This is a common problem, not only with Panasport caps. The front hub length+grease cap make it difficult for center caps to fully seat within the hub center bore.

What style cap are you using, there are "ribbed" and "hex style".The hex style are very shallow.

There are few approaches:
-compress grease cap so that surface is more flat
-use a rubber-type grease cap...this gives you a flexible surface unlike the rigid metal ones
-have a cap adaptor made to gain clearance
-lastly, if clearances allow, a traditional wheel spacer. I'd use this as a last resort.
