Stock Wheel Offset
What is the stock wheel offset? The space between the hub mounting surface and the wheel center of Porsche 997 GT3 wheels. If you need a different offset use Wheel Spacers (Amazon link)
Generally, a good half of OEM wheels are correctly fitted only for certain cars, so be attentive!

And in case you see the inscription that ends with “ET” you are in the right place. This Porsche 997 GT3 wheel spec may be printed as both “number+letters” or vice versa.
Center Bore (Hub Bore)
The hole in the middle of a rim that exactly matches the hub diameter. It is located at the back of the wheel and as the car's hub goes into this hole it ensures the wheel gets centered correctly. Stock 997 GT3 wheels have a perfect centerbore fit with the hub. How to fit rims with a larger centre bore? Use Hub Centric Rings (Amazon link).
Custom Offset Range
It is calculated from the data of modified Porsche 997 GT3 that switched to custom wheel size preserving the proper driving capabilities of the vehicle.
