How universal are the Porsche wheels....... do wheels from a 996 easily bolt to a 997 ?

(ie, do all Porsche 911 wheels fit all models)

 

Within the porsche line, all the 5 bolt stuff will physically bolt up, but you may need spacers as the offset did change from year to year and model to model. I don't think you will need any spacers going from a 996 to a 997, that should be a straight bolt up.
