Hey. I've bought some spacers for my golf cab 4 stud. They are 30mm front and 35mm back. They are spacers and adapters so I can have 5 stud alloys. They have bolts with them that attach them to the car and u presume that the bolts that come with the alloys will fit the wheel to the spacer but one of the holes goes straight through the spacer. So, I need a stud for each wheel that is long enough to go through the alloy, the spacer and the hub of the car. I'm clueless as to what I need but I'm guessing the back will have to be bigger because of the 5mm difference in the spacer. Can anyone help me and give me some links to buying them? Cheers
