I am going to list the 19" and 20" charts since those seem to be the most popular orders by far. If you want to look at the 18" charts just let me know and I can point you in the right direction.
Each chart will have a list of widths, offsets and disk sizes.
When you pick the specific width you want, look right and find the offset you are looking for. Then look up for the specific "disk" that offset is under. And then right above the disks is a number in "mm". That number is the size of the lip you will receive if ordered in that desired offset and width.
So for example. Lets look at the SP5 chart. If you want to go with a 19x9.5 +25 HP disk wheel it will have a 69mm lip. Compared to a 19x9.5 +12 HP disk having an 82mm lip.
