I just bought a set of these wheels from Luke @ Lindsay and they did indeed come with center caps (but he tells you that they don't, so this must be a recent change that TD has made). I haven't installed the wheels yet, but I assume the center caps will clear everything (based on an earlier post).
A couple other points of interest:
1) I measured the wheel width and they are actually 9.75" wide. I always thought a 9" wheel was exactly 9" wide, but apparently not.
2) The TD wheels feel heavier than my CCWs (even the wider rear 19'x10") - those CCWs are super light
3) I will be running 275/35zr18 r-comps (R888s) on all 4 corners. I'm lowered, but I have had all the fenders rolled, so I don't really expect to have rubbing issues, or if I do, they will be very minor and only under track conditions.
