Ok I plan to swap to rear disks on my 91 GTI before long. I already have the P-valve on the rear beam so I don't have to worry about that. Well I have heard that when you swap out the rear disks that the lines will lack about 6" of meeting up with the p-valve? Is this true? I only plan to swap out the stub axles and not the whole beam. Will I still run into this problem? Can someone please explain in detail what the whole story on this is? Pics would really help also.
