Just a little update, Been talking with EBC about the disks and pads I'm running from them. They have said I shouldn't be getting any issues with the disk and pad setup. They said the yellow stuffs are good for 700* temps, after some brain storming we think its the disks getting tired. The run out in the disk increases with the heat causing the judder and after 3 sets of yellow stuff pads they think its about time to refresh those front disks. Interestingly they also said don't go for the red stuffs.
