N40S
As the name implies the N40S falls inbetween the N35S and N45S. Also part of the “new generation” compounds the N40S shares all of its basic properties with the other compounds of this range, but gives a midpoint with concern to friction values and bite.
This further enhances the possibility to give every driver the specific compound best suited to his or her needs, and get the best feel for the brakes without sacraficing performance.

Friction average: 0.45 - 0.52µ
Temperature range: 300 - 800 ºC

N45S
The N45S is a compound with a very high initial bite. It is a good step up from N35S and has an exceptional response. The brake power itself
is also elevated so the difference between initial bite and maximum brake power is lower than N35S.
The driver only needs about 15 bar of initial brake pressure to create a very good deceleration and even at very high speed the driver still only needs to apply a fairly low amount of pedal pressure. The modulation is still good and controllable, and gives a good brake balance.

The compound is suitable for high-speed race cars with a very good traction and down force, but has also shown itself to be usable to achieve extreme braking power in WRC Rally cars. Even in wet conditions it has a great pedal feel, and it lets the driver keep a good rhythm of driving. However, take notice that hard pedal force can cause lock ups under special conditions.
It is also no problem with regards to water fade and even at high heat the fade is low. The very high initial bite enables the driver to stay shorter periods of time on the pedal, which is also a good way to reduce disc temperatures. If the traction is good the pad is an excellent option, however if the traction is lower, it can be too easy to lock up the wheels, especially in the front.
The N45S is like the other compounds, gentle to the discs, has a low wear and does not create heat cracks or other disc problems.

Friction average: 0.48 - 0.55µ
Temperature range: 300 - 800ºC
