i know someone who had them,
bottom line is he prefered the Ferodo DS2500 pads better.as do most people here.

if u want pads,get ferodo ds2500s
 
i used mintex extreme on the track and killed a brand new set in a few 20 mins sessions, ds2500 handle the heat on the track so much better and dont kill discs aswell

ds2500 all the way
