I think hes refering to breaking the chassis. It wouldnt really be any weaker than the coupe. The added weight is because of the greater chassis stiffening that ford did. But with either car should have sub frames, or a frame kit installed to prevent the chassis from flexing and screwing with the geometry of the suspension and alignment.
when i was putting my subrames on another mustang came up to have some exhaust work(was at a muffler shop a friend runs) anyway i went to help and i noticed that his didnt have a couple small braces that mine did. i dont think its alot though. i believe that most of the weight is because of the motor and other things involved with the top.
