I just had mine drilled to accept the newer Lug/stud set up. The machinist went to 23/32 which is .71875 out from .68 and some change. He claimed that would be tighter tolerance than the original set up. He said the mag lugs are generally a lot more loose than you'd imagine. After mounting and even just finger tight, I measured from the rotor snout to the bore I.D. and got less than half a millimeter run out all the way around. The second lug nut tightened up any movement and by the time I ran the third one in, there was no movement. Fourth one sealed the deal. Crossing my fingers...
I'm in the process of polishing them. 400-600-800-1000-1500-2000 and polish. I hate it. Not sure if I'm going black or gunmetal on mine. The car is Yukon (pale) yellow.

That's cool, how much did it cost you to have them machined? I just got a set of wide five 5-spokes, and some of the lug holes are already oversized. I was thinking about trying to sleeve them back to the original size, but maybe I should just have them all bored out. I was looking online a bit and saw that there's a variety of different ODs for the shanks of mag lugs. |
I got a quote from the machine shop we use at work for $475, but my guy charged me $150 under the table. As stated, he just drilled them out. No computer, no lock down (claimed the minimal runout would take care of itself) and no guarantee! We'll see if I die. I'm ready. |

Supreme center caps pop into these nicely. Actually, three of mine popped in nice and tight. One of them, I was able to pull back out by hand with some effort. I wrapped it in electrical tape. I went once around and that was too much. Paint thickness might be enough to tighten it up. Don't know yet. A little more polish and I'm ready to paint these and then I'll find out. The three other ones even required a couple of taps from behind with a hammer handle to get them back out. Part number is 98-1163 and 3.25 is the bore they are supposed to fit.
*edit*
Finished the front two. I'm going grey on one side and black satin on the other. Couldn't decide and figured I didn't have to. I took the tension ring out of these center caps and stretched it out a little. Then, I heated the tabs up with a heat gun and pushed them onto a little Kerr jar I found with a rounded bottom. That pushed them out just a little. Now the caps fit like they were made for these wheels.
