what is the techincal terms for the stud patern amd offset of an xy if any one knows them as i am trying to buy some after market wheels and want to avoid using hubs

not sure on the offset specs, but they are the same al the way up to the e-series rims - so any mag which will fit EA/B/D/F/L will fit the XY offset... if that helps at all

remember XY's use the small hub (centre hole) unlike the large XB-XC size
