87 Turbo Rotor Replacement.
 

I have a friend with an 87 Turbo, and she needs her rotors replaced. Her dad says that it is beyond his technical ability, and I'm just wondering if there is any real reason why this is complicated. I don't know much about the car, but I'm assuming it doesn't have ABS or anything that would make it difficult. Do the studs press into the rotors? do the rotors screw on, or are they floating? Is there any reason I shouldn't be able to do this with more than just basic tools? TIA
