I'll try to snap a picture of my safety-wired dust cap this weekend - I'll be swapping tires at the track.

I've had no wheel clearance issues with three types of wheels - D90's, 968 5-spokes, and 951 Turbo Cup wheels.

Speaking of turbo cup wheels: I borrowed a set of the mag PDs one time that had a small machined collar or sleeve inside the hub center for the front wheels. It was held in with a set screw and it fit up tight against the hub dust cap to hold it on. Not factory, just something that a race team had put in there when using the wheels at some point. Thought that was a neat technique, but would be too much effort/cost to have a set made up for my wheels (new dust caps would be cheaper).

As requested, here are a couple of shot of my safety-wired dust caps. Sorry about the pic quality - I was in a rush to pack up and get home from the track. (Funny, no matter how hard I try, I seem to always be one of the last ones to leave the track!)

Anyway, here they are to give you an idea of how it looks:

Search is my friend! I lost two left caps this weekend - this looks like my solution!

Safety wire will work but try cleaning the cap and the hub of grease and applying some LOCTITE. Then, use a BFH (Big Friggin Hammer) to egg shape the cap.

RE hubs use a set screw, which I very much prefer over the tie-wire fix.

Ive also used a lot of alum. tape over the wheel center to keep from losing caps on wheels w/ large hub openings (e.g. BBS).

It's the grease expanding when it gets hot that pushes the caps off, solution: Drill a very small hole in the center of the cap.

The 25 YO castings are going limp. It's just a matter of time before the bearing seats give.
