Tap the cap back in. being sure to keep the cap square, and only put it in as far as it needs to go to clear the center cap.

The channel locks, wacking on the handle end with a 3 lb sledge, work to remove the the cap. Wacking with a chisel works as well. You will get little movement at first, but work your way around the cap in 90-180 degree intervals. A block of wood would do less damage if you have a nice oak piece like dr. bob mentions, that can take a pounding. The former methods mark up the cap, but it's hidden. Porsche has a tool the clamps over the ridge on the cap. My 89 caps do not have the promnouced ridge that Keith GTS caps have, so are a bit harder to remove.
Anyway, flattening the dome worked for me. I have concave center caps, so I had to even dimple the dome concave a little for them to fit.

Mine were made for me by the wheel manufacturer. They are milled from billet aluminum. Find someone with a milling machine/lathe and have them made. Should be cheap enough (though mine weren't).
All you need is about 6 or so mm as stated. You can remove the dust cap. Grind off the lip and then grind off the base edge until you have removed 6mm or more of material. Square the top of the dust cap also without distorting it's shape. Then squarely tap in a bit and then test fit the wheel with it's cap. If not in far enough, tap the dust cap in a little more until it fits. Just don't drive the cap home with the hammer when you first fit it.
Good Luck!

These milled-down caps would be a good thing for the big three to keep on hand. It looks like many of us have gone through this process.

Just for grins, before I did the cutting, I asked what a set of new caps was worth. Fifty-something was the reply. How much to shorten them? Then how much would you be willing to pay? The actual shortening took not long at all, maybe ten minutes for both, dressed and ready to go back. Just do it!

Hello!
I took about 9mm off from the bearing dust caps with lathe.
It´s nice now. I had to be very careful not to press caps too deep. (I think I took little too much off......)

UPDATE:
I wanted to post a response and thank Bill for the suggestion to use the muffler clamp on the cap to use as something to pry against for removal. This worked like a charm. It was still a PITA to remove but in time it came off. Once off I put the cap in a vise and used the hacksaw on the thing and in a couple minutes i had a 7mm shorter dust cap. Once its cut short I filled the inside and outside edges of the cut and cleaned the shavings out of the cap. Reinstalling was a bit of a pain as it didnt want to seat the first 50 times, but eventually i got it. It went in too far on one wheel and the hub brake rotor when turned was obviously binding. I went back to the muffler clamp and as i tightened it on it acted as a press and pushed the cap out from the hub slightly to where there was no longer any binding.
I put the wheels back on and the center caps fit.
Thanks Rennlist

looks like you may have avoided this if you used a diff center cap
the cap you're using is probably 993.361.xxx.xx it concaves inward, 928.361.xxx.xx bubbles outward...
1st pic is 993, 2nd is the 928 GTS cap, may not look a lot diff but believe me they are
