How far is the top of the steerer tube below the top of the stem? The steerer should be nearly, or better yet fully, supported inside the stem and a gap of only about 3 mm left for headset adjustment. Full support is really recommended if the steerer is carbon and if possible have the steerer extend slightly above the stem and use a small spacer to get the required gap.

BTW, I count 70 mm of spacers below the stem and, if that's correct, that's more than any carbon steerer is supposed to have. A maximum of 50 mm is the highest stack I've ever seen any maker allow and that's with a 1-1/8" steerer. If you really need that much you probably need a larger frame.
