On Saturday I received a "little box of billet" and finally found some time to install them today.
I've also taken the liberty of preempting many of your posts with the following:
1. Yes, I know my wheels are dirty. I'm washing the car later today.
2. Yes, I have the Centric Posi Quiet low dust pads.
3. No, while I had the wheels off, I did not bother to clean the tubs or clean the calipers.
4. Yes, I am thinking about painting the SRT letters on the spoke black.
These caps are great quality and fit like stock. Here is the link for those interested:

some people have noticed that the caps are slightly loose or "jiggle" when you drive. it didn't bother me at all, but, seeing that it was a question coming up, i thought i would find a solution.
at first, FreebirdSRT suggested I silicone down the caps. after more discussion i thought of adding a washer and we agreed that i would try that before silicone.
i went to the hardware store and for $1 i bought a package of 24x #10 washers. now, each screw has:
lock washer (BT provided)
flat washer #1 (BT provided)
flat washer #2 (needs to be larger than #1)
center the cap on the wheel and secure with blue painters tape. hand tighten each screw, then go back and tighten each one with a 1/4 socket screwdriver. remove the blue tape and bingo....you've got a securely centered cap.
hope this helps.
