6?i think it is more than 6 holes.. if ur talking about 5 to 4 lugs.. the only possible way is using 1 hole out of 5.. in which need to add 3 more holes.. and to do that u need to have the same pcd as such  5 holes pcd 114.3 to 4 holes with the same pcd 114.3.. 5x100/4x100.. my current rims is also 4/5 holes of pcd 114.3.. they usually address it as 9 holes as it accommodates 4 and 5 holes with the same pcd but actually it only hav 8 holes..
