Those cooling holes need to be with same dimensions in flexcaps so in 15" they will make already quite big holes to the capsel. If those holes are smaller plastic will go to white because it streches too much. Also in car tires the U-groove size is already guite small. It is difficult to make them hold so well, because the locking dont work with small groove.
I think also at this point there is no sense to drill any holes. If you drill holes you should different number of holes depending on the number of the holes or spokes on wheels. I might have tomorrow one clean solution for you if I receive the brackets I have ordered. I will put more data on that when I have it.
