Track Pad material help?!

loufitness

I keep getting brake shudder while on track...any others with this issue?

Setup:
2014 Sport, XP10/8, Blank Rotors, RBF600, Steel Brake lines, on RE-11 Tires.

I tend to be hard on the brakes and have been coached to not brake as late and aggressive. Front rotors replaced 3 times in an effort to correct the issue; stock rear rotors still.

It has been suggested to me to try different pad company.

Thoughts, suggestions, comments?

I have had this in the past when I went to Endless ME20 pad compound. My brake specialist suggested that it was due to the interaction between the pad deposits from my road pads affecting the bedding and operation of the ME20 pads which are an endurance race compound.
I went back to using a fast road pad front and rear (Project Mu HC+ or Ferodo DS2500) all the time and the problem went way. Byproduct is lots of dust though
What pads are in the car for Daily usage ?? I suspect the shudder is coming from the interaction between DD pads and XP10/8 combo on track and maybe it might work if you use a Carbotech DD pad if there is such a thing (I'm in Australia and not familiar with that brand of pad material)

Yes, Carbotech has a street pad. Xp 1520 from what I remember.
