After Market Rim - Which Lug Nut? My problem right now is that my car (2001 Trans Am WS6) is at the mechanics now, I have new exhaust, tires, and rims. The exhaust was put on and the tires and wheels together and balanced, but when I bought the rims they didn't come with lug nuts!
So I've been hopping from store to store asking what the hell I need for this rim and no one knows! These are after market rims I bought, Z06 replicas.
What the mechanic told me so far is that:
The rims are:
Size: 18x9.5 inch
Bolt Pattern : 5x120.65mm (Same as 5x4.75)
Offset/ET: 57 MM
The lug nut isn't an "acorn" style, its a "shank" style. The lug nut is supposed to fit through the opening of the hole. The hole, or rim, is 9/16ths thick. The lug nut size is "M12 1.5". He said it should be like 1/2 inch long, or 3/4 inch long if it has a washer with it. Which is another problem because no one knows if there should be a washer with it. And if it needs a washer, what thickness and size it should be. I was told if there's no washer though that it would ruin the rim.
Any help would be appreciated. Here are the pics:

Just go and get some lugs for an f-150. Its a lock washer built onto the lug(I think). Thats the style that goes in that rim. I could be wrong, so please check.

You guys aren't gonna believe this lol...
So after much searching around, apparently what I need is a shank style, flat seated lug nut with a 12mm X 1.50 thread size. Since the hole depth is 9/16" I need a 12/16" (3/4") long shank and a 3/16" thick washer to go with it so it fits properly. This isn't a problem:

Now here's the kicker...
The standard shank diameter, no matter which company that I check, is 0.685".
This rims have a 0.625" diameter.
Result? I have to take the rims to a machine shop to get the holes bore'd out bigger so they can fit the standard size lug nut!
I bought them off ebay, and I called the guy who was chineese, and asked if I could have the manufacturer of the rim to ask them the exact make and size of lug nut hat will fit my car. He said "You don't need to know." then when I insisted, he said "They're in china, what are you going to call them? They won't understand you."
But yeah, that's gonna cost me $140 to get the holes bore'd out, and if they screw up just one rim, the rest are pretty useless!

$140 to bore out 20 holes? thats a little pricey. My dad has a machine shop and could get that done in an hour easy so it would be like $50. Be sure to look around a little so you don't get over charged.

Okay so i got the lugs on, after a while they became loose though, is this normal for new lugs to do that? Do they need to be "worn in"? They're Gorilla Lugs so they're good quality.
I should probably also mention that there's only 4 lugs in right now (the rest come tomorrow, would that do it?
