Help - front bearing dust caps falling off

Help - front bearing dust caps falling off
I have an FC.
I have lost 2 front wheel bearing dust caps at the track. Is the hot air in the hub pushing out the caps? If this is the problem I will drill a small hole in the caps as a vent.
Or are the hubs heating up and letting the dust caps fall out?
Any tips or tricks to keep them in?

We are talking a 1/16" hole here. I'd rather have a very small hole in the cap than have them fall off completely since they aren't made anymore.
I don't know where to get new ones. I bought a set off a member to have as spares.
I have 4 spares now, after replacing the lost one I will have 3 spares. I did not want to drill them if that was not the problem.

The 4 lug guys parting out cars seem to be a good source for spare caps. I got one set with a set of 5 lug hubs I got as spares, then another set from a 4 lug guy stripping the car. And I have 1 NIB one from Mazdatrix.
I've lost 2 in a couple years of tracking the car. I've caught them a handful of times half way out. Drilling them seems to be the ticket.

Actually a .050" hole will work just fine. In addition, if you are worried about dust/dirt, find a small aircraft rivet that fits in the hole with clearance and use that.

I guess I was referring more to the possibility of trapping water inside if you were to wash it with a pressure washer. I guess I could find something to cover them for washing.
Does anyone have a good measurement for 5 lug front hubs so we could possibly find a different vehicle that would use the same sized dust cap? There has to be something out there that would fit. None of the junk yards in my area (southern Kansas) have any 2nd gen rx7s...

It takes a lot of heat to get them to pop out.

I have been racing my FC since 1997. I have gotten the front brakes hot enough to crack rotors and melt seals out of the calipers, but I have never had a cap pop off. Either I am really fortunate or I am not using as aggressive a pad as you guys. Also, do you think it could be grease related? I have always used premium greases that don't melt out. I wonder if the type of grease and the vapours it releases could be a cause.

Yes I'm sure fresh caps fit great. Slightly flaring the outer diameter of used caps may help keep them tight as well. Also I have heard using a punch on the ID to put a small dimple in the cap every 90 degrees will add a little more resistance.
I'm using redline grease, it is holding up fine.
