All VW GOLF MKV's have the same stud pattern which is 112mm pcd and 5 stud.
Offset ET's will differ depending on the size and width of alloy you want.
A typical 7" to 8" wide alloy should have an ET of between 45 and 52 for a good fit. Typically the wider the alloy the lower the ET, down to 45.
You can go higher or lower, but you'll encounter rubbing issues especially with wheels over 8" wide.
