Ferodo has three different pad compounds for the F3X 3 and 4 Series

Ferodo DS2500:


The DS2500 is currently the best hybrid track/street pad 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. 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, autoX, and maybe some light track duty on street tires, the DS2500 is tough to beat.



When used on fast, heavy cars on the track with race tires, pad wear rates tend to be higher than some of the full track pad compounds. Under those conditions, Essex would recommend the Ferodo DS1.11.

Ferodo DS1.11:


The 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.


DSUNO

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.

Hi HP, I'm glad to see you guys are still around! I have a question about these pads. I purchased these from a friend (brand new), and installed them. However the noise was unbearable. Is it possible that I didn't do the bedding procedure correctly? I've used pads like Hawk HP+ and they were nowhere as loud as these. I took them off right away. Any solutions?

Are you referring to the DS2500?

DS2500 should not be noisy but I have heard it once in a while that are as loud as some of the full race pads.

Try to do your standard bed-in and see if the loud noise goes away.
