This exact thing happened to me. Apollo, seemingly in response to this type of thing, upgraded the bolts on the Phantom so the bolts have full heads. I replaced the stock disc rotors but kept the OEM bolts. The ones that came with the Ghost are shallow & covered in Loctite. If you're not using Vanadium steel allan keys, you'll strip them easily. Good video - but it also brings back memories of the blisters I got due to using a smaller drill.
