What size hub adapter would i have to use if there 15-7j
Porsche use (5x130) we use (4x100) the proper way to sort them is to change the hub to a VR6 5x100
VR6 larger CVs and matching 5x100 hubs or early passat hubs 5x100 then do the adaptor to (5x130)
There are companies that can machine off something, but
its not safe due to the pattern stud offsets being 4x100 already! Not saying it can't be done, but with certain forces, drilling brake discs and wheel bearing stress the thickness of the adaptor plates would be lets say quiet thick to cope with a direct adaptor to cope with the mixed stud pattern!
Christmas Hols Kai, family been away for awhile, just catching up we had no tinternet and can't stand using 3G just to read mail!
All good though, no electronic gagets to bog the mind down, just the phone to pick up messages.
