Bad news aside, as we discussed through private messaging, it sounds like these wheels are not Porsche specific (i.e. hub centric) . In other words, they require the use of centering rings in order for them to properly interface with the center bore specification of your vehicle . Moreover, Forgestar probably uses an altogether different style lug bolt. However, unless these wheels require the use of spacers, the length of said lug bolts shouldn't be any different than that of the oem lugs (28mm's) . Makes no sense ? Anyway, sorry to hear about your situation. Best of luck sorting it out .
