I keep forgetting about the step in the hub center, that it is the larger Mustang size at the flange, and smaller away from it for the smaller MN12/FN10 hub. The rear is not that way, but I think I have an extra pair of hub centric rings for them.
I might practice on some old GT rotors that came with some dual piston calipers I bought. I told them not to send the rotors but they did, shipping wasn't real bad I just didn't want all that weight and poor shipping box.
The places that would do it (places that do rims) want way too much money to do them, 10x the price of the rotors, everyone else seems to think it is too hard, or not worth their time. I am not a machinist but know they wouldn't be blind drilling these holes, but once setup to do one hole that the other 19 are easy.
I gotta do something about the brakes, but I guess it would be nice if it was actually running at more than 50% once it heats up, it stops okay now, doesn't always go so well.
About the lugs, after seeing how badly beat up there were on the car, 2 were rounded completely, and one the lug erupted through the end. I mounted the tire to a Thunderbird and all 4 lug nuts tightened up completely, but the studs are longer on the MN12/FN10 than the looked like on the LS. Especially with a pretty thin wheel, not 1 inch thick hub like my aftermarket wheels. 611-117 seem like the shoulder that goes into the wheel is too long, the wheel isn't that thick, but the regular wheels seem to be.
