Saying this with respect but this has nothing to do with wheel
size. Are there any max wheel weight threshold available anywhere? If 'true' that the wheel on its own is the issue then Porsche would have released those weight/ratio figures.
Instead of covering up a faulty structural integrity simply caused by down-force on the '97 (in my uninformed opinion mind you). Unless a silly wheel is heavier than the constant downforce these car cope with at speed then I'm clueless man
