Additional Information
DS2500 - DS2500 is amongst the foremost high performance track day pads in the business. It is also suitable for some light duty front and many rear pure race applications. It offers excellent refinement for such a high performance pad. The main characteristics of DS2500 are:
Track day & light race use for all vehicle types
Road style refinement but with race material ability to withstand heat with respect to life and µ
Average friction coefficient of 0.42 over working temperature range of 20°-500°C
Essex Recommendation - While its best to always run a dedicated pad for the track, 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 platforms. During aggressive driving the DS2500 is known for its flat torque curve, which means as temperatures go up, the response through the brake pedal remains consistent. 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.
ATTENTION: When used on high HP, heavier cars (2,800 lbs+) on the track with race tires, pad wear rates tend to be higher than on Ferodo Racing's other pad compounds. Under those conditions, its recommended to run DS1.11
DS1-11 - 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:
Heavy duty endurance material
Applications - touring car, GT, single seat
Average friction coefficient 0.46 over working temperature range of 200°-700°C
Long life
Very kind to discs
Essex Recommendation - DS1.11 is one of Ferodo Racing's latest endurance race pad offerings. It has slightly less bite at high temps. vs their older DS3000, but doesn't decompose nearly as quickly under extended heavy use on the track. The DS1.11 is known for its extremely flat torque curve, which means that as temperatures go up, the response through the brake pedal remains consistent. The DS1.11 can be thrashed all day without having it burn up or fade, it's easy on discs, and doesn't have many of the judder or vibration issues that competing products have. If you want an extremely solid, all around race pad that will perform well and last a long time, the DS1.11 is the perfect choice.
WARNING : DS1.11 Is not suitable for road use
