I have found the CF used in the chassis is no were near the quality it is should be, I have had two problems. One, a small chunk is was removed on the bulge for the droop screw this was a very clean run didn't hit any thing (video to confirm) .21 consistency and the chassis at the back has de-laminating (it was sealed too) again hit nothing with a .29 consistency. I work at my LHS and have gotten a quite a few complaints both at the track and in the store, 90% of the claims were from the first batch if that matter
