performance over long stints is paramount.
- Modest Mu (Coefficient of Friction): The DS1.11 has a moderate coefficient of friction (mu) compared to some other aggressive racing compounds like the DS3.12. This means it might require slightly more pedal force to achieve the desired braking effect.
- Declining Torque Curve: As temperatures rise, the DS1.11 exhibits a slightly declining torque curve. For some drivers, this translates into a feeling that they need to push a little harder on the brake pedal as they dive deeper into a corner or as the brakes get hotter. Interestingly, many experienced drivers actually prefer this characteristic, finding it provides a more nuanced and controllable feel, particularly when operating closer to the ABS threshold or on less grippy tyres.
- Controllability: Some drivers find the DS1.11 more controllable, especially on street tyres, as it's less prone to activating ABS inadvertently compared to higher-mu compounds. This provides a more linear and predictable feel throughout the braking zone.
Crucial Compatibility Note: Iron Discs Only!
It is absolutely critical to note that the Ferodo DS1.11 compound is designed for use with iron discs only. It is NOT suitable for carbon ceramic discs. Using it with carbon ceramic rotors will likely lead to damage to the discs and severely compromised braking performance. Always ensure you match your brake pads to your disc material.
DS1.11 vs. DS3.12 vs. DS2500: A Comparative Analysis
To fully appreciate the DS1.11, it's helpful to understand its position within Ferodo's acclaimed racing pad lineup. Let's compare it with its siblings, the DS3.12 and the DS2500.
Ferodo DS3.12: The New Gold Standard
Released in 2019, the DS3.12 represents the cutting edge of Ferodo's racing pad technology. It was developed specifically to meet the demands of modern sports cars with higher horsepower, more sophisticated aerodynamics, increased curb weights, and stickier tyres. Here's how it stacks up against the DS1.11:
- Higher Mu: The DS3.12 boasts a higher coefficient of friction across all temperatures compared to the DS1.11. This means less leg pressure is required to achieve significant braking force.
- Flatter Torque Curve: Unlike the DS1.11's slightly declining curve, the DS3.12 exhibits an incredibly flat torque curve across a broad temperature range. This translates to exceptional consistency and repeatability; the brake pedal feel remains virtually identical lap after lap, corner after corner.
- Unfadable Performance: While the DS1.11 has outstanding fade resistance, the DS3.12 takes it a step further, showing no drop in performance at any temperature likely to be encountered on track.
- Superior Wear Rates: Dyno testing indicates that the DS3.12 offers superior wear rates compared to other Ferodo compounds, including the DS1.11, while remaining very kind to discs.
In essence, the DS3.12 is the more aggressive, higher-bite, and ultimately more consistent pad for those seeking maximum performance with minimal pedal effort. However, some drivers might find its higher initial bite and flat torque curve less communicative than the DS1.11, particularly on street tyres where ABS activation can be an issue.
Ferodo DS2500: The Hybrid Performer
The DS2500 occupies a different niche within the Ferodo lineup. It's widely considered one of the best hybrid street/track pads on the market. While we always advocate for dedicated race pads for serious track duty, the DS2500 offers a compelling balance:
- Moderate Bite & Fade Resistance: It provides a moderately high bite and solid fade resistance, allowing for spirited street driving, canyon runs, autocross, and even light track duty on street tyres.
- Street Manners: Crucially, it offers relatively low dust and noise levels for a performance pad. While it can still produce some squeal on certain vehicle platforms, it's significantly more street-friendly than the DS1.11 or DS3.12.
- Wear Rates for Heavy Track Use: When used on track by heavier, high-horsepower cars (3,000+ lbs) with R-compound tyres, the DS2500's wear rates tend to be considerably higher compared to the DS1.11 or DS3.12. For extended wear and ultimate performance under these conditions, the dedicated racing compounds are recommended.
The DS2500 is an excellent compromise for those who primarily drive on the street but occasionally venture onto the track. However, for a dedicated track car or for endurance events, the DS1.11 (or DS3.12) is the superior choice for its sustained performance and lower wear rates under extreme conditions.

Maximising Performance with DS1.11 Pads
To get the best out of your Ferodo DS1.11 brake pads, consider the following:
Proper Bed-In Procedure
Regardless of the pad compound, a proper bed-in procedure is essential. This process transfers a layer of pad material onto the brake disc, which is crucial for optimal performance, consistency, and longevity of both the pads and the discs. For racing pads like the DS1.11, the bed-in typically involves a series of progressively harder stops from increasing speeds, allowing the brakes to cool between sets. Always follow the manufacturer's specific recommendations, as an improper bed-in can lead to judder, reduced performance, and accelerated wear.
Cooling and Maintenance
Even the best brake pads benefit from adequate cooling. Ensure your vehicle's brake system has sufficient airflow, especially for prolonged track sessions. Regularly inspect your pads for wear and tear, checking for even wear across the pad surface. Uneven wear can indicate issues with caliper function or disc run-out. Also, regularly check and, if necessary, bleed your brake fluid. High temperatures can degrade brake fluid, leading to a spongy pedal feel or even complete brake failure due to boiling fluid.
