He said that installing spacers , either of the 2 types , causes the car to flex differently , putting forces on the suspension and other parts of the car that it was not designed for. The car was designed for a specific wheel base and width and that I should not mess with that. Any thoughts?
the wheel rate will change, so from a factory suspension geometry point of view, he is correct.
also from the wider track the wheel bearings and maybe the axles will take more abuse from the drivetrain point of view.

but that's no different than getting aftermarket wheels with more aggressive offset. i think most cars will be able to take 10-15mm with no issue. 20-25 is getting kinda aggressive. 30+ you're probably asking for trouble.
