Definitely think its an extreme weight transfer issue. I have the same carbotech set up, and since raising the front a bit to help with nose dive the issue is less apparent. Unrelated to this particular issue, I'm increasing my spring rates soon to a stiffer set up and think it should help by resisting nose dive as well.
