Best Track day pad for M400

[kinetic]

Any opinions on the best Trackday brake pad for the Noble?
DS2500, Mintex 1155? Pagids etc...

The standard ones on the M400 are O.K and don't suffer much 'fade'but they don't last long! Anyone know which they are?

The standard pad on my M400 is a Ferodo 3432. Not sure what the best pad is. I don't believe that many folk have tried different pads.

Ferrodo DS2500 are good all round pads for road and track use.

There are other more extreme ones that would only be worth considering for track use.
